Cystic adventitial disease (CAD) is a rare vascular disorder predominantly seen in adults without cardiovascular risk factors. We report a case of CAD involving the common femoral vein in a 38-year-old female presented with right lower extremity swelling that was initially misdiagnosed as deep vein thrombosis (DVT). A computed tomography revealed a cystic structure that compressed the right common femoral vein with resultant severe stenosis of the vascular lumen. Complete evacuation of the cyst with excision of the cyst wall was performed, and the patient remained symptom-free at 3 year follow-up. This case highlighted that the rare venous CAD should be incorporated in the differential diagnosis of unilateral lower extremity swelling suspicious for a DVT. Complete evacuation and surgical excision of the cyst often conferred favorable clinical outcome.
囊性血管外皮细胞瘤病（CAD）是一种罕见的血管疾病，主要发生于无心血管危险因素的成年人。我们报告了一例累及股总静脉的 CAD 病例，患者为 38 岁女性，表现为右下肢肿胀，最初误诊为深静脉血栓形成（DVT）。计算机断层扫描显示一个囊性结构压迫右股总静脉，导致血管腔严重狭窄。我们通过完全清除囊肿并切除囊壁来治疗，患者在 3 年随访时无任何症状。本病例强调了在单侧下肢肿胀疑似 DVT 的鉴别诊断中应考虑罕见的静脉 CAD。彻底清除和手术切除囊肿通常可获得良好的临床效果。
