Abdominal complications of ventriculoperitoneal shunts. Case reports and review of the literature

Abstract

Ventriculoperitoneal (VP) shunting of cerebrospinal fluid (CSF) is the standard therapy for the management of hydrocephalus. Before the advent of silastic, early abdominal complications were frequent and finally led to the abandonment of this technique for management of hydrocephalus. With the use of silastic shunt tubing, VP shunts have once again gained favor as the procedure of choice. Although there are now considerably fewer complications from VP shunts, the presence of an intraperitoneal catheter can still initiate various complications. Abdominal complications of VP shunts are reported to be from 10-30 per cent, thus remaining clinically important for early recognition and treatment in patient management. An awareness of these complications is necessary in creating an index of suspicion for the primary physician whose patients harbor a VP shunt and present with abdominal symptoms. This report presents five cases of children with abdominal complications of VP shunts (four pseudocysts and one umbilical granuloma with spontaneous drainage of CSF). Additional abdominal complications of VP shunts are discussed, as well as diagnostic and therapeutic alternatives in order to improve and expedite accuracy in diagnosis and provide simplicity and efficiency in treatment.
