title: Abdominal pseudocysts complicating CSF shunting in infants and children. Report of 18 cases.
abstract: Abdominal pseudocysts (APC) are rare complications of ventriculoperitoneal shunting for hydrocephalus. The authors studied retrospectively a series of 18 pediatric patients with APC. Signs and symptoms of shunt dysfunction were observed in 15 (83.3%), abdominal complaints in 10 (55.5%) and fever in 6 (33.3%). Prior to the diagnosis of APC, 2 patients suffered exploratory laparotomies due to important abdominal signs and symptoms. Ultrasonography was diagnostic in all cases and proved to be the method of choice in the evaluation of APC. Our series suggest that APC are strongly related to hardware infection and in some cases can result from a previous shunt infection not completely cured. The bacteriological examination of the tip of the peritoneal catheter was a reliable indicator of infection. According to our data, the best treatment seems to be the removal of the shunt system and the insertion of an external ventricular drainage. In our experience, almost half of the patients had a ventriculoatrial shunt replacing the peritoneal shunt at the end of the treatment.
