目的 加深对脑动静脉畸形 (AVM )数字减影血管造影 (DSA)表现特点的认识 ,并探讨其血管内栓塞治疗价值。方法 回顾性分析 98例脑动静脉畸形的血管内介入诊疗资料。结果 DSA均可显示供血动脉、畸形血管团和引流静脉 ,获得明确的诊断。 98例脑AVM中病灶最大直径 4 .0cm以下者 5 7例 ,位于深部 4 6例 ,单支供血动脉 17例 ,深部引流 16例 ,单支引流静脉 37例 (P <0 .0 5 )。 5 2例栓塞治疗的技术成功率为 10 0 % ,单纯真丝线段栓塞 36例 ,真丝线段和NBCA联合栓塞 16例。栓塞程度 :畸形血管团完全消失者 12例 ,畸形血管团减少 75 %以上者 2 1例 ,畸形血管团减少在 5 0 %～ 74 %之间者 11例 ,畸形血管团缩小不足 5 0 %者 8例。结论 DSA检查是脑动静脉畸形可靠的诊断方法 ,有利于估计其预后并制订治疗方案 ,血管内栓塞治疗是其安全有效的治疗手段
Objective To understand the characteristics of digital subtraction angiography (DSA) of cerebral arteriovenous malformation (AVM) and to explore the value of endovascular embolization. Methods A retrospective analysis of 98 cases of cerebral arteriovenous malformations of endovascular interventional data. Results DSA can show the blood supply artery, abnormal blood vessels and drainage veins, access to a clear diagnosis. 98 cases of brain AVM lesions in the largest diameter less than 4. 0cm 57 cases, located in the deep 46 cases, 17 cases of single feeding artery, deep drainage in 16 cases, 37 cases of single drainage veins (P <0. The technical success rate of 50 cases of embolization was 100%. There were 36 cases of pure silk segment embolism, 16 cases of silk segment and NBCA embolization. The degree of embolism: 12 cases of complete disappearance of vascular malformation group, 21 cases of abnormal vascular group reduced by 75% or more, 11 cases of deformity vascular reduction in 50% ~ 74%, less than 50% deformity vascular mass 8 cases. Conclusions DSA is a reliable diagnostic method of cerebral arteriovenous malformations, which is good for estimating the prognosis and developing the treatment plan. Endovascular embolization is a safe and effective treatment
