Combined Endoscopic Third Ventriculostomy and Lumboperitoneal Shunt Surgery in an Elderly Patient With Complex Hydrocephalus: Mixture of Late-onset Obstructive and Communicating Hydrocephaluses.

Abstract

Obstructive hydrocephalus due to aqueductal stenosis (AS) is a disease that mainly occurs in children. Late-onset obstructive hydrocephalus due to AS can rarely occur in elderly patients.1 The treatment of obstructive hydrocephalus due to AS by endoscopic third ventriculostomy (ETV) shows good results.2 However, ETV alone cannot be used for treating elderly patients with complex hydrocephalus. This complex hydrocephalus may be accompanied by obstructive and communicating hydrocephaluses due to different causes.3 We present the case of an elderly patient with rare complex hydrocephalus, a combination of lateonset obstructive and communicating hydrocephaluses, treated using combined ETV and lumboperitoneal shunt (LPS) surgeries.
