Objective: The aim of this study was to evaluate outcomes of combined popliteal-to-distal bypass and endovascular treatment (EVT) for femoropopliteal lesions in patients with critical limb ischemia (CLI).Patients and Methods: We reviewed data of 14 CLI patients who were treated by popliteal-to-distal bypass combined with femoropopliteal EVT. The femoropopliteal lesions included 3 TASC II-A, 8 TASC II-B, and 3TASC II-C but no TASC II-D, and balloon dilatation was performed in 9 cases and a stent was placed in 5 cases. The saphenous vein graft was used in all bypasses, and the target arteries were the dorsalis pedis artery in 12 cases and the posterior tibial artery in 2 cases.Results: At 12 and 24 months, primary patency rates were both 79%, primary assisted and secondary patency rates were both 93%, limb salvage rates were both 93%, and survival rates were 92% and 84%, respectively. Restenosis after femoropopliteal EVT occurred in 2 cases, and both were successfully revised by additional endovascular balloon dilatation.Conclusion: Combined popliteal-to-distal bypass and femoropopliteal EVT might be a useful therapeutic option for appropriately selected CLI patients. Intensive follow-up for endovascular treated lesions and vein graft is mandatory.
