Arteriovenous malformations (AVMs) are aggressive congenital high-flow vascular anomalies, in which the feeding artery and draining vein are connected through fistulas without normal capillary networks. In severe cases, the condition may cause swelling, ulceration, bleeding, and even heart failure. Various treatment options are available for AVMs, including laser, surgical resection, embolization, and targeted drug therapy. With the development of endovascular treatment technology, absolute ethanol embolization of AVMs has become one of the first-line therapies owing to its sustained efficacy and low recurrence rate. However, administration of this therapy is challenging and may lead to serious complications if inappropriately managed. In this article, we reviewed and summarized previous clinical articles, literature reviews, and clinical trial data to comprehensively describe clinical manifestations of AVMs, the mechanism of ethanol embolotherapy, key points in treatment and management of complications, and issues that need to be addressed. We expect to provide a reliable information reference source for clinical physicians and researchers. |
