Purpose: This study evaluates the feasibility of limb salvage revascularization of chronic total occlusion of native infrainguinal arteries in patients with chronically occluded lower limb bypass grafts.
Methods: A retrospective review of patients who underwent revascularization of native vasculature after failure of femoropopliteal bypass graft in critical limb ischemia. Age, gender, occluded vasculature, date and type of bypass surgery, date and method of revascularization were recorded. Technical success was assessed.
Results: Between the years 2014-2017, 13 patients and 14 limbs have undergone endovascular revascularization of the native femoropopliteal vasculature. In 14 of cases the native vessels were occluded for 86.4 months +- 73.8 months. The procedure was successful in all cases.
Conclusion: Revascularization of native vasculature after long standing occlusion is feasible and should be considered as a limb salvaging treatment option before amputation.
