In a review of 17 cases in which the CT diagnosis of abdominal aortic aneurysm rupture was prospectively made and for which surgical correlation was available the CT diagnosis was correct in 10 and incorrect in seven. Two of the false positives were retrospectively reinterpreted as negative for rupture. Characteristics of 10 surgically confirmed cases revealed a spectrum of appearances not always in agreement with prior published reports, probably due to the age and magnitude of the aortic leaks at the time of diagnosis. The most common characteristic of aneurysm leak (eight of 10 cases) was an abnormal soft tissue collection located adjacent to the posterior aspect of the aneurysm, a sign not previously emphasized in other reports. Renal displacement was also a valuable sign but was present in only three cases, all of which had large hemorrhages. Other characteristics of aortic rupture such as density of the collection and sharpness of its margins were not found to be generally useful.
在一项对17例病例的回顾性研究中，这些病例均前瞻性地进行了腹主动脉瘤破裂的CT诊断且有手术相关性资料，其中CT诊断正确的有10例，错误的有7例。两名假阳性病例经回顾性重新解读后被判定为破裂阴性。10例经手术证实的病例的特征显示出一系列表现，并不总是与先前发表的报告一致，这可能是由于诊断时主动脉漏血的年龄和程度所致。动脉瘤漏血最常见的特征（10例中的8例）是在动脉瘤后方毗邻处有异常软组织聚集，这一征象在其他报告中未曾被着重强调。肾脏移位也是一个有价值的征象，但仅在3例病例中出现，且这3例均有大量出血。主动脉破裂的其他特征，如聚集物的密度及其边缘的清晰度，一般认为并无用处。
