Cerebral venous thrombosis after lumboperitoneal shunting: A case report.

Lumboperitoneal shunt (LPS) has been an effective treatment of idiopathic normal pressure hydrocephalus (iNPH) but sometimes causes serious complications. Here we present the first reported case of cerebral venous thrombosis (CVT) after LPS. A 76-year-old man underwent LPS for iNPH and a week later developed weakness of the right arm and a generalized tonic-clonic seizure. Brain computed tomography and magnetic resonance imaging showed bilateral subdural hematoma (SDH) and left cortical vein thrombosis. Intravenous heparin was administered, followed by surgical evacuation of the SDH. The patient experienced gradual improvement and was subsequently discharged. It is conceivable that overdrainage of cerebrospinal fluid led to the development of both SDH and CVT. CVT is potentially fatal and should be recognized early as a possible complication after LPS to allow prompt treatment.
