Abstract
Popliteal venous aneurysms (PVAs) are rare vascular anomalies that can result in serious thromboembolic complications. We present a case of a 77-year-old woman with a thrombosed right PVAs complicated by pulmonary embolism. Following initial anticoagulation, surgical resection of the aneurysm was performed, and individualized venous reconstruction was achieved using an autologous great saphenous vein (GSV) roll graft. This technique was selected over conventional panel or spiral grafts due to its simplicity, adaptability to size discrepancy, and reduced suture lines. To our knowledge, the use of a GSV roll graft, specifically tailored for popliteal vein reconstruction in thrombosed PVAs, has not been previously reported. Postoperative anticoagulation was continued with direct oral anticoagulants. Graft patency was confirmed by duplex ultrasonography and contrast-enhanced CT venography at regular intervals. At 1.5 years post-surgery, graft patency was maintained, and the patient remained symptom-free. This case highlights the effectiveness of individualized venous reconstruction using a GSV roll interposition graft in managing complex thrombosed PVAs.
