摘要
本文报告５组不同原因所致的静脉高压共１９例，包括：（１）主要脊膜动静脉屡向脊髓表面引流６例；（２）髓周小动静脉瘘，伴有缓慢和迂曲的静脉扩张１例；（３）硬脑膜动静脉瘘向脊髓静脉引流５例；（４）Ｃｏｂｂ＇ｓ综合征伴有椎旁静脉直接引流，引起脊髓静脉流出道的间接高压６例；（５）硬脊膜外血管瘤向脊髓表面静脉引流１例。本文详述了机制及治疗方法。
Abstract This article reports 19 cases of spinal venous hypertension caused by different factors:( 1) 6 cases of spinal dural AVF draining to medullary veins ; (2) 1 case of perimedullary AVF with small fistula, slow blood flow and tortuous veins; (3) 5 cases of brain dural AVF draining to spinal veins; (4) 6 cases of Cobb's syndrome with paraspinal AVM draining directly to paraspinal veins; (5) 1 case of extradural angioma draining to spinal veins.When AVF drains to the spinal cord surface,either large volume of arterial blood to veins,or the veins themselves lack the ability to drain the blood out, both may give rise two results: one is venous pressure increase, the other is the blood of spinal parenchyma difficult to drain out and congestion and edema may occurred, the latter condition often gets worse by angiography. Once the lesion shows obvious deterioration , prompt embolization or operative clipping of fistula, These may bring the patients to get instant recovery. The specific methods of treatment and the mechanism of pathogenesis were also discussed.
