Repeated Pseudoaneurysm after Endovascular Repair of Popliteal Aneurysm due to Graft Disintegration and Fabric Tear

Endovascular repair of popliteal artery aneurysms (PAA) using a stent graft is suitable for patients with favorable anatomy. In the domestic situation where Gore Medical withdrew, we report two cases of unusual complications of pseudoaneurysm after endovascular repair of PAA. A 44-year-old male with a history of bypass surgery for a PAA presented with recurrent vein graft pseudoaneurysm. Endovascular treatment using a domestic stent graft was performed. However, pseudoaneurysm developed due to the graft fabric tear 1 month later, requiring surgical removal. In another case, an 84-year-old female presented with acute limb ischemia related to PAA. Endovascular aneurysm repair with the same domestic stent graft was performed. However, stent graft failure occurred 2 years later and the patient underwent open surgical repair. There was a graft fabric disintegration. When proper endovascular device is not available, open surgical treatment is the best option for treating PAA
