Recent advance in interaction between acute subdural hematoma and disorder of intracranial superficial venous circulation

Traumatic acute subdural hematoma (ASDH) is often severe, and bridging vein rupture is one of the case mechanisms of ASDH. After traumatic ASDH, venous reflux disorder, cerebral ischemia, delayed bleeding in other parts of the brain, and intraoperative encephalocele are prone to occur. This article reviews the occurrence and development of ASDH and its relation with intracranial venous circulation. Key words: Acute subdural hematoma; Cortical vein; Bridging vein; Cerebral ischemia; Acute encephalocele
