Abstract:
Objective To evaluate the clinical effects of endovascular angioplasty and stenting for the treatment of TASC B,C arteriosclerotic occlusion(ASO) of lower extremity.Methods After the identification of the occlusion by angiography via femoral artery access by Seldinger method,the occluded arteries (mean length 7.5cm; range 1~20 cm) in 40 patients(47limbs) were treated by percutaneous transluminal angioplasty and stent placement. Results The primary recanalization was successful in 45 of 47 limbs. The technical successful rate was 96%. Thirty one self-expanding stents were deployed. PTA without stent placememt was performed in 16 limbs(of them,11 were blow knee).The ankle brachial pressure index (ABI) increased from (0.36?0.14) preoperatively to (0.82?0.15) on the 7th postoperative day. All patients were follow-uped for 1 to 48 months. Stents were occluded in 4 patients. Restenosis was observed in 1 limbs. All of the rest remained patent in the follow-up period.Conclusion Endovascular angioplasty and stenting can be an effective method for the treatment of long segmental (including below-knee) arteriosclerotic occlusion of lower extremities.
