摘要目的 探讨膝下动脉支架成形术治疗严重下肢缺血的安全性和有效性.方法 回顾性分析13例严重下肢缺血患者的临床资料.男10例,女3例,平均年龄(73±7)岁,平均病程(8±4)个月.下肢间歇性跛行5例,静息痛4例,足趾溃疡2例,坏疽2例.5例支架放于胫腓干动脉,3例于腓动脉近段,2例于胫腓干动脉和近段腓动脉,2例于胫前动脉,1例胫后动脉.2例为单纯小腿动脉支架成形,余11例患者均同时采用介入技术处理了股动脉和(或)胭动脉病变.结果 所有患者手术均获得成功.出院时所有患者再通血管保持通畅.跛行距离均增至500米以上,4例静息痛全部缓解,2例足趾溃疡面积均有所缩小,2例坏疽保持干燥出院,术后踝肱指数(ABI)均有增加.所有患者得到随访,平均随访时间(6.9±2.2)个月.l例下肢坏疽患者的症状6个月后复发(其胫前动脉支架仍然保持通畅)而截肢,坏疽的另外1例患者的第2趾脱落,创面愈合.2例溃疡面愈合,静息痛无复发.结论 膝下动脉支架成形术是治疗严重下肢缺血的安全有效方法.

abstractsObjective To explore the safety and feasibility of calf arterial stent angioplasty to treat severe lower limb ischemia. Methods Clinical data of 13 patients in our hospital during recent 3 years were retrospectively analysed and all these patients were followed up after discharge.Of these patients there were 10 males and 3 females; mean age was (73 ±7) years; mean disease course was (8 ±4) months.Severe claudication was reported in 5 patients,rest pain in 4 patients,toe ulcer in 2 patients,gangrene in 2 patients.Stent was placed in the tibioperoneal trunk artery in 5 patients ; in the proximal part of peroneal artery in 3 patients; in the tibioperoneal trunk and proximal peroneal artery in 2 patients; in the anterior tibial artery in 2 patients; in the posterior tibial artery in one patient.Simultaneous endovascular treatment of femoral/popliteal arterial disease was done in 11 patients. Results All the procedures were successful and the treated arteries kept patent on discharge of patients.Claudication distance increased to be above 500 meter in 5 patients; rest pain relieved in 4 patients ; toes ulcer reduced in 2 patients,feet gangrene kept dry till discharge in 2 patients.Postoperative ABI increased in all patients.Patients were followed-up of mean (6.9 ± 2.2) months.One patient with previous toe gangrene underwent amputation due to recurrent pain while the stent in anterior tibial artery kept patent after 6 months discharge.In the other patient gangrene toe had fallen off and the wound healed.Two patients with toe ulcer had a total recovery and patients with previous rest pain had no recurrent symptoms. Conclusions Below knee arterial stent angioplasty is a safe and effective method in the treatment of severe lower limb ischemia.
