Primary patency rate of native vessel revascularization after failed femoropopliteal bypass surgery

Introduction
Treating patients with chronic limb-threating ischemia who have had failed femoropopliteal bypass represents a challenge, because these patients have TASC C or D lesions and may not be good candidates for surgical intervention. Endovascular intervention may offer a suitable solution.
Patients and methods
A retrospective case series of 34 patients presenting with chronic limb-threating ischemia and previously failed femoropopliteal bypass were subjected to native vessel revascularization through a contralateral approach with balloon dilatation and stenting on demand of the superficial femoral artery.
Results
Technical success was achieved in 91.18% of cases, stenting was done in 64.51% of cases, and the mean time for the procedure was 73.18±12.96 min. Ankle–brachial index significantly increased with clinical improvement. The patency rates at 3, 6, and 12 months were 80, 56.67, and 43.33%, respectively, whereas the limb-salvage rates at 3, 6, and 12 months were 96.67, 93.33, and 93.33%, respectively.
Conclusion
Native vessel revascularization is a feasible procedure that can be done safely with acceptable technical success and limb-salvage rate. It represents a good option for patients who are poor candidates for redo-surgery.
