The computed tomography (CT) scans of 71 cases of arteriosclerotic and/or dissecting aortic aneurysms (33 thoracic, 25 abdominal, and 13 thoracoabdominal) were analyzed. Enlargement was seen in all cases, and deformity of aorta was found in 92%. Mural thrombus was evident on CT in 86% of the cases, and its pattern was classified into eight types. The most frequent was the ring type (Type A) followed by the left crescent thrombus (Type H) and the left posterior crescent thrombus (Type D). Calcification was found in 60 cases, and intraluminal calcification was seen in 14 cases.
对71例动脉硬化性和/或夹层主动脉瘤（33例为胸段，25例为腹段，13例为胸腹段）的计算机断层扫描（CT）进行了分析。所有病例均可见主动脉增粗，92%的病例发现主动脉畸形。86%的病例在CT上可见壁内血栓，其形态分为8种类型。最常见的是环形（A型），其次是左新月形血栓（H型）和左后新月形血栓（D型）。60例发现钙化，14例可见腔内钙化。
