[Postprandial and postural dyspnea: a clinical sign of intraperitoneal pseudocyst in patients with hydrocephalus and ventriculo-peritoneal shunt].
The surgical treatment of hydrocephalus has been greatly improved by the techniques of ventriculo-peritoneal shunting. Several complications may however occur following these operative procedures. Most of the complications are related to the distal end of the shunt device and include obstruction of intraperitoneal catheter, development of inguinal hernia or hydrocele, perforation of viscera. Many observations have been dedicated to these pathological findings, due to their frequency and the relatively easy diagnosis. Intraperitoneal pseudocysts are also a known complication of ventriculo-peritoneal shunts. Owing to their relative rare incidence and the aspecificity of their clinical presentation, this last type of complication has received a minor consideration. In the present report the authors describe two cases of intraperitoneal pseudocysts clinically manifested by the occurrence of postprandial dyspnea and hiccupping, without any apparent sign of CSF shunt device dysfunction.
