目的 探讨腔内介入治疗糖尿病病足的临床疗效。方法 以我科收治的52例糖尿病病足患者为研究对象，所有患者 在常规治疗上予以经皮腔内血管成形术(PTA)、支架植入等措施治疗，观察患者治疗后糖尿病足的改善情况。结 果 间歇性跛行总有效率92.0％，静息痛总有效率81.48％；坏疽溃疡总有效率84.62％；ABI及血管内径依次为 (0.94±0.26)、(2.05±0.31)cm，较治疗前显著上升(P<0.05)；且ABI分级明显优于治疗前；仅3例患者出现低血 糖，7例患者术后疼痛剧烈，经对症治疗后显著改善，均无其他严重并发症。结论 适时采取血管内球囊成形术或管 腔内支架植入术可有效改善糖尿病足患者临床症状，且具有较高的安全性，促进患者康复，临床疗效较好。

Objective To study the clinical effect of endovascular interventional treatment for diabetic foot. Methods A total of 52 patients with diabetic foot in our hospital were taken as the clinical research objects, and percutaneous transluminal angioplasty ( PTA) , stent placement and other treatment measures were given to these patients. The improvement of diabetic foot in these patients after treatment were observed. Results The total effective rates of intermittent claudication, rest pain and necrotic ulcer were respectively 92.0%, 81.48% and 84.62%. The ABI and vessel diameter were (0.94±0.26) and (2.05±0.31)cm which were significantly higher than those before treatment(P<0.05), and the ABI classification was significantly better than that before treatment. Only 3 patients had hypoglycemia and 7 patients had serve postoperative pain, and the symptoms of these patients were significantly improved after symptomatic treatment, and there were no other serious complications. Conclusion Timely balloon transluminal angioplasty or endovascular sent placement which has higher safety and better clinical effect, can effectively improve the clinical symptoms and promote rehabilitation of patients with diabetic foot
