Venous aneurysms of the lower limbs are rare, and those located in the popliteal area are the most described. Congenital anatomical variations have been reported but are also exceptional. They can affect both superficial and deep veins. The risk of thromboembolism is present in deep locations, particularly in the popliteal area or in venous drainage malformations. We report the case of a pulmonary embolism revealing a venous aneurysm involving an atypical drainage vein. The contribution of Doppler ultrasound, CT scan, MRI, and venous Doppler was crucial for establishing the diagnosis. Surgery is the treatment of choice, combining in our case aneurysmorrhaphy and anticoagulation, with good patency observed in follow-up controls.
下肢静脉瘤罕见，其中位于腘窝区域的最为常见。虽有先天性解剖变异的报道，但也极为罕见。它们可累及浅静脉和深静脉。深部静脉，尤其是腘窝区域或静脉引流畸形处存在血栓栓塞风险。我们报告一例因肺栓塞而发现累及非典型引流静脉的静脉瘤病例。多普勒超声、CT扫描、MRI及静脉多普勒检查对确诊至关重要。手术是首选治疗方法，在我们的病例中采用了动脉瘤缝合术并联合抗凝治疗，随访检查显示通畅情况良好。
