An arteriovenous malformation is defined as a congenital lesion of dysplastic vascular origin with large feeding arteries causing decreased vascular resistance. Previously, initial attempts toward treatment by complete excision of the vascular mass were complicated by hemorrhage and infection. Cardiac failure and abnormal growth may result from the shunted blood flow. With the advancement of angiography, more defined study of the arteriovenous anomaly can be identified and a reduction of risk during treatment can be promised. Three cases of extensive arteriovenous malformations are presented. Each has been successfully treated by combining radiologic microembolization followed by surgical extirpation of the vascular mass, without complication.
动静脉畸形被定义为一种起源于发育异常血管的先天性病变，有粗大的供血动脉，导致血管阻力降低。以前，试图通过完全切除血管团来进行治疗，却因出血和感染而变得复杂。分流的血流可能导致心力衰竭和异常生长。随着血管造影技术的进步，可以对动静脉畸形进行更明确的研究，并有望降低治疗风险。本文介绍了三例广泛的动静脉畸形病例。每例均通过先进行放射学微栓塞，然后手术切除血管团的联合治疗而成功治愈，且无并发症。
