Endoscopic third ventriculostomy for management of hydrocephalus associated with Chiari malformation type II in children.

BACKGROUND: Hydrocephalus is commonly associated with Chiari malformation (CM) particularly CM type II. The traditional treatment of hydrocephalus in these patients has been cerebrospinal fluid diversion by shunts. Endoscopic third ventriculostomy (ETV) has emerged as an alternative procedure in these patients. PURPOSE: Assessment of the clinical and radiological outcomes of ETV in the management of hydrocephalus in children with CM II. METHODS: This is a prospective study conducted on 18 patients with CM II associated with hydrocephalus admitted to Cairo University hospitals between January 2020 and June 2021. These patients had been managed surgically by ETV. Clinical outcome was assessed based on improvement of manifestations of increased intracranial pressure while radiological outcome was based on the findings of postoperative computed tomography. In cases with early failure, serial lumbar puncture (LP) was performed for 2 days. RESULTS: ETV was performed as a secondary procedure in 4 cases. The overall success rate of the procedure was 72%, and its success rate as a secondary procedure was 100%. Serial LP was effective in decreasing early failure in 44.4% of cases. Radiological regression of hydrocephalic changes was detected in 50% of the cases. CONCLUSION: ETV is an efficient and safe procedure in the treatment of hydrocephalus in children with Chiari malformation II, particularly when performed as a secondary procedure. Serial LP following the procedure increases the success rate in patients with early failure.

Short-term outcomes of endoscopic evacuation of supratentorial spontaneous intracerebral hematoma: Early experience from developing country.

BACKGROUND: Minimally invasive endoscopic hematoma evacuation is a promising treatment option for intracerebral hemorrhage (ICH). However, the technique still needs improvement. METHODS: We report our early clinical experience of using this technique to evacuate supratentorial spontaneous intracerebral hematomas and evaluate its short-term outcomes. RESULTS: The study included 15 patients, basal ganglia hematoma was the most common location 62.5%, mean preoperative hematoma volume was 61.07 cc, mean ICH score was 3, and mean rate of hematoma evacuation was 89.27%. Factors that could be related to mortality were Glasgow Coma Score (GCS) on admission (P = 0.001), ICH score (P = 0.004); postoperative GCS (P < 0.001), postoperative hematoma volume (P = 0.006); intraventricular extension (P = 0.001), and rate of evacuation (P = 0.001). CONCLUSION: Endoscopic technique is a safe surgical option for evacuation of spontaneous supratentorial ICH. This minimally invasive technique could be helpful to provide better short-term outcomes for selected patients. However, in our experience, this minimally invasive technique did not change the outcome for cases presented with poor GCS on admission 4/15. Our results warrant a future prospective, randomized, controlled efficacy trial.
