摘要
目的:评价多层螺旋计算机断层摄影术(MSCT)在主动脉夹层腔内隔绝术(EVE)后随访中的价值。方法:30例主动脉夹层患者于EVE前、后行MSCT检查,对比观察EVE前、后MSCT图像,分析真、假腔、重要分支及内支架等的变化。结果:30例患者,①真、假腔内径在EVE前、后差异均具有统计学意义(P<0.05)。4例支架覆盖区假腔内完全血栓化,20例假腔内部分血栓化;②97支腹部分支及髂总动脉受累,EVE后4支修复,30支不同程度缓解,63支无变化。2支无名动脉受累,EVE后修复;③1例支架伸展不良合并Ⅰ型内漏;④8例支架内漏发生,占26.7%;其中Ⅰ型内漏5例(均位于支架近端),Ⅱ型内漏即肋间动脉漏2例,Ⅰ型与Ⅱ型内漏并发1例。结论:MSCT应作为主动脉夹层EVE后随访并优先选择的主要影像学方法。
Objective：To investigate the follow-up value of multislice spiral CT（MSCT） in patients with aortic dissection（ AD ）after endovascular exclusion（EVE）. Methods：There were 30 AD patients who underwent EVE were examined by MSCT scan pre-and post-operation, the image were compared in order to analyze the true or false lumen, the branch vessel lesions and the changes of in-vessel graft. Result：For all 30 patients,we ground （1） There were significant differences in the size of false lumen and true lumen pre-and postoperation（P 〈0. 05）. In the false lumen,the stents were completely covered by the thrombus in 4 cases, partially covered by the thrombus in 20 cases. （2） There were 97 visceral or iliac arteries involved,after EVE,4 arteries rehabilitated completely,30 arteries alleviated,63 arteries had no changes. There were 2 innominate artery involved ,and they were rehabilitated completely after EVE. （3） Stent graft un-expansion with type I leakage occurred in one patient. （4） The leakage occurred in 8 patients（26. 7% ） ,among them,Rossella＇s leakage type I occurred in 5 cases, （ all near the proximal attachments of the graft） ,type H in 2 cases ,both type I and type II leakage in 1. Conclusion：MSCT was a valuable imaging modality in the follow-up study of AD after EVE in clinical practice.
