摘　　要：目的分析健康血管锚定长度不足15 mm的Stanford B型主动脉夹层(TBAD)于不同时机释放Castor分支支架的主动脉重塑效果及与血栓形成的相关性。方法选取梅州市人民医院收治的46例择期释放Castor分支支架的患者,其中对照组于10~14 d治疗,研究组则于5~9 d治疗,观察不同时机释放Castor分支支架的疗效及与血栓形成的相关性。结果研究组部分血栓形成率为16.0%,较对照组降低(P<0.05);研究组血栓完全吸收率为84.0%,较对照组升高(P<0.05)。结论Castor分支支架具有隔绝性好、精准性高等优势,其中5~9 d释放更利于假腔血栓形成及吸收。Objective To analyze the aortic remodeling effect of Stanford type B aortic dissection(TBAD)with less than 15 mm anchorage length at different times of releasing castor branch stent and its correlation with thrombosis.Methods A total of 46 patients admitted to the hospital were selected for elective release of castor branch stent,with the control group receiving treatment in 10~14 days and the study group receiving treatment in 5~9 days,to observe the effect of release of castor branch stent at different times and the correlation with thrombosis.Results The partial thrombosis rate in the study group was 16.0%,lower than that in the control group(P<0.05).Total thrombus absorption in the study group was 84.0%,which was higher than that in the control group(P<0.05).Conclusion Castor branch stent has the advantages of good isolation and high accuracy,among which 5~9 days release is more conducive to the formation and absorption of false lumen thrombosis.
