Clinical Of Drug-eluting Stent Versus Excimer Laser Ablation Combined Drug-coated Balloon To Treat Arteriosclerosis Occlusive Disease Of Lower Extremity

Prospective randomized controlled study to evaluate the difference of safety，effectiveness between Excimer Laser Ablation Combined Drug-coated Balloon and drug-eluting stent in treatment of femoral-popliteal artery lesions. Patients with femoral-popliteal artery lesions in our department were randomly assigned to the Excimer Laser Ablation Combined Drug-coated Balloon group and drug-eluting stent group. Compare the ischemic improvement rate (limb salvage rate, postoperative patency rate) and the complications rate of two different treatments. At the same time, the peri-operative related factors that may affect the end point events, such as preoperative baseline data, lesion characteristics, imaging features, stent fracture, and end point observation indexes were analyzed by regression analysis.
