A Case of Dural Arteriovenous Fistulae with Unconsciousness and Hemiplegia after Surgery

A 50-year-old male underwent pancreatduodenectomy under general anesthesia without any problems. When he stood up from his bed on the third postoperative day, he lost consciousness and went into cardiac arrest suddenly. His heart beat recovered after resuscitation in the intensive care unit, but he was left with left hemiplegia. Pulmonary embolism was neglected by pulmonary blood flow scintigraphy. Cerebral angiography showed dural arteriovenous fistulae (DAVF) from the bilatered ophthalmic arteries to the right extradural vein and the occulusion at the sinus sagittalis superior, and a CT scan showed swelling of the right frontal lobe. In conclusion, it is better to pay attention to DAVF and sinus occlusion as a cerebrovascular complication after surgery.
