Abstract

Arteriovenous malformations (AVMs) consist of abnormal communications between the arteries and veins. They can involve any part of the body and extremity and grow in proportion to age and in response to hormonal influence or trauma. When symptoms progress from Schöbinger clinical stage II to III, transcatheter and/or direct puncture embolization are less-invasive and repeatable options for symptom palliation. The goal of embolization is to obliterate the AV shunt, and the choice of lesion access and embolic agents is based on the individual anatomy and flow. Embolization can be technically challenging due to complex vascular anatomy and morbidity risks. Therefore, a multidisciplinary management is essential for the diagnosis and therapeutic intervention of AVMs.

血管内和经皮栓塞治疗身体和四肢动静脉畸形。

动静脉畸形(AVMs)是由动脉和静脉之间的异常通信组成的。它们可以涉及身体的任何部位和四肢，并与年龄成比例增长，并对激素影响或创伤作出反应。当症状从Schöbinger临床II期进展到III期时，经导管和/或直接穿刺栓塞是减轻症状的微创和可重复的选择。栓塞的目的是消除房室分流，病变通道和栓塞剂的选择是基于个体解剖和血流。由于复杂的血管解剖结构和发病率风险，栓塞在技术上具有挑战性。因此，多学科的管理对于AVMs的诊断和治疗干预至关重要。
