糖尿病足患者膝以下动脉的介入治疗

Interventional therapy on below-knee arteries in patients with diabetic foot ulcers

糖尿病足血管病变范围广，膝以下血管以重度乃至完全闭塞病变为主，介入治疗后患肢血流改善明显，皮温及踝肱指数明显升高，溃疡愈合加快，间歇性跛行距离显著增加，经股动脉穿刺介入治疗近期疗效满意，可明显改善患肢血供。

The arterial lesions of lower extremities in patients with diabetic toot ulcers were extensive. The majority of below-knee arteries showed severe stenosis, even complete occlusion. Interventional therapy of femoral artery was effective in improving arterial blood perfusion and remission of the pain and numbness. After therapy, the skin temperature and ankle brachial index （ABI） were increased, healing of ulcer was enhanced and intermittent elaudieation was ameliorated. Percutaneous transluminal angioplasty of femoral artery was effective in improving arterial blood perfusion of the lower extremities with foreseen curing efficacy.
