介入腔内治疗在下肢动脉硬化闭塞症的应用

目的探讨下肢动脉硬化闭塞症（LEASO）的介入腔内治疗。 方法收集37例LEASO患者，共进行40次手术，处理病变血管56支，其中狭窄病变39处（39/56，69.64%），闭塞病变17处（17/56，30.36%），其中髂动脉病变19处(19/56，33.93%)，股动脉病变30处(30/56，53.57%)，胫动脉病变7处(7/56，12.50%)。 结果支架植入6处，球囊成形（PTA）9处，PTA+支架植入38处，手术成功率为94.64%（53/56），术后30天内无死亡病例。手术成功病例术后临床症状明显改善或消失，术前踝肱指数（ABI）为0.35±0.05，术后明显升高(0.73±0.14，P<0.01)。 结论介入腔内治疗LEASO成功率高，安全可靠，可显著改善临床症状。

Application of interventional endovascular treatment for lower extremity arteriosclerosis occlusion

ObjectiveTo explore interventional endovascular treatment for lower extremity arteriosclerosis occlusion (LEASO). MethodsA total of 40 interventional operations were applied in 37 patients with LEASO. There were 56 vascular lesions, including 39 sclerotic lesions (39/56, 69.64%) and 17 occlusive lesions (17/56, 30.36%). There were 19 iliac lesions (19/56, 33.93%), 30 femoral lesions (30/56, 53.57%) and 7 tibial lesions (7/56, 12.50%). ResultsStents were applied in 6 lesions. Percutaneous transluminal angioplasty (PTA) was applied in 9 lesions. PTA combined with stents were applied in 38 lesions. The success rate of operation was 94.64% (53/56 ). No death occurred within 30 days after treatments. The symptoms of lower limb ischemia were palliated or vanished in operation successful patients. Pre-operation ankle brachial index (ABI) was 0.35±0.05, post-operation ABI increased to 0.73±0.14 (P<0.01). ConclusionsInterventional endovascular treatment has an high success rate, it is safe and effective for LEASO, and can significantly improve clinical symptoms.
