A Prospective Study and Analysis of Ventriculoperitoneal Shunt Surgery: Their Indication and Complication in a Single Tertiary Care Center

Abstract

Background Ventriculoperitoneal (VP) shunt insertion is routinely performed for the treatment of hydrocephalus due to different indications like congenital, infective, tumor, posttraumatic, and normal pressure hydrocephalus (NPH). A lot of common and rare complications following this procedure have been reported. Objectives To analyze the clinical profile, indications, anesthetic, and postoperative complications for VP shunt surgery in our center. Materials and Methods This prospective clinical review study was conducted in the Department of Neurosurgery, Institute of Medical Sciences, Banaras Hindu University, Varanasi, between October 2018 to January 2020 and included 454 cases of hydrocephalus who underwent VP shunt surgery. The data was compiled and analyzed. Results A total of 454 patients with male predominance were studied. Pediatric and adolescent patients were 48.9% (222/454). Obstructive hydrocephalus due to tumors was the etiology of 48.7% (221/454) cases. The incidence of overall shunt complications was 9.7% (44/454), of which obstruction and infection was 5.9% (27/454) and 3.1% (14/454), respectively. Factors associated with increased shunt complications include redo and infective etiology and cases having higher protein in perioperative cerebrospinal fluid (CSF) analysis. Neuronavigation, antibiotic-impregnated shunt and biventricular shunt are associated with lower complications. Conclusion Obstructive hydrocephalus due to tumors happened to be the most common cause of VP shunt, and shunt obstruction is most common complication, especially in infective and redo cases.
