A study was made of the accuracy of different methods currently used in assessing the transverse diameter of abdominal aortic aneurysms. The maximum transverse diameter of the abdominal aorta was estimated by clinical palpation, plain radiology, ultrasonography and aortography, in a group of 47 patients who were subjected to either a surgical exploration or elective aneurysm resection. The results of these estimations were compared with the actual measurements obtained during the surgical procedure. Measurements of aortic wall calcification seen on the plain X-ray film correlated best with the operative findings. However, calcification was seen in only 30% of the patients. Ultrasonography was almost universally applicable as a technique of assessing aortic size and was found to be a reliable technique for measuring the aortic diameter.
对目前用于评估腹主动脉瘤横径的不同方法的准确性进行了一项研究。在一组47例接受手术探查或择期动脉瘤切除术的患者中，通过临床触诊、普通放射学、超声检查和主动脉造影术对腹主动脉的最大横径进行了估计。将这些估计结果与手术过程中获得的实际测量值进行了比较。普通X线片上所见的主动脉壁钙化测量值与手术结果相关性最好。然而，仅30%的患者可见钙化。超声检查作为一种评估主动脉大小的技术几乎普遍适用，并且被发现是一种测量主动脉直径的可靠技术。
