Re-Ventriculostomy for Treatment of Obstructive Hydrocephalus in Cases of Stoma Dysfunction

Abstract

In this article, 12 re-ventriculostomies in the treatment for obstructive hydrocephalus are described. The etiology of the hydrocephalus was a benign aqueductal stenosis in 9 patients, a tumor around the aqueduct in 2 patients and intraventricular bleeding in one patient. In all cases the initial ventriculostomy was successful, but after a time interval of 2 weeks to 6 years the patients developed similar clinical symptoms as preoperatively. In all except one case the radiological findings spoke in favour of stoma closure. Intraoperatively the stoma was completely closed in 9 patients and in 3 patients a subtotal closure was observed. In all cases a re-ventriculostomy was performed bluntly with a Fogarty catheter in loco typico at the floor of the third ventricle. Of the 12 patients 6 had an excellent outcome postoperatively, one patient improved and one had a benefit from the re-ventriculostomy although he died of cardiac problems. In the remaining 4 patients the re-ventriculostomy was not successful and the patients needed a shunt operation. In conclusion, after initially successful endoscopic third ventriculostomy, re-ventriculostomy should be considered as a sufficient treatment option in case of suspected stoma dysfunction.
