Isolated external iliac vein compression syndrome is an uncommon cause of nonthrombotic venous stenosis that causes chronic venous hypertension leading to painful swelling, skin discoloration, and ulcer formation. We present a case of an 86-year old man with refractory lower extremity edema for several years who had been treated with diuretics and antibiotics without relief of symptoms. With the help of invasive and noninvasive imaging modalities, we were able to diagnose and manage isolated nonthrombotic left external iliac vein stenosis as a result of ipsilateral external iliac artery compression.

孤立性髂外静脉压迫综合征一例及先进成像的作用

孤立性髂外静脉压迫综合征是非血栓性静脉狭窄的罕见原因，可导致慢性静脉高压，导致疼痛性肿胀、皮肤变色和溃疡形成。我们介绍了一例患有顽固性下肢水肿数年的 86 岁男性，他接受了利尿剂和抗生素治疗，但症状没有缓解。在侵入性和非侵入性成像方式的帮助下，我们能够诊断和处理由于同侧髂外动脉受压导致的孤立性非血栓性左侧髂外静脉狭窄。
