：2 型糖尿病的发病率逐年增高，下肢血管病变是其严重并发症之一，其临床特点主要有间歇性跋行、静息痛、缺血性坏疽等，严重者可发生肢端坏疽，一旦出现以上症状，治疗相当困难，甚至导致截肢。因此尽早发现并预防该并发症的发生，对于改善患者预后有着极重要的临床价值[1]。目前临床上对于2 型糖尿病下肢血管病变的评估方法众多，包括间歇性跛行、静息痛等临床表现，足部动脉搏动检查，踝- 肱血压指数，经皮氧分压检查, 彩色多普勒超声检查, CT 血管成像，MR 血管成像，数字减影血管造影等。在现今超声及影像设备和技术飞速发展的大背景下，本文对以上方法的价值、局限性及其最新研究进展作一综述。

英文摘要:

The incidence of type 2 diabetes increased year by year. One serious complications of diabetes is the lower extremity vascular disease, whose clinical features include intermittent postscript line, rest pain, ischemic gangrene and other serious cases like gangrene. Once the above symptoms appear, it is difficult to cure, and patients even have to suffer amputation. Therefore, early detection and prevention of the complication have vital clinical values in improving the prognosis of patients. At present, there are many methods to assess the lower extremity vascular disease of type 2 diabetes mellitus，including via the patients' clinical manifestations like intermittent claudication and rest pain, foot arterial pulse examination, ankle-brachial blood pressure index, transcutaneous PO2 checks, color and more Doppler ultrasound, CT angiography, MR angiography, digital subtraction angiography, and so on. Limitations and recent advances on the above methods are reviewed here in the present settings of rapidly development of ultrasound and imaging equipment and technology.
