[PR-7-4] Preliminary Experience with Endovascular Therapy for Buerger’s Disease
キーワード：endovascular, TAO
Objectives: The aim of this retrospective study was to clarify the clinical outcome of endovascular therapy for Buerger's disease(Thromboangiitis obliterans: TAO) patients. Methods: This study included a total of consecutive 12 lower or upper limbs in 12 denovo patients(mean age, 46±11 years) undergoing endovascular therapy between April 2007 and May 2014. Procedural success was defined as revascularization of at least one occlusive segment without 30％ or more residual stenosis. Clinical success was defined as relief of ischemic pain, wound cure, avoidance of major amputation or improvement of claudication. Results: Clinical indications for revascularization were as follows; 6 instances of tissue loss in the lower extremity, 2 of tissue loss in the finger, and 4 calf claudication. Successful revascularization was achieved in all limbs. During a mean follow-up of 13±13 months(range, 1-48), clinical success was achieved in all cases, although 3 limbs required clinically driven repeat intervention for significant restenosis. There have been no deaths or major amputation. Conclusions: This preliminary experience with endovascular therapy produced a satisfactory clinical outcome in selected TAO patients. This novel approach might offer hope concerning the relief of pain, avoidance of major amputation, wound healing and improvement in quality of life.
