To evaluate the reliability of helical computed tomography (CT) as sole preoperative diagnostic technique for abdominal aortic aneurysms (AAA) and to compare these results with the surgical findings.
Thirty-three patients undergoing elective surgical repair.
Helical CT, Doppler exam of lower limbs, digital angiography, in case of peripheral vascular disease, and intraoperative evaluation.
Helical CT correctly detected, in all cases, the proximal and distal extent of the AAA. The coeliac axis and its branches, the superior mesenteric artery and renal vessels as well as the inferior vena cava were always clearly depicted, showing anatomical variants or pathological involvement in 14 patients (42.4%).
Helical CT can be used as the sole method for preoperative imaging of AAA. It allows a complete and precise evaluation of size, extent and relationship of the AAA, the surrounding vessels and other abdominal structures.
评估螺旋计算机断层扫描（CT）作为腹主动脉瘤（AAA）术前唯一诊断技术的可靠性，并将这些结果与手术结果进行比较。
33例接受择期手术修复的患者。
螺旋CT、下肢多普勒检查、数字血管造影（用于周围血管疾病患者）以及术中评估。
在所有病例中，螺旋CT均正确检测出AAA的近端和远端范围。腹腔干及其分支、肠系膜上动脉、肾血管以及下腔静脉始终清晰显示，14例患者（42.4%）存在解剖变异或病理累及。
螺旋CT可作为AAA术前成像的唯一方法。它能够对AAA的大小、范围以及与周围血管和其他腹部结构的关系进行全面、精确的评估。
