Subintimal Angioplasty of Lengthy Femorotibial Total Occlusion in Buerger's Disease

Abstract

To report successful subintimal angioplasty of a lengthy femorotibial occlusion in a patient with Buerger's disease, with wound healing and limb salvage. A 38-year-old female heavy smoker was referred to our hospital for treatment of extensive infectious tissue loss, with severe foot pain 1 month after early failure of a distal bypass graft. Angiography revealed total occlusion in the femoropopliteal and infrapopliteal arteries. Endovascular recanalization was attempted in order to establish "straight-line flow" to the foot on the verge of limb loss. The subintimal angioplasty technique with a 0.014-inch hydrophilic guidewire facilitated successful crossing of the occlusive femoropopliteal and posterior tibial arteries. The lesions were serially dilated (standard and cutting balloons). Angiography demonstrated antegrade flow to the foot without flow-limiting dissection, and the serious pain dramatically disappeared. Complete wound healing was observed 5 months after initial revascularization with the assistance of repeat angioplasty for restenosis. Contemporary endovascular therapy using the subintimal angioplasty technique could represent a viable option for Buerger's disease.
