目的观察TASCⅡ C、D型股腘动脉闭塞腔内治疗的临床疗效,分析影响治疗效果的可能因素与操作技巧。方法 2009年1月～2010年6月,89例(113条患肢)TASCⅡ C、D型股腘动脉闭塞患者接受腔内治疗。对患者术后3、6和12个月时的临床症状、踝肱指数(ABI)、并发症发生率和累计通畅率进行分析。结果成功开通病变肢体共106条,技术成功率93.8%。36条(34.0%)患肢出现并发症。75例患者(共92条下肢)获得随访,随访率为86.8%。平均随访时间12.5个月。术后3、6和12个月时的平均ABI分别为0.74±0.39、0.68±0.38和0.66±0.31,与术前比较(0.43±0.39),差异均有统计学意义(P<0.01)。术后12个月的一期通畅率、辅助通畅率和二期通畅率分别为64.6%、72.4%和81.5%。结论 TASCⅡ C、D型股腘动脉闭塞腔内治疗是一种安全有效的方法。熟练的腔内操作技术和规范的术后指导是提高技术成功率和维持动脉早中期通畅的关键。     

内膜下血管成形术治疗下肢动脉慢性缺血

Objective To assess the technical feasibility, patency and outcomes of subintimal angioplasty (SIA) for treatment of the lower extremity arteriosclerosis occlusions. Methods During the period from December 2003 to August 2008, 122 lower extremities with arteriosclerosis occlusions (median length, 10.25 cm;range, 4.5 to 28 cm) were treated on an intention-to-cure basis with SIA. Twenty-three lower extremities had disabling claudication and ninety-nine had limb-threatening ischemia. Patient history, demographics, procedural details, complications, and follow-up information were collected and analyzed. Patency, limb salvage, sustained improvement in claudication was determined by Kaplan-Meier analysis. Results The technical success rate of SIA was 83%. Following successful SIA, the mean ankle-brachial index increased from 0.19±0.11 to 0.67±0.29 (P<0.01). Primary patency at 12 and 24 months was 54%±5% and 45%±4% respectively, the clinical effective rates (rates of limb salvage and improvement in claudication) at 12 and 24 months were 82%±5% and 79%±4% respectively. No serious complications occurred. Conclusion In a selected group of patients, SIA is feasible with a high technical success rate and the clinical effective rates are satisfactory, there were no severe complications. SIA is a good treatment alternative in patients suffering from chronic ischemia with arteriosclerosis occlusions in the lower extremity.

动脉重建术后再狭窄相关miRNA表达谱分析及靶基因鉴定

目的 筛查动脉粥样硬化闭塞症( ASO)血管重建术后再狭窄相关miRNA基因表达谱,分析并鉴定表达差异显著的miRNA及其潜在靶基因.方法 取下肢ASO患者股动脉标本6例,3例未行血管重建术(A组),3例动脉重建术后再狭窄(R组),另取正常股动脉3例为正常对照(N组).利用miRNA基因芯片检测miRNA差异表达谱,以实时逆转录-聚合酶链反应(real-time RT-PCR)验证其表达,并通过构建双荧光素酶报告基因系统鉴定预测靶基因.结果 与N组比较,病变组(A组+R组)miRNA-1和miRNA-335表达下调,没有miRNA表达上调;R组miRNA-623表达上调,17个miRNAs下调;A组miRNA-1和miRNA-335表达下调,没有miRNA表达上调.与A组比较,R组17个miRNAs上调,9个miRNAs下调.表达下调以miRNA-1最显著,并经real-time RT-PCR证实(P＜0.05).双荧光素酶实验证实miRNA-1靶向抑制Kruppel样因子4(KLF4)的表达(P＜0.05).结论 miRNA可能参与ASO及动脉重建术后再狭窄的发病机制,其中miRNA-1可能起重要作用.
