Dural arteriovenous fistulae after forehead knife-cut injury.
Dural arteriovenous fistulae (DAVF) is a rare intracranial vascular disease. It is pathologically characterized by direct shunting of the intracranial artery and vein, which results in cerebral ischemia, intracranial hemorrhage, neural deficit and intracranial murmur. The etiological mechanism of DAVF is not well known, but most researchers think it is associated with congenital abnormal development, especially abnormal development of dural blood vessels at the stage of embryogenesis. Recently, some researchers have found that DAVF is also associated with some acquired factors. This article reports a case who developed DAVF within 2 years after debridement of frontal bone fragmentation, depressed fracture, left frontal lobe contusion and superior sagittal sinus injury due to forehead knife-cut injury. The pathogenic mechanism was explored through a review of the related literatures.
