A scrotal arteriovenous malformation (AVM) is a rare condition representing an abnormal connection between the arterial and venous systems of vessels supplying the scrotum. Scrotal AVMs are usually treated via transcatheter embolization, surgical extirpation, or a combination of the two approaches. A 41-year-old man developed a life-threatening hemorrhage from a scrotal AVM. After hemodynamic stability was attained, multiple transcatheter embolization procedures were performed (over the course of several months) to eliminate blood flow through the AVM. Traditional embolic agents including microcoils, Embospheres®, and Gelfoam® were used, with only temporary reduction of blood flow through the AVM. Onyx®, a liquid embolic agent, was used successfully as an adjunct treatment to achieve blood flow cessation. Onyx® demonstrates efficacy in the treatment of scrotal AVMs, and is a viable alternative to traditional embolic agents.
阴囊动静脉畸形（AVM）是一种罕见病症，表现为供应阴囊的血管动静脉系统之间的异常连接。阴囊AVM通常通过经导管栓塞、手术切除或两种方法联合治疗。一名41岁男性因阴囊AVM发生危及生命的出血。在实现血流动力学稳定后，进行了多次经导管栓塞手术（历时数月）以消除通过AVM的血流。使用了包括微线圈、Embospheres®和明胶海绵®在内的传统栓塞剂，仅使通过AVM的血流暂时减少。液体栓塞剂Onyx®成功用作辅助治疗以实现血流停止。Onyx®在治疗阴囊AVM方面显示出疗效，并且是传统栓塞剂的可行替代方案。
