目的 探讨硬脊膜动静脉瘘血液动力学改变的血管造影表现。方法 回顾性分析 2 8例硬脊膜动静脉瘘的选择性血管造影与栓塞治疗资料 ,所有患者均行全脊髓动脉血管造影检查。结果 2 8例硬脊膜动静脉瘘经血管造影检齐均能明确诊断 ,能显示病变的范围、血供情况及其特征 ,其特点为硬脊膜动脉与脊髓表面静脉直接相通。 18例 (6 4 3% )硬脊膜动静脉瘘位于脊柱左侧 ,10例 (35 7% )位于右侧 ,2 3例瘘口 (82 1% )位于胸 3与腰 2椎体平面之间。经超选择插管后 17例患者接受了栓塞治疗 ,其中 12例行栓塞后手术切除 ,随访观察见患者临床症状改善者 11例 (6 4 7% ) ,病情稳定者 4例 (2 3 5 % ) ,病情加重者 2例 (11 8% )。所有栓塞病例均无严重并发症发生。结论 血管造影是反映硬脊膜动静脉瘘血液动力学改变的重要手段。
Objective To investigate the hemodynamic changes of dural arteriovenous fistulas. Methods A retrospective analysis of 28 cases of spinal dural arteriovenous fistula selective angiography and embolization treatment data, all patients underwent whole-necked arterial angiography. Results 28 cases of spinal dural arteriovenous fistula angiography can be a clear diagnosis, can show the extent of the lesion, blood supply and its characteristics, which is characterized by direct communication of the spinal dura arterioles and spinal veins. Eighteen cases (64.3%) of spinal dural arteriovenous fistula were located on the left side of the spine, 10 cases (35.7%) were located on the right side, and 23 cases (82.1%) were located on the chest 3 and lumbar 2 plane between. Seventeen patients underwent transcatheter embolization after superselective intubation, of whom 12 underwent surgical resection after embolization. Eleven patients (64.7%) showed improvement in clinical symptoms, 4 patients (23.5% ), Two cases of exacerbations (11 8%). No serious complications occurred in all embolism cases. Conclusion Angiography is an important means to reflect the hemodynamic changes of arteriovenous fistula.
