The authors have studied the files of 50 consecutive patients (1987-89) operated for abdominal aortic aneurysm (AAA) and examined with CT. The criteria for inclusion were surgical features. CT can be made more accurate for the study of AAA: Thus the location of the neck of the aneurysm relative to the renal arteries was defined in 94% of all cases. In addition, CT yields information about the wall of the aneurysm, whether it be thickened (3 inflammatory aneurysms were properly diagnosed) or, mor importantly, weakened (solution of continuity in the wall in the "prior-to-rupture" appearance). Owing to the quality of its performances and to its noninvasive character, the authors regard CT with contrast injection as an essential technique for the preoperative assessment of abdominal aortic aneurysm in most cases. The examination must be carried out strictly, especially for the contiguous sections of the renal arteries and their extension to the crural arch. As it demonstrates weakened areas more easily, a more accurate study of the aneurysmal wall with CT might increase the surgical indications for some smaller aneurysms, the potential evolution of which does not seem to be associated with their diameter only.
作者研究了1987 - 1989年间连续50例接受腹主动脉瘤（AAA）手术并接受CT检查的患者病历。纳入标准为手术特征。CT在AAA研究中可以更准确：因此，在所有病例中，94%能明确动脉瘤颈部相对于肾动脉的位置。此外，CT可提供有关动脉瘤壁的信息，无论是增厚（3例炎性动脉瘤得到正确诊断），还是更重要的，变薄（在“破裂前”表现中壁的连续性中断）。由于其性能质量和非侵入性特点，作者认为在大多数情况下，注射造影剂的CT是腹主动脉瘤术前评估的重要技术。检查必须严格进行，特别是对于肾动脉的连续节段及其向脚弓的延伸。由于CT更容易显示变薄区域，对动脉瘤壁进行更准确的CT研究可能会增加一些较小动脉瘤的手术指征，其潜在演变似乎不仅仅与直径有关。
