Role of neuroendoscopy in the management of patients with tuberculous meningitis hydrocephalus.

The role of neuroendoscopy in patients of tuberculous meningitis with hydrocephalus (TBMH) is not yet established. We present details of endoscopic morphology, and analyze outcome of Neuroendoscopy performed in 28 patients (15 males and 13 females, average age 23 years) of TBMH in last 2.5 years. Endoscopic procedures performed included endoscopic third ventriculostomy (ETV) alone (n=19), ETV with monroplasty (n=2), and septostomy (n=2), ETV with decompression/biopsy of tuberculoma (n=2) and with abscess drainage (n=1). Outcome was assessed on the basis of clinico-radiological improvement, need for external shunt and complications. Outcome was satisfactory in 14 (50%), acceptable in five (18%) and unsatisfactory in nine (32%) patients. Overall, 19 (68%) patients benefited from endoscopic intervention. Cerebrospinal fluid (CSF) leak (n=2) and per-operative bleeding (n=1) were the only complications encountered. Endoscopy appears to be helpful in a considerable number of patients with TBMH, and should be considered as the first surgical option for CSF diversion surgery in these patients. External shunt should be reserved for those who fail the endoscopic CSF diversion.
