[Peritoneal pseudocysts: complications of ventriculo-peritoneal shunts. Apropos of 3 cases]

From 1975 to 1995, 335 patients were operated for hydrocephalus in neurosurgical clinic of CHU Fann, and got ventriculo-peritoneal shunt. 3 cases of patients presenting an uncommon complication of ventriculo-peritoneal shunt: abdominal pseudo cyst, are reported and discussed. The digestive symptoms are the first to manifest themselves for a period of time, then confusing with other forms of abdominal cysts. The suggested treatment is to remove the shunt from the peritoneal cavity and perform a ventriculo-atrial shunt, then to proceed to a laparotomy, drain the fluid and resect the cyst wall. The results are excellent.
