下肢动脉硬化闭塞症的腔内治疗

下肢动脉硬化闭塞症主要累及髂股动脉、股腘动脉和膝下动脉,目前主要的治疗方式是腔内治疗,由于三段动脉解剖的差异,其腔内治疗原则和效果是不同的.主髂动脉硬化闭塞的腔内治疗的通畅率不低于外科手术,已成为首选方式；股腘动脉硬化闭塞因其发病率高,腔内治疗的通畅率不能令人满意,已成为研究热点；膝下动脉闭塞的腔内治疗仍处在探索之中,...

Endovascular treatment of lower extremity atherosclerosis obliterans

Atherosclerosis obliterans of lower extremity artery mainly involve the aorto-lliac artery,femoral-popliteal artery and below-knee arteries.At present the major treatment of the disease is endovascular treatment.Due to anatomical differences between the three arteries,the principles and effect of endovascular treatment are different.The endovascular treatment of iliac- femoral lesions,because of its patency rate not lower than surgery,has become the preferred way.On account of the high incidence of femoral- popliteal lesions and the dissatisfaction for patency rate,the endovascular treatment of femoral-popliteal lesions has become a hot research.Endovascular therapy in the below-knee arteries is still in the exploration,currently a small balloon-based.
