A retrospective study was undertaken to evaluate the appearance of the aortic wall on computed tomography for the purpose of developing criteria for differentiating acute aortic intramural hematoma from thrombosed false lumen seen in aortic dissection. Computed tomography angiography findings of the thoracoabdominal aorta in 23 patients with suspected intramural hematoma and 25 with thrombosed false lumen were reviewed. The more common features of an intramural hematoma were hyperattenuation of the aortic wall, wall thickness less than a quarter of the aortic diameter, intrinsic wall calcification, a lesion extending around the entire aortic circumference, and ulcer-like projections that may be precursors of intramural hematoma. Wall thickness less than a quarter of the aortic diameter, lesion extending around the entire aortic circumference, and ulcer-like projections were the most useful indicators for distinguishing intramural hematoma from the thrombosed false lumen in aortic dissection.
进行了一项回顾性研究，以评估计算机断层扫描上主动脉壁的表现，目的是制定区分急性主动脉壁内血肿与主动脉夹层中血栓形成的假腔的标准。回顾了23例疑似壁内血肿患者和25例血栓形成假腔患者的胸腹主动脉计算机断层扫描血管造影结果。壁内血肿更常见的特征是主动脉壁高密度、壁厚度小于主动脉直径的四分之一、壁内钙化、病变环绕主动脉整个圆周延伸，以及可能是壁内血肿先兆的溃疡样突出。壁厚度小于主动脉直径的四分之一、病变环绕主动脉整个圆周延伸以及溃疡样突出是区分壁内血肿与主动脉夹层中血栓形成假腔的最有用指标。
