Abstract
INTRODUCTION
We report our preliminary experience with two cases of tuberculous meningitis (TBM) in which endoscopic third ventriculostomy (ETV) was performed to treat non-communicating hydrocephalus. For many years, the insertion of ventriculoperitoneal shunts has been the standard treatment for hydrocephalus in patients with TBM, although the indications for and timing of surgery are not uniformly accepted. Shunt insertion is associated with a high incidence of complications, particularly with long-term follow-up. An alternative treatment for hydrocephalus in this group of patients would clearly be of great benefit. The indications for ETV have increased in the last decade, and there are reports of some effectiveness of the procedure in patients with hydrocephalus due to bacterial meningitis. To our knowledge, ETV has not been described in the management of TBM.
METHODS
We report the early results of our preliminary experience with ETV in two patients who presented with neurological compromise due to hydrocephalus and raised intracranial pressure. The clinical context and pre-operative investigation of these patients are presented. The emphasis is placed on the distinction between communicating and non-communicating pathologies as a guide to management options. We detail our surgical findings and the peculiar endoscopic challenges that the condition presented to us. Follow-up in these patients included clinical and investigational data suggesting early effectiveness of the procedure in converting non-communicating hydrocephalus into a communicating one, which can then be treated medically.
DISCUSSION
Endoscopic third ventriculostomy is presented as a new application of a procedure accepted for other indications in the treatment of non-communicating hydrocephalus. There are particular aspects of the use of this procedure related to the unique pathology of TBM that are significantly different. We explain our rationale for endoscopy in these patients, and suggest a protocol in which endoscopy may play a role in the management of patients with raised intracranial pressure due to tuberculous hydrocephalus.
