复杂DeBakey III型夹层腔内隔绝术后1年的疗效及其影响因素

目的 观察和分析复杂DeBakey III型夹层行腔内隔绝术（TEVAR）后1年的疗效及其影响因素。方法 搜集2013年1月~2015年7月诊断DeBakey III型患者40例，术后随访1年,分为假腔内血栓完全形成组及部分形成组，两组行对比分析。结果 行多重线性回归分析，假腔内血栓形成与手术时间(B=-0.058,P=0.000)、多发破口(B=-0.031，P=0.032）呈线性相关。假腔内血栓完全形成与手术时间行Pearson分析(r=-0.731,P=0.000)。结论 DeBakey III型患者行TEVAR术后假腔内血栓形成与手术时机的选择、多发破口密切相关。

Analysis of 1-year effects and risk factors of endovascular repair for complicated DeBakey III aortic dissection

AIM To analyze the 1-year effects and risk factors of endovascular repair for complicated DeBakey III aortic dissection. METHODSForty patients underwent endovasccular repair from January 2013 to July 2015 and were divided into two groups (thrombus in full false-lumen and thrombus in partial false-lumen). The 40 patients were followed for 1 year and results were compared. RESULTSMultiple linear regression indicated thrombus in false-lumen was linear with surgical time (B=-0.058, P=0.000) and multiple tears (B=-0.031, P=0.032). Pearson analysis showed a negative correlation between thrombus in full false-lumen and surgical time r=-0.731, P=0.000). CONCLUSIONFor complicated Debakey III aortic dissection, surgical time is important for thrombus in full false-lumen after TEVAR.
