title: [Rare intra-abdominal complications of a ventriculoperitoneal shunt: report of three cases].
abstract: Three cases of rare intra-abdominal complications of ventriculoperitoneal shunt (VPS) surgery are reported. Case 1 was a 32-year-old male who had undergone VPS surgery for hydrocephalus following meningitis on July 10, 1980. Two weeks later he developed fever and a cystic mass about 10 cm in diameter in the right hypochondrium. Shuntography and a barium enema study demonstrated a pseudocyst at the distal end of the shunt. The cyst wall was excised, the peritoneal tube removed, and VPS converted to a ventriculoatrial route following which the pseudocyst resolved. Case 2 was a 49-year-old female who developed hydrocephalus following subarachnoid hemorrhage, and VPS surgery was performed on March 10, 1989. Two weeks later, she developed fever and right upper abdominal pain. Abdominal x-ray and CT scan revealed a right subdiaphragmatic abscess. The abscess was drained and the shunt system was removed on April 4. VPS was placed again on April 21 without further complications. She was symptom free for the next 7 years. Case 3 was a 57-year-old female who presented in a semicomatose state after falling from bed on May 5, 1995. CT scan showed left-sided acute subdural hematoma (ASDH) for which surgery was performed. Her neurological status improved postoperatively. She eventually developed hydrocephalus and left-sided subdural effusion for which right VPS and left subduroperitoneal shunt (SPS) surgery was performed on January 25, 1996. The peritoneal end of the tube of the SPS protruded out of the anus one and a half year after shunt placement. The entire SPS system was removed as there was no more collection in the subdural space. We reviewed the literature and discussed the pathophysiology involved in the development of intraabdominal complications following VPS.
