Endoscopic third ventriculostomy: Complications and avoidance

Introduction. Endoscopic third ventriculostomy (ETV) is the treatment of choice in obstructive hydrocephalus. It has become the main standard choice in management since 1962. However, there is scant data regarding the complications from clinical or multi-centre trials. This study highlights the specific complications and prevention methods related to ETV in Neurosurgical Teaching Hospital, Baghdad, Iraq. Methods. It is a prospective case series study conducted on cases in the Neurosurgical Teaching Hospital in Baghdad, Iraq, from January 2014- October 2019. We selected ninety patients. The sample selection was convenient as any patients admitted in the study period who met the selection criteria were included. All included patients underwent a Computerized Tomography scan or Magnetic Resonance Imaging in the periprocedural management. Results. Ninety cases have 59 (65.5%) females and 31 (34.5%) males. The most common cause of hydrocephalus is congenital causes (51 cases (56.6%), especially within the first decade of life. Aqueduct stenosis is the leading cause in 37 cases (72%). ETV complications were found in 32 cases (35.5%). The most common cause of complications is congenital cases of 14 (15%). Intraoperative complications include bleeding (mild, moderate, and severe) in 18 cases (20%). Mild bleeding constitutes 15 cases (16.6%) of all complicated cases. Conclusion. ETV is a standard procedure in the management of obstructive hydrocephalus. The complication rate is found in around one-third of the cases in our study. Surgeons’ selection of indicated patients and better surgical experience decrease the failure rate of ETV and complications
