摘　　要：下肢动脉狭窄-闭塞性病变影像学检查在明确病变类型和性质的同时,还需了解病变部位、范围、程度、分支及整个血循环状态,以便选择合理的治疗方案,指导治疗过程以及评估预后。目前,DSA仍是最为可靠的诊断工具,MRA和CTA可作为下肢动脉疑似病例的筛选性初步诊断方法,超声多用于随访复查。下肢动脉狭窄-闭塞性病变的治疗方法包括临床维护性治疗、溶栓、球囊扩张、支架、内旋切、激光治疗、取栓、内膜剥离、搭桥术、截肢等,各种方法对各种病变特点均有其明确的适应证,但更强调联合多种方法予以综合性治疗。The purposes of radiologic examination aimed at arterial stenosis - occlusion of lower extremities is not only for the qualitative analysis, but also for the diagnosis of definite location, distribution, blood circulation of foot, and, grade of diseases.At present, DSA is still the most reliable tools for the vascular diseases. MRA can be used as a filter method for the doubted cases. Ultrasonic examination mainly be served for follow up review. The therapeutics include conservative therapy, thrombolysis, balloon angioplasty, stent graft, rotational atherectomy, laser angioplasty, thrombectomy, endarterectomy, bypass graft, and, amputations. It has been emphasized that each method has its own therapeutic properties, but synthetic means must be introduced.
