目的：提出一种改进的外周动静脉畸形（AVMs）的血管造影分类方法，并确定其对评估治疗效果和乙醇栓塞身体和四肢动静脉畸形的方法的价值。方法：根据病灶的血管造影形态将躯干和四肢的动静脉瘘分为I型（动静脉瘘）、II型（动静脉瘘）、IIIa型（动静脉瘘未扩张）、IIIb型（动静脉瘘合并扩张）。回顾性分析66例（41名女性，平均年龄28.3岁，范围5-53岁）身体和四肢不能手术的动静脉畸形患者，他们接受了分期乙醇栓塞治疗。根据上述分类系统对治疗效果和方法进行评价。结果：66例avm中，IIIb型30例（45%），11型13例（20%），IIIa和IIIb混合型12例（18%），II和IIIb混合型9例（14%），IIIa型2例（3%）。乙醇栓塞对II型（100%）最有效，对IIIb型（83%）比IIIa型或混合型（83%）更有效。
Purpose: To propose a modified angiographic classification for peripheral arteriovenous malformations (AVMs) and to determine its value for assessing therapeutic outcomes and approaches to ethanol embolization of AVMs in the body and extremities.Methods:AVMs of the trunk and extremities were categorized according to the angiographic morphology of the nidus: type I (arteriovenous fistulae), type II (arteriolovenous fistulae), type IIIa (arteriolovenulous fistulae with non-dilated fistula), and type IIIb (arteriolovenulous fistulae with dilated fistula). Sixty-six patients (41 women; mean age 28.3 years, range 5-53) with inoperable AVMs in the body and extremities who underwent staged ethanol embolizations were retrospectively analyzed. Therapeutic outcomes and approaches were evaluated according the above classification system.Results: The 66 AVMs were composed of 30 (45%) type IIIb, 13 (20%) type 11, 12 (18%) mixed types IIIa and IIIb, 9 (14%) mixed types II and IIIb, and 2 (3%) type IIIa. Ethanol embolization was most effective for type II (100%), and more effective for type IIIb (83%) than for type IIIa or mixed types (
