Abstract
BACKGROUND: Myelomeningocele is associated with hydrocephalus in 35% to 90% of cases. Hydrocephalus is usually treated with insertion of ventriculoperitoneal shunt; however, there is growing evidence that endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) is an alternative. OBJECTIVE: To compare the success rate and morbidity of ETV with CPC and ventriculoperitoneal shunt (VPS) as the primary treatment of hydrocephalus in patients with myelomeningocele. METHODS: A prospective study from January 2016 to February 2019, involving 46 patients with myelomeningocele who developed hydrocephalus after repair in a tertiary hospital in southwestern Nigeria. Biodata and preoperative features of hydrocephalus were documented. ETV + CPC or VPS was done using standard operative techniques. Patients were followed up monthly for 6 mo. RESULTS: There were 23 patients in the ETV + CPC arm and 22 patients in the VPS arm. Morbidities were cerebrospinal fluid leak, 8.3% in the ETV + CPC arm and 4.5% in the VPS arm, wound dehiscence, 13.6% in the VPS arm, none in the ETV + CPC arm. At 6-mo follow-up, success rate for ETV + CPC was 60.9% and 59.1% for VPS, P = .9. CONCLUSION: ETV + CPC had similar success rate with VPS at 6 mo with lower morbidity. ETV + CPC should be considered a viable alternative when treating patients with myelomeningocele and hydrocephalus.
