目的：评价主动脉壁内血肿(IMH)的溃疡样改变(ULP)、穿通溃疡(PAU)的 DSCT 影像表现特点。方法回顾性分析本院112例 IMH 患者的 DSCT 图像,观察血肿形态,比较 IMH 不伴或伴 ULP 及 PAU 组间最大主动脉直径、最大血肿厚度、溃疡深度的差别,以及 ULP 及 PAU 在不同 Stanford 类型的 IMH 及主动脉各段的分布情况。结果112例 IMH 在 DSCT 图像上均表现为平扫呈主动脉壁环形或新月形高密度影及增强扫描无强化的特征。68例(68/112,61%)IMH 伴有 ULP 及 PAU,其中 ULP 21例(21/112,19%),PAU 47例(47/112,42%),平均最大深度 ULP 为(0.48±0.15)cm,PAU 为(1.08±0.56)cm。A 型29例, ULP 4例(4/29,14%),PAU 9例(9/29,31%)；B 型83例,ULP 17例(17/83,20%),PAU 38例(38/83,46%)。21例 ULP 单发14例(14/21,67%),多发7例(7/21,33%)；47例 PAU 中,单发27例(27/47,57%),多发20例(20/47,43%)；PAU 和 ULP 同时共存19例；PAU 较 ULP 更容易发生在降主动脉及远端主动脉(P =0.028)。结论IMH 患者容易伴发 ULP 或 PAU,DSCT 可客观评价 IMH 及其 ULP 及 PAU 的 CT 表现特征。

Objective To evaluate the imaging features of ulcer-like projections (ULP)and penetrating atherosclerotic ulcers (PAU)of intramural hematoma(IMH)using dual-source CT (DSCT).Methods Retrospectively analysis of DSCT imaging data of 1 12 patients in our hospital was performed.The shape of hematoma and location of ULP and PAU were evaluated Stanford A and B IMH depicting on DSCT images.The maximum diameter of aorta,maximum thickness of hematoma,deepness of ulcer were com-pared between in patients of IMH with or without ULP and PAU.Results IMH manifested as circular or crescent high density on plain scan and without contrast enhancement on DSCT images in 1 12 cases.Among of them,68 cases(68/1 12,61%)of IMH had ULP or PAU,in which there were 21 cases(21/1 12,1 9%)with ULP and 47 cases(47/1 12,42%)with PAU,the mean maximum depth was (0.48±0.1 5)cm in ULP and (1.08±0.56)cm in PAU.There were 4 cases with ULP and 9 cases with PAU in 29 cases of Stanford type A,while 1 7 cases with ULP and 38 cases with PAU in 83 cases of Stanford type B.There were 14 cases with single ULP and 7 cases with multiple ULP in 21 patients with ULP,while there were 27 cases with single PAU and 20 cases with multiple PAU in 47 patients with PAU.There were 1 9 cases with both PAU and ULP.There was statistical significance that PAU occurred more likely in the descending aorta and distal aorta than that in ULP (P =0.028).Conclusion IMH patients are susceptible to ULP and PAU,DSCT can objectively evaluate CT features of ULP and PAU of IMH.
