摘要
目的通过MDCT随访评估主动脉弓替换加支架象鼻术治疗Stanford A型主动脉夹层的效果及其术后并发症。方法回顾性分析98例患者共167次主动脉MDCT术后随访检查。结果 98例患者出现心包积液40例,胸腔积液69例,肺不张55例,升主动脉人工血管吻合口漏18例,主动脉弓部远端覆膜支架I型内漏10例,其中支架近端内漏7例、远端内漏3例,纵膈气肿6例,支架以远假腔血栓形成8 2例,死亡1例。升主动脉人工血管吻合口漏与支架I型内漏发生率间有统计学意义联系。结论主动脉弓替换加支架象鼻术能有效治疗Stanford A型主动脉夹层;MDCT可作为主动脉弓替换加支架象鼻术后随访的重要方法。
Obiective To evaluate the role of total arch replacement combined with stented elephant trunk implantation for Stanford type A aortic dissection by MDCT. Methods 98 patients, 167 MDCT results were retrospectively analyzed. Results After total arch replace- ment combined with stented elephant trunk implantation, pericardial effusion（n=40）, pleural effusion（n=69）, atelectasis（n=55）, stomal leak of ascending aorta（n=18）, type l endoleak of stent（n= 10）,including endoleak of proximal stent（n=7） and endoleak ot distal stent（n=3）, mediastinal emphasema（n=6）, thrombosis of residual false lumen（n=82）, death（n=1） were observed. Significant relationships between incidences of stomal leak and endoleak of stent were found. Conclusion Total arch replacement combined with stented elephant trunk implantation is effective for Stanford type A aortic dissection. MDCT is an important method to evaluate postoperative changes of total arch replacement combined with stented elephant trunk implantation.
