1 Objectives To evaluate short-term results of subintimal angioplasty for long-segment total occlusion of superficial femoral artery.

2 Objective To explore the safety and validity of subintimal angioplasty(SIA)for the superficial femoral artery occlusions in the lower extremities.

3 ABSTRACT:Objective To assess the value of subintimal angioplasty in treating patients with iliac artery occlusive disease.

4 Objective To explore the method and effectiveness of subintimal angioplasty (SIA) combined with percutaneous transluminal angioplasty (PTA) for total occlusion of iliac artery.

5 On 3rd day after balloon injury, a small amount of new endothelial cells were high columnar and nuclear were stain with subintimal bleeding and elastic membrane disruption.

6 Methods Clinical data of 3 patients with superficial femoral artery long-segment total occlusion and technique of subintimal angioplasty were retrospectively analyzed.

7 After SIA for the occluded artery segment, balloon angioplasty of the subintimal space and stents were released (18 naked stents, 4 PTFE-covered stents).
