Abstract Background  Ventriculoperitoneal shunt (VPS) is a common technique employed to treat the second most common congenital brain malformation, “hydrocephalus.” Postshunt insertion, the consequent complications and factors contributing to shunt malfunction are much fought occurrences. The current study was planned to assess the effectiveness of the procedure, analyze the complications of VP shunt, and recognize the factors influencing shunt malfunction. Materials and Methods  The present study was a retrospective observational study, which was conducted at the Department of Neurosurgery, PGIMER RML Hospital, New Delhi, from August 2016 to July 2018. Patients with hydrocephalus requiring shunt intervention were included in the study. A Chhabra “slit n spring” hydrocephalus shunt system was inserted in all patients. All patients with VP shunts were followed to assess for any postshunt complications. Results  Out of 541 patients for whom VP shunt was inserted over a period of 2 years, 126 (23.3%) patients developed complications. The most common cause of hydrocephalus for which VP shunt was done was tubercular meningitis (39.3%, n = 63), followed by ventriculitis (12.38%, n = 20), congenital hydrocephalus (8.87%, n = 14) and aqueductal stenosis (5.54%, n = 03). The most common complication in our study was obstruction of proximal end of the catheter by debris, which was noted in 50 patients (39.68%). The second most common complication was poor peritoneal absorption or obstruction of lower end (21.43%, n = 27 cases). Abscess along the shunt was seen in 21 patients (16.67%). Complications were mostly documented in cases with hydrocephalus due to tubercular meningitis (TBM) (39.3%, 63 patients) and ventriculitis (12.38%, 20 patients). Other complications were hyperemia with superficial ulceration or complete exposure of skin overlying the tube (11.9%, n = 15), overdrainage of the ventricles leading to chronic subdural hematoma ( n = 14, 11.11%), and infection around the distal catheter (4.76%, n = 6). Conclusion  VPS procedure led to a complication in several patients, with the most common being obstruction of proximal catheter and poor peritoneal absorption or obstruction of lower end followed by abscess and infection.
