股浅动脉首期置入自膨式支架与球囊扩张成形的疗效比较

Objective To compare the mid-term clinical results of primary implantation of a selfexpanding nitinol stent and primary percutaneous transluminal angioplasty (PTA) for long range arteriosclerosis obliterans of the superficial femoral artery. Methods From December 2005 to February 2007,109 patients who had moderate-severe claudication or chronic limb ischemia (CLI)due to stenosis or occlusion of the superficial femoral artery were treated by endovascular technology. 53 patients (73 limbs) were treated by primary stenting and 56 patients (76 limbs)by PTA. We compared the clinical data of stenting group and PTA group at 6,12 and 24 months. Results The mean length of the treated segment was (16± 8)cm in the stenting group and(15±7)cm in the PTA group. At 6 months, the rate of restenosis on duplex ultrasonography was 13.7% in stenting group and 30.2% in PTA group (X2=4.09, P<0.05);at 12 months the restenosis rates were 25.5% in stenting group and 46.9% in PTA group(X2=4.75, P<0.05);at 24 months the restenosis rates on duplex ultrasonography were 38.1% in stenting group and 65.9% in PTA group(X2=6.66, P<0.01). Rutherford stages in stenting group were significantly better than those in PTA group. Conclusion In the mid-term, primary implantation of a self-expanding nitinol stent yielded results that were superior to those with PTA for arteriosclerosis obliterans or long range stenosis of the superficial femoral artery.

踝肱指数在周围动脉疾病中的应用

<正>周围动脉疾病(peripheral arterial disease,PAD)是一种常见病,大约占总人口数12%～14%的人群受到累及,但同时大部分PAD患者是无症状的,因而未能早期发现和接受有效的治疗[1]。踝肱指数(ankle brachial index,ABI)是诊断PAD一种有效、无创的手段[2]。同时,ABI异常也是动脉粥

血管腔内治疗脑梗死合并下肢严重缺血的探讨

目的 观察血管腔内治疗脑梗死患者合并下肢严重缺血病变的技术成功率和临床疗效。方法 回顾性地分析2008年1月至2014年12月期间收治的Fontaine分级Ⅲ～Ⅳ级脑梗死伴肢体活动障碍患者280例（326条患肢）,采用以血管腔内治疗为主治疗。观察技术成功率、并发症、临床疗效、踝/肱指数（ABI）、治疗血管再狭窄等。结果 280例患者（326条患肢）共进行342次血管腔内治疗,309条患肢治疗成功,技术成功率为94.8%（309/326）,无严重并发症。患者手术成功后临床症状均明显改善。术前所有患者ABI为0.26±0.24,成功治疗术后ABI为0.72±0.29,手术前后患者ABI差异有统计学意义（P＜0.05）。共有210例患者（242条患肢）经术后＞6个月随访,平均随访27个月（3～90个月）,术后6个月、12个月ABI分别为0.65±0.26、0.54±0.31,均较术前显著增加;超声检查示术后1年随访期间有87条患肢（35.9%）治疗血管再狭窄或闭塞,其中70例（28.9%）症状复发再次行血管腔内治疗。结论 下肢动脉病变行血管腔内治疗手术技术成功率较高、并发症发生率较低、疗效确切,可作为下肢动脉病变的首选治疗;由于脑梗死肢体活动障碍患者术后功能锻炼受限,血管再狭窄发生率较高,需进一步研究以提高闭塞性病变的手术成功率和术后治疗血管的通畅率。
