Abstract：Objective:To investigate the approaches, nodi, therapies of complications and prognosis of endovascular treatment for patients with infrapopliteal arteries arteriosclerosis obliterians (ASO). Methods:We conducted endovascular treatment for 72 patients (84 limbs) between January 2008 and December 2012 and punctured femoral artery antegrade or retrograde, made lower extremity artery angiography, then used guide wire and catheter getting through the artery stenosis or occlusion. If failed, subintimal angioplasty was tried. Balloon was introduced with guiding wire to dilatating the vascular. After expansion, artery angiography was made to evaluate if there existed residual stenosis, when residual stenosis was greater than 30%, tried again. If arterial dissection occurred, drug-coated stent was implanted.Results:84 limbs underwent endovascular treatment and 82 achieved angiographic success with 97.6% clinical success rate. 16 cases with intermittent claudication increased claudicating distance of 500 m (50-2 500 m), resting pain of 43 cases lightened or disappeared, toe ulcer of 8 cases healed with dressing change after 3 months, 1 toe ulcer case autologous saphenous vein bypass because of in-stent thrombosis.3 cases with toe gangrene took operations and the wound healed in 3 months. 1 case with anterior half foot gangrene took below-knee amputation.Conclusions:Endovascular treatment is a safe and effective method for infrapopliteal arteries ASO, and which can be repeated, achieve a high clinical success rate with a low complication rate and a high limb salvage rate.
