Popliteal vein aneurysm (PVAs), though uncommon, can be a cause of pulmonary emboli. They can also result in pulmonary vein embolism despite the use of anticoagulation therapy. We report the case of an otherwise fit, 64-year-old male who had a history of sudden onset of dyspnea on exercise with near syncope. A computed tomography pulmonary angiogram confirmed filling defects in the lung bases in keeping with pulmonary emboli. He was anticoagulated and a venous duplex scan revealed a fusiform suprageniculate PVA with no evidence of thrombus in the lumen. He underwent resection of the aneurysm with lateral vein patch graft repair and was placed on anticoagulation for 6 months with no recurrence after 2 years of follow-up. PVAs are rare and can either be symptomatic or asymptomatic. We advise early surgical treatment to prevent the significant morbidity and mortality associated with thromboembolization. Written consent was obtained from the patient for publication of case and use of images.
腘静脉动脉瘤（PVAs）虽不常见，但可导致肺栓塞。尽管使用了抗凝治疗，它们仍可导致肺静脉栓塞。我们报告一例64岁健康男性病例，该患者有运动时突发呼吸困难伴接近晕厥的病史。计算机断层扫描肺动脉造影证实肺底部有充盈缺损，符合肺栓塞表现。他接受了抗凝治疗，静脉双功扫描显示为膝上型梭形腘静脉动脉瘤，管腔内无血栓形成迹象。他接受了动脉瘤切除术及外侧静脉补片移植修复术，并接受了6个月的抗凝治疗，随访2年无复发。腘静脉动脉瘤很罕见，可表现为有症状或无症状。我们建议早期手术治疗，以预防与血栓栓塞相关的严重发病率和死亡率。已获得患者书面同意发表该病例及使用图像。
