Abstract:
Endoscopic third ventriculostomy (ETV) is increasingly used in place of shunt revision for shunt malfunction (secondary ETV). This review provides a comprehensive overview of preoperative, operative and postoperative considerations for patients undergoing a secondary ETV. Preoperatively, patient selection is vital and there is evidence that secondary ETV is more effective than primary ETV in certain hydrocephalic aetiologies. Operative considerations include use of neuronavigation and consideration of surgeon technical experience due to anatomical differences that are likely to accompany chronic shunting, management of existing shunt hardware and the use of temporary external ventricular drains or short/long-term ventricular access devices. Postoperatively, there are varying institutional practices with regards to ICP monitoring and length of follow-up after discharge. Finally, this review examines the slit ventricle syndrome as a special case requiring a different approach.
