Spontaneous extrusion of peritoneal catheter of ventriculoperitoneal shunt through the intact abdominal wall: Report of two cases.

Among the various complications associated with ventriculoperitoneal shunt (VPS) surgery, migration of the peritoneal catheter is one of the rarest complications. We report two cases of spontaneous extrusion of the peritoneal portion of the VPS through the intact abdominal wall at an area unrelated to the surgical incision. Both were conscious and had no neurological deficits.
