Abstract

The etiology of arteriovenous (AV) malformations remains incompletely understood. Two cases of acquired AV malformations wholly located within the thrombosed lumen of the femoral and external iliac veins are presented here. The patients presented with symptoms of high venous pressure: pigmented skin and chronic pain. Such AV malformations have been rarely described in the extracranial circulation. The associated pain was successfully treated with catheter-based embolization of the lesions. The induction of the AV malformations in the peripheral circulatory system raises questions regarding the nature of angiogenesis and its possible triggers.

摘要

动静脉（AV）畸形的病因仍不完全清楚。本文介绍了 2 例完全位于股静脉和髂外静脉血栓腔内的获得性 AV 畸形。这些患者表现出静脉高压的症状：色素沉着的皮肤和慢性疼痛。这种 AV 畸形在外周循环中很少被描述。通过导管栓塞病变，成功地治疗了相关疼痛。外周循环系统中 AV 畸形的诱导引发了关于血管生成及其可能触发因素的性质的问题。
