Abstract：
UNASSIGNED: Interventional embolization schedules based on absolute ethanol are usually used for peripheral arteriovenous malformations (PAVMs), and clinicians often choose the scheme according to the classification.
UNASSIGNED: To evaluate different interventional embolization schedules based on absolute ethanol for PAVMs.
UNASSIGNED: A retrospective study was performed of 165 patients with PAVMs treated with interventional embolization based on absolute ethanol in Henan Provincial People\'s Hospital from January 2018 to May 2021. PAVMs were classified as type II (n = 67), type III (n = 81) and type IV (n = 17) according to the Yakes classification system, including 123 maxillofacial, 13 trunk and 29 limbs. Effectiveness of embolization was based on PAVM devascularization on angiography: 100% (total), 90%~99% (near-total), 70%~90% (substantial), 30%~70% (partial) and 0%~30% (failure).
UNASSIGNED: PAVMs were classified as type II (n = 67), type III (n = 81) and type IV (n = 17) according to the Yakes classification system, including 123 maxillofacial (74.55%), 13 trunk (7.88%) and 29 limbs (17.58%). There are statistical differences in the angiographic outcomes among different Yakes classification and between different methods (P < 0.05), and there was a statistical difference in the failure rates among different Yakes classification (P < 0.05).
UNASSIGNED: PAVMs occur maxillofacial usually, and Type II can achieve better effect by spring coil and absolute ethanol, while Type III and Type IV have no ideal effect by Pingyangmycin + iodized oil + PVA + absolute ethanol and spring coil + absolute ethanol, respectively. Both the two happen to be complications, and wound accounts the highest.

摘要：
■基于无水乙醇的介入栓塞方案通常用于外周动静脉畸形（PAVMs），临床医生往往根据分类选择方案。
■评价不同无水乙醇介入栓塞治疗PAVMs的方案
■回顾性研究河南省人民医院2018年1月至2021年5月165例无水乙醇介入栓塞治疗PAVMs患者。PAVM被分类为II型(n=67)，根据Yakes分类系统，III型(n=81)和IV型(n=17)，包括123个颌面，13个躯干和29个肢体。栓塞的有效性是基于血管造影的PAVM断流术：100％（总），90%~99%(接近总量),70%~90%(实质性)，30%~70%(部分)和0%~30%(失效)。
■PAVM被分类为II型（n=67），根据Yakes分类系统，III型(n=81)和IV型(n=17)，其中颌面123人(74.55%),躯干13例（7.88%），四肢29例（17.58%）。不同Yakes分级和不同方法间的血管造影结果差异有统计学意义(P<0.05),不同Yakes分级的故障率差异有统计学意义(P<0.05)。
■PAVM通常出现在颌面部，和II型可以通过弹簧线圈和无水乙醇达到更好的效果，而平阳霉素+碘化油+PVA+无水乙醇和弹簧圈+无水乙醇的III型和IV型效果不理想，分别。两者恰好都是并发症，伤口账户最高。
