下肢缺血的腔内治疗现状

髂动脉狭窄闭塞的腔内治疗应用最多,成功率最高,技术最普及。经皮腔内血管成形术(PTA)和支架在股腘动脉狭窄闭塞治疗方面的应用还处于开发阶段。尽管股浅动脉腔内治疗的中远期通畅率低于手术转流,但其具有微创性和可重复的优势。腘动脉狭窄的治疗应采取谨慎态度。对小腿动脉狭窄闭塞的中远期疗效还缺少多中心前瞻性研究结果,但因其可解决部分患者糖尿病足长期不愈的痛苦,故有一定的临床应用价值。

Endovascular treatment of lower limb ischemia

Endovascular technique has been successfully and widely used in the treatment of iliac artery occlusion. The clinical values of percutaneous transluminal angioplasty (PTA) and stenting are still under investigation. Although the endovascular treatment of femoral and popliteal arteries has lower mid-and long-term patency rates than that of by-pass operation, its minimal invasiveness and easy repeatability are still encouraging. The decision of the endovascular treatment of popliteal artery should be made in a prudent manner. Its mid-and long-term efficacy on the treatment of lower extremities still lacks data from multi-center and prospective studies. However, considering its effectiveness in alleviating the pain suffered by patients with persisting diabetic feet, it can still be used in clinical practice.
