The neurosurgical team of Mekelle University’s Ayder Hospital struggles to save the life of a poor farmer from a deadly brain tumor. A critically ill patient who faced death unless he underwent emergent brain surgery. An intense multi-hour confrontation with a brain tumor. This became an almost everyday occurrence for our team.
I had come to Ayder Comprehensive Specialized Hospital in Mekelle, Ethiopia in 2015 to start a neurosurgery program. This was a federal teaching teaching hospital and part of a university medical center serving about 15 million people. We wanted to create a sustainable medical service that also train neurosurgeons.
As the family said goodbye to him he left the ICU for the operating room. He had been intubated and resuscitated in the emergency room where he presented with coma. A young uneducated farmer from a remote primitive area who had been deteriorating for a year and half. Tumors in this part of the world are large and angry because they present so late.
The MRI of the brain showed a 10 centimeter ependymoma in the fourth ventricle which was highly vascularized. This is the type of case neurosurgeons dream of, a mix of danger and hope.
The residents and fellows do the initial opening until the back of the brain is exposed which takes the first hour of surgery. I can see the tumor erupting to surface with very swollen blood vessels around it. Instead of the ependymoma (an easier tumor to remove) this was going to be hard. I begin working a millimeter at a time. Gently dissecting tumor from brain, isolating and separating scar bands and blood vessels. Using directed light and magnification for the next 8 hours I cannot take even a 5 minute break. Removing the tumor means there is constant blood loss. The brain receives more blood than any other organ. Tumors cause extra blood vessels to grow into them. As you control one bleeder another 2 start.
By the fourth hour into surgery he has lost 5 liters of blood and his blood pressure is fragile. By the sixth hours there is still about 20% of the tumor left which is covering the cerebral aqueduct. This must be removed to allow flow of cerebrospinal fluid. We are millimeters away from vital areas that cannot be damaged.
Another 2 hours goes by and there are times when the blood loss starts again and pressure gets low even with another 2 units. After 8 hours from the beginning of my part of the surgery the tumor is completely removed. The patients blood pressure is holding thanks to high dose epinephrine (a drug to raise blood pressure in critical patient). Now comes the hardest time. Will the patient wake up? He goes to the intensive care unit and we wait. After a few hours he begins to move in a way that suggest he will emerge from coma.
This is the life of neurosurgeon. Fighting to stay on the brink of life for hours at a time.
At Mekelle University Department of Neurosurgery-Ayder Comprehensive Specialized Hospital we have been developing an expertise in the treatment of stroke due to rupture of a cerebral blood vessel culminating in a successful clipping of a ruptured aneurysm.
Subarachnoid hemorrhage in Africa and Ethiopia
Stroke in Africa and more specifically in Ethiopia remains an almost taboo subject. It is shrouded in superstitious beliefs of curses and hidden poisons among most of the population who receive little public health education in what schooling they attend. A significant form of stroke is that due to rupture of a cerebral artery which creates the phenomena of subarachnoid hemorrhage. It is estimated that worldwide 9 in 100,000 years of human life or 1 in 50 people will suffer a subarachnoid hemorrhage.
Although rupture of a brain artery causing subarachnoid hemorrhage may lead to sudden death there are many patients who if given advanced treatment can be saved and return to functional lives. To receive this treatment requires special trained medical centers with experts in emergency medicine, neurology, radiology, anesthesiology, and neurosurgery. Up to now these centers have been lacking in most of Africa.
How subarachnoid hemorrhage causes damage
When a brain artery ruptures it may cause severe pressure on the brain which can kill or permanently disable. This type of large clot is unusual in most patients. Instead what happens is that the blood causes surrounding blood vessels to defensively constrict limiting the blood supply to the brain. This pathological process is vasospasm. Additionally the blood leakage can lead to chemical abnormalities of sodium or the mal-absorption of a fluid called cerebrospinal fluid which normal is produced and absorbed in a balanced way. Once a blood vessel ruptures once it will likely rupture again as each day goes by, a ticking time bomb.
Treatment of subarachnoid hemorrhage and ruptured cerebral aneurysms
Successful treatment of ruptured cerebral artery aneurysms requires rapidly making the diagnosis and beginning aggressive resuscitation of vasospasm and electrolyte abnormalities. The blood pressure must be closely controlled and the patients respiratory system supported. Upon stabilization the patient should undergo timely surgery or intravascular treatment to reduce the incidence of a second deadly rebleed. Whether microsurgery or intravascular treatment is better remains controversial.
A representative case at Ayder Comprehensive Specialized Hospital
The following case is an example. A 55 year old Ethiopian grandmother suddenly complains of the worst headache of her life and goes into a coma. She is brought to Ayder Comprehensive Specialized Hospital in Mekelle, Ethiopia on the Mekelle University medical campus. Emergency physicians and internal medicine specialists stabilize her condition and perform a CT Scan which shows subarachnoid hemorrhage and suspician of a ruptured anterior communicating artery aneurysm.
The patient is comatose with electrolyte abnormalities and out of control high blood pressure. She is admitted to the medical intensive care unit where she receives supplemental oxygen, high doses of fluids to correct hyponatremia and try to overcome the vasospasm, as well as a special medication, nimodipine, which can help to counteract vasospasm.
After 2 weeks she regains consciousness and a repeat CT angiogram ( a special CT scan which shows the arteries of the brain in detail ) is done which now clearly shows a 5mm aneurysm. Now that she is stable surgery must be done soon before a fatal rebleed can occur.
She is taken to the operating room with a specially trained anesthesia team which finely controls her blood pressure during surgery. An opening is made in the front and side of the skull while under general anesthesia and carefully working under the brain the ruptured blood vessel is exposed and clipped to prevent rebleeding.
The Department of Neurosurgery at Ayder Comprehensive Specialized Hospital of Mekelle University treats over 1000 significant head injuries every year including performing an average of 2.5 operations per day. All patients should undergo standard multiple trauma resuscitation and assessment by Advanced Trauma Life Support Guideline.
Since 2015 the Department of Neurosurgery at Mekelle University has instituted a standard head injury protocol (now revised in 2019) for the assessment and treatment of children and adults at Ayder Comprehensive Specialized Hospital based in part upon the local settings of Northern Ethiopia and the international guidelines including that of the Brain Trauma Foundation
Intracranial pressure monitoring is not economically feasible in Ethiopia but we are developing research protocols to look at optic nerve sheath diameter by serial ultrasound in the near future.
Adults Initial Assessment The management of patients with a head injury should be guided by clinical assessments and protocols based on the Glasgow Coma Scale and Glasgow Coma Scale Score.
Indications for referral to hospital Adult patients with any of the following signs and symptoms should be referred to an appropriate hospital for further assessment of potential brain injury:
1. GCS<15 at initial assessment (if this is thought to be alcohol related observe for two hours and refer if GCS score remains<15 after this time)
post-traumatic seizure (generalized or focal) focal neurological signs
2. signs of a skull fracture (including cerebrospinal fluid from nose or ears,
hemotympanum, boggy hematoma, post auricular or periorbital bruising)
3. loss of consciousness
4. severe and persistent headache
5. post-traumatic amnesia >5 minutesrepeated vomiting (two or more occasions)
6. retrograde amnesia >30 minutes
7. high risk mechanism of injury (road traffic accident, significant fall)
coagulopathy, whether drug-induced or otherwise.
Indications for head CT scan Immediate CT scanning should be done in an adult patient who has any of the following features:
1. eye opening only to pain or not conversing (GCS 12/15 or less)
2. confusion or drowsiness (GCS 13/15 or 14/15) followed by failure to improve within at most one hour of clinical observation or within two hours of injury (whether or not intoxication from drugs or alcohol is a possible contributory factor)
3. base of skull or depressed skull fracture and/or suspected penetrating injuries
4. a deteriorating level of consciousness or new focal neurological signs
full consciousness (GCS 15/15) with no fracture but other features, eg
— severe and persistent headache
— two distinct episodes of vomiting
5. a history of coagulopathy (eg warfarin use) and loss of consciousness, amnesia or any neurological feature.
CT scanning should be performed within eight hours in an adult patient who is otherwise well but has any of the following features:
1. age>65 (with loss of consciousness or amnesia)
2. clinical evidence of a skull fracture (eg boggy scalp haematoma) but no clinical features indicative of an immediate CT scan
3. any seizure activity
4. significant retrograde amnesia (>30 minutes)
5. dangerous mechanism of injury (pedestrian struck by motor vehicle, occupant ejected from motor vehicle, significant fall from height) or significant assault (eg blunt trauma with a weapon).
In adult patients who are GCS<15 with indications for a CT head scan, scanning should include the cervical spine.
Indications for admission to hospital An adult patient should be admitted/observed to hospital if:
1. the level of consciousness is impaired (GCS<15/15)
2. the patient is fully conscious (GCS 15/15) but has any indication for a CT scan (if the scan is normal and there are no other reasons for admission, then the patient may be considered for discharge)
3. the patient has significant medical problems, eg anticoagulant use
4. the patient has social problems or cannot be supervised by a responsible adult.
Referral to neurosurgical unit A patient with a head injury should be discussed with a neurosurgeon:
1. when a CT scan in a general hospital shows a recent intracranial lesion
when a patient fulfills the criteria for CT scanning but facilities are unavailable
2. when the patient has clinical features that suggest that specialist neuroscience assessment, monitoring, or management are appropriate, irrespective of the result of any CT scan.
3. All salvageable patients with severe head injury (GCS score 8/15 or less) should be
4. transferred to, and treated in, a setting with 24-hour neurological ICU facility.
Children Initial assessment
Great care should be taken when interpreting the Glasgow Coma Scale in the
under fives and this should be done by those with experience in the management of the young child. Pediatric Glasgow Coma Scale and Scoring (for use in patients under five years of age)
Indications for referral to hospital In addition to the indications for referral of adults to hospital, children who have sustained a head injury should be referred to hospital if any of the following risk factors apply:
1. clinical suspicion of non-accidental injury
2. significant medical co-morbidity (eg learning difficulties, autism, metabolic disorders)
3. difficulty making a full assessment
4. not accompanied by a responsible adult
5. social circumstances considered unsuitable.
Indications for head CT scan Immediate CT scanning should be done in a child (<16 years) who has any of the following features:
1. GCS≤13 on assessment in emergency department
2. witnessed loss of consciousness >5 minutes
3. suspicion of open or depressed skull injury or tense fontanel
4. focal neurological deficit
5. any sign of basal skull fracture.
CT scanning should be considered within eight hours if any of the following features are present (excluding indications for an immediate scan):
1. presence of any bruise/swelling/laceration >5 cm on the head
2. post-traumatic seizure, but no history of epilepsy nor history suggestive –of reflex anoxic seizure
–amnesia (anterograde or retrograde) lasting >5 minutes
–clinical suspicion of non-accidental head injury
–a significant fall
–age under one year: GCS<15 in emergency department assessed by
–personnel experienced in paediatric GCS monitoring
–three or more discrete episodes of vomiting
–abnormal drowsiness (slowness to respond).
If a child meets head injury criteria for admission and was involved in a high speed road traffic accident, scanning should be done immediately
Indications for admission to hospital Children who have sustained a head injury should be admitted to hospital if any of the following risk factors apply:
1. any indication for a CT scan
2. suspicion of non-accidental injury
3. significant medical co-morbidity
4. difficulty making a full assessment
5. child not accompanied by a responsible adult
6. social circumstances considered unsuitable.
Referral to neurosurgical unit A patient with a head injury should be discussed with a neurosurgeon:
1. when a CT scan in a general hospital shows a recent intracranial lesion
2. when a patient fulfills the criteria for CT scanning but facilities are
3. when the patient has clinical features that suggest that specialist
neuroscience assessment, monitoring, or management are appropriate,
irrespective of the result of any CT scan.
4. All salvageable patients with severe head injury (GCS score 8/15 or less) should be transferred to, and treated in, a setting with 24-hour neurological ICU facility.
In hospital care All medical and nursing staff involved in the care of patients with a head injury should be trained and competent in the use and recording of the Glasgow Coma Scale. The GCS should not be used in isolation and other parameters should be considered along with it, such as:
–pupil size and reactivity
–respiratory rate and oxygen saturation
–unusual behavior or temperament or speech impairment.
Family members and friends should be used as a source of information.
Observations should be recorded on a chart
Children <3 years old who have sustained a head injury are particularly difficult to evaluate and clinicians should have a low threshold of suspicion for early consultation with a specialist pediatric unit.
Children who are admitted should be under the care of a multidisciplinary team that includes a pediatric trained doctor experienced in the care of children with a head injury.
Children should be observed on a children’s ward.
The risk of rapid deterioration is greatest in the first six hours after injury and then decreases. If the patient is admitted on the first day of the injury then repeat evaluation every few hours is indicated if high risk factors such as high energy injury, Glasgow coma scale < 15, or focal neurological deficit is present.
Medical staff should assess the patient on admission to the ward and should re-assess the patient at least once within the next 24 hours. Assessment should include: examination for the GCS, neck movement, limb power, pupil reactions, all cranial nerves and signs of basal skull fracture.
Any of the following examples of neurological deterioration should prompt urgent re-appraisal by a doctor:
–the development of agitation or abnormal behavior
–a sustained decrease in conscious level of at least one point in the motor or verbal response or two points in the eye opening response of the GCS score
–the development of severe or increasing headache or persisting vomiting
new or evolving neurological symptoms or signs, such as pupil inequality or
asymmetry of limb or facial movement.
If re-assessment confirms a neurological deterioration, many factors need to be evaluated but the first step is to ensure the airway is clear, and that oxygenation and circulation are adequate.
Clinical signs of shock in a patient with a head injury should be assumed, until proven otherwise, to be due to hypovolemia caused by associated injuries.
Whilst an intoxicating agent may confuse the clinical picture, the assumption that deterioration or failure to improve is due to drugs or alcohol must be resisted.
If systemic causes of deterioration such as hypoxia, fluid and electrolyte imbalance, or hypoglycemia can be excluded, then resuscitation should continue according to accepted trauma protocols.
After traumatic brain injury, agitation may be a sign of neurological deterioration, hypoxia, electrolyte disturbance, drug/alcohol withdrawal, or seizures. Medical evaluation should be done in conjunction with pharmacological therapy for behavior.
Therapeutic Goals and Interventions
Systolic BP < 90 mm Hg and O2 Saturation < 90% should be avoided.
Mannitol in doses of 0.25gram/kg to 1.0gram/kg may reduce ICP. Our usual regimen is to give an initial dose of 1.0 gram/kg and the start 0.25mg/kg every 8 hours. The dose can be increased up to 1.0 gram/kg and frequency up to every 6 hours as needed. It is most useful as a temporizing measure such as to treat a patient suspected of having a mass lesion which may be surgical while preparing that patient for surgery. It is most effective in bolus doses rather constant infusion which may be repeated every 6 hours. Most of the world wide experience deals with controlling intracranial pressure which is being monitored. It should not be a part of routine head injury management. Side effects of hypotension, increases in size of intraparenchymal brain hemorrhage, and kidney dysfunction may occur.
The use of mannitol for head injury treatment in developing countries without ICP monitoring has not been well studied.
1. Salvageable Head Injury with GCS 8 or less.
2. Deterioration from GCS > 8 to less for three days as above
3. Pre-operative .25gram/kg to 1.0gram/kg dose for suspected or known mass lesion. May be repeated intra-operatively.
4. Post-operative management of cerebral edema
Enteral feeding should be begun by 72 hours after injury. Hyperglycemia should be avoided as increased intracellular lactic acidosis can worsen brain injury.
Seizures and Seizure Prophylaxis
Prophylactic anticonvulsants does not reduce late seizure development or improve outcomes. However we face an unusual situation in Ethiopia where there are no intravenous anticonvulsants. We have had experiences of a few patients in the past few years whose developed early onset post traumatic seizures which where difficult to control while we were waiting for oral phenytoin to be absorbed which typically takes about 24 hours. Therefore we are changing our previous recommendation to start phenytoin or carbamezipine in any patient with an abnormal brain finding on CT Scan of the brain and continue for 7 days.
Anticonvulsant treatment indications:
Phenytoin use according to body mass and age for a seizure in the first few days and continued for one week.
Craniotomy for intraparenchymal lesion (evacuation of hemorrhagic contusion or lobectomy) or if a dural tear is discovered such as for depressed fracture
Routine single dose of Ceftriaxzone 1 gm IV on call for adults and 50mg/Kg in children for closed head injuries requiring surgery.
Single dose of periprocedural antibiotics for intubation only unless the patient has signs of aspiration pneumonia already present.
Low molecular weight heparin is contraindicated in the presence of acute head injury. If there is no large hematoma (intraparenchymal) then generally should wait at least five days before beginning low dose heparin 5,000 units BID or low molecular weight heparin Graduated stockings or pneumatic compression stockings if available are appropriate.
Profound hypercarbia may increase ICP and profound hypocarbia may decrease cerebral perfusion. Hyperventilation is to be avoided in the first 24 hours after injury. Temporary mild hyperventilation pre-operatively or intra-operatively may be used.
There is no sound scientific evidence supporting the use of steroids for head injury.
Under special circumstances such as post-operative swelling or diffuse cerebral swelling in a viable patients in consultation with neurosurgical staff pentobarbital at 3mg/kg/ hour may be given for up to three days to attempt to control brain swelling. Patients who have bilateral dilated pupils and decreased brain stem function are not candidates for this treatment modality.
Most of the studies suggest post-traumatic meningitis can be treated similar to community acquired bacterial meningitis with Ceftriaxzone 1 gm Q12h in adults. If no response is seen consideration can be given to adding Vancomycin and Meripenum for resistant organism. In our experience most patients respond to a 10 day course of Ceftriaxzone. Consideration can be given to performing a lumbar puncture for culture and sensitivity if CT Scan shows no mass effect. If staph aureus is identified then treatment should be extended for 21 days duration.
Surgical Management Guidelines
Note: The clinical progression of the patient must always be considered strongly in decision to do surgery or treat conservatively. Lesions affecting the temporal lobe area are at high risk of rapid deterioration especially within the first three days after injury.
–An epidural hematoma greater than 30 cm squared should be evacuated regardless of GCS score
–An epidural hematoma less than 30 cm squared, midline shift less than 5mm, and thickness less than 15 mm in a patient without neurological deficit can usually be considered for nonsurgical treatment if clearly clinically stable
–Acute epidural hematoma is best treated by craniotomy rather then burr holes. Tacking up of the dura to prevent rebleeding should be done.
Acute Subdural Hematoma
–An acute subdural hematoma with a thickness greater than 10 mm or midline shift greater than 5 mm should be evacuated regardless of GCS score
–Patients who have a large parenchymal contusion and acute subdural less than 10mm with an admission GCS< 9 and then subsequent deterioration may be a candidate for surgery.
–In severe cases of brain swelling. Bone flap removal and duraplasty may be necessary.
Surgery for Traumatic Intraparenchymal Lesions
–Surgery for resection of intraparenchymal lesions is not within the normal procedure guidelines for general surgery.
–Patients with focal intraparenchymal lesions who present with a GCS of 8 will be initially placed on medical management protocols.
–Patients with a GCS of 8 who deteriorate despite medical management will be discussed with the neurosurgical staff as regards to management
Chronic Subdural Hematoma
–A totally asymptomatic patient with evidence of a chronic subdural hematoma may be conservatively followed
–A symptomatic patient with chronic subdural hematoma should undergo timely operation
–The best outcome in chronic subdural hematoma was found in a prospective study utilizing the two burr hole technique with subdural drain placement. At Ayder an initial burr hole will placed frontally or parietally depending upon where the greatest thickness of the hematoma is found. If after irrigation of the subdural space the brain does not expand to the dura then a second burr hole will be placed. If the clot is gelatinous then the burr holes will be converted to a craniotomy. A pediatric feeding tube will always be place in the subdural space at least one centimeter beyond the proximal last side hole and exited through a separate stab wound.
–The subdural drain may be removed when the old blood drainage converts to CSF. The drain should be removed by the morning of the third day after surgery.
–After surgery while the subdural drain is in place the patient’s head should be kept flat to maximize brain re-expansion which will push out the remaining subdural hematoma
–If patient deteriorates following surgery after initial improvement or fails to improve then consideration for a repeat CT scan should be done.
Closed Depressed Skull Fracture
–Patients with a closed depressed fracture with a depression less than 1 cm and no neurological findings or associated hematoma requiring surgery are potential candidates for conservative treatment
–A closed depressed fracture with a depression 1 cm or greater (which is deeper then the inner table) and/or neurological deficit should under go timely surgical intervention.
–Patients with simple depressed fractures without dural tear or cerebral contusion require only routine pre-operative antibiotic prophylaxis and no anticonvulsant prophylaxis.
Open Depressed Skull Fracture
–Patients with an open depressed fracture greater than the depth of the calvarium should undergo surgery.
–Operation should be done within the first 48 hours after injury to reduce the risk of infection.
–The bone flap or fragments should be cleaned with betadiene and saline thoroughly before replacement
–A water tight closure of the dura should be attempted..
–Debridement of nonviable and contaminated brain should be done.
–A 24 hour course of intravenous Ceftriaxzone and Metronidazole should be given for cases where there is only minimal contamination and the dura is intact. Patients will then receive a 7 day oral course of Amoxicillin and Clavulanate (Augmentin) 500 mg every 8 hours for adults.
–An 7 day course of intravenous Ceftriaxzone and Metronidazole should be given for cases where there is extradual purulence, gross contamination or penetration of the brain especially if surgery was delayed more than 48 hours after injury.followed by a one week course of Augmentin orally.
–Post traumatic cerebritis or abscess requires 6 week course of intravenous antibiotics.
–Anticonvulsant prophlaxis should be given to all patients with dural laceration and open brain injury.
Traditionally surgery for hydrocephalus has been performed by neurosurgeons who undergo vigorous neuroscience basic training and supervised surgical experience of at least 5 years in length (longer in developed countries) after medical school. Recently there has been some discussion as to whether in African and other undeveloped countries general surgeons should be taught to perform ventriculoperitoneal shunts to treat hydrocephalus. The treatment of hydrocephalus should remain under the direction and in the hands of neurosurgeons.
Hydrocephalus as a medical condition has been recognized since the time of the ancient Greeks. The concept of surgery to treat hydrocephalus by diverting the flow of cerebrospinal fluid began in 1949, when Nulsen and Spitz implanted a shunt successfully into the caval vein with a ball valve. Between 1955 and 1960, four independent groups invented distal slit, proximal slit, and diaphragm valves almost simultaneously.
An estimated 750,000 people have hydrocephalus, and 160,000 ventricular peritoneal shunts are implanted each year worldwide almost always by neurosurgeons. About 56,600 children and adolescents younger than age 18 years have a shunt in place.
The incidence of hydrocephalus in Africa is estimated to be 145 per 100,000 which is three times higher than in the developed world. Thousands of these children will need surgical intervention, either ventricular peritoneal shunt or the newer, but still not clearly accepted as superior, endoscopic procedures.
A survey conducted among African neurosurgeons in 1998 showed that there were 500 neurosurgeons in Africa; that is, one neurosurgeon for 1,350,000 inhabitants, and 70,000 km2. That number is significantly increased now but the exact current number is unknown. Worldwide the average is 1 neurosurgeon per 230,000 but in Africa it can be as low 1 per 9 million people. It is believed there are 700 neurosurgeons currently or about 1 per 1,238,000 people which is an improvement but still not nearly enough. Ethiopia currently has about 30 practicing neurosurgeons and will soon be graduating about 30 newly trained neurosurgeons per year. This means Ethiopia will need about 450 functioning neurosurgeons taking into account expected population growth.
Although the training of neurosurgeons in performing ventriculoperitoneal shunts has become somewhat standardized via the World Federation of Neurosurgical Societies as well as international neurosurgical groups, the training of general surgeons to do this procedure has not been rigorously studied. There are very few publications about the results of general surgeons performing ventriculoperitoneal shunts but an a study from Kenya done in 2010 showed a significantly high complication rate of 65% with an infection rate of 9.1% and shunt malfunction rate of 11.1%. This was much different than reported by Dr. Warf , an American trained neurosurgeon who created a specialized center in Uganda, with a malfunction rate of 4%.
More recently endoscopic procedure to open the third ventricle to the cistern and coagulate the choroid plexus are gaining ground but not totally proven yet. These procedures clearly require specialized training and knowledge of anatomy of the caliber of a neurosurgeon and not a general surgeon.
The real issue was not really the shortage of surgeons but the bottleneck was lack of hospitals, operating rooms, and clinics. Additionally transportation to get healthcare is a real issue. Now Ethiopia has seen the light and has three training programs for neurosurgery in Ethiopia and are graduating about 30 per year. Again the problem is we have more surgeons than facilities to operate in.
African governments will see the idea of adding shunt placement to general surgery as an easy fix. In reality they are already overworked. I have taught medical students and general surgery residents. Many people think ventriculoperitoneal shunts are the easiest procedure but I always tell my neurosurgery residents and fellows it is not. Decisions about when to shunt, is the shunt working, is it infected? require experience and training. Academic following of outcomes, techniques, epidemiology requires an academic neurosurgery program take the lead.
Unfortunately there is no shortcut to capacity building. We are now training neurosurgeons for other African countries as well as Ethiopia. Eventually we will need more than 450 which will take time.
Finally I would say that our approach to hydrocephalus is changing rapidly. For us and the Uganda group we are consistently reducing the number of shunts we are doing each year. Whereas in the past we did nearly two hundred it is now going to be less than 100 even though we cover 20 million plus population with the highest myelomeningocoel rate in the world. We now recognize that many neural tube defect newborns have low grade infections which require antibiotics sometimes over 21 days until the csf is clear. Many times their hydrocephalus stabilizes after a few fontanelle taps. Although the post infectious group is rising ( we are in the infamous meningitis belt of Africa) similar we have avoided shunting by similar close follow-up. Our shunt infection rate is currently 3% because we identify these chronic low grade infections. I shutter to think what would happen if general surgeons with little experience are let loose upon this situation.
