摘要
目的:探讨亚急性主动脉夹层腔内隔绝术后瘤体重构的特点。方法:回顾性分析我科1998年9月至2005年10月43例亚急性主动脉夹层腔内隔绝术后随访影像学资料。将主动脉分为S1、S2、S3三段,设定每段主动脉中点所在平面为观察横断面,分别测量每次随访CT各观察横断面真、假腔及瘤体直径,观察其变化情况。结果:术后12个月内S1、S2瘤体及真假腔重构变化较明显,真腔直径逐渐增大、假腔血栓化吸收、瘤体逐渐减小,24个月后变化趋于稳定,而S3段在术后重构变化不显著。结论:亚急性主动脉夹层腔内隔绝术安全有效,术后瘤体重构满意。病人在度过急性期后应尽早行腔内隔绝术,使得瘤体得到较好重构,尽量恢复至发病前状态。
Objective To elucidate the aortic remodeling pattern of subacute aortic dissection after endovascular exclusion. Methods From September 1998 to October 2005, endovascular exclusion for subacute Stanford B thoracic aortic dissection were preformed in 43 patients. The follow-up CT data was respectively analyzed. Aorta was divided into three segments S1,S2 and S3. In cross sections, the diameters of aortic aneurysm, true lumen and false lumen in the middle above the three segments were measured. Results Within 12 months postoperation, S1 and S2 remodeling were evident, and true lumen increased gradually, false lumen thrombosed and absorbed. And after 24 months, the remodeling was stable. However, in segment S3, remodeling was not so evident after operation. Conclusions Endovascular stent-graft exclusion is a safe and effective treatment for subacute Stanford B aortic dissection, and the remodeling of dissected aorta is satisfactory.
