A case is reported of a 66 year old woman presenting with perimesencephalic subarachnoid haemorrhage (SAH) which was caused by a spinal dural arteriovenous fistula at the C1 level. The fistula drained into the venous system of the posterior cranial fossa through a perimedullary vein. The bleeding was thought to result from venous hypertension induced by the fistula. This case may support the hypothesis that perimesencephalic non-aneurysmal SAH can be ascribed to venous bleeding and that venous hypertension is the key to its pathology.
报告了一例66岁女性,表现为中脑周围蛛网膜下腔出血(SAH),其由C1水平的脊髓硬脊膜动静脉瘘引起。该瘘通过髓周静脉引流至后颅窝静脉系统。出血被认为是由瘘引起的静脉高压所致。该病例可能支持以下假说,即中脑周围非动脉瘤性SAH可归因于静脉出血,且静脉高压是其病理关键。
