A comparison was made between angiography (AI), computer tomography (CT) and ultrasound (US) in the preoperative evaluation of 85 consecutive patients with abdominal aortic aneurysm. A total of 63 AI, 24 CT and 43 US were performed. It is concluded that the diagnostic accuracy in identifying aneurysms is higher for CT and US than for AI. AI and CT provide more correct data concerning the anatomy in the region of the renal arteries than US. We suggest that a non-invasive technique should be used for preoperative verification of the diagnosis. AI should only be used when the upper limit of the aneurysm and the relation to the renal arteries cannot be defined by non-invasive methods and, furthermore, in all cases with clinical signs of stenotic disease of the iliac arteries.
对连续85例腹主动脉瘤患者进行术前评估时，对血管造影（AI）、计算机断层扫描（CT）和超声（US）进行了比较。共进行了63次AI、24次CT和43次US检查。得出的结论是，CT和US在识别动脉瘤方面的诊断准确性高于AI。与US相比，AI和CT能提供有关肾动脉区域解剖结构的更准确数据。我们建议应使用非侵入性技术进行术前诊断验证。仅当非侵入性方法无法确定动脉瘤的上限及其与肾动脉的关系时，以及在所有有髂动脉狭窄疾病临床体征的病例中，才应使用AI。
