Forty-eight patients undergoing elective repair of an abdominal aortic aneurysm were randomly selected for correlation of diagnosis of aneurysm and aneurysm size as determined by direct surgical measurements, ultrasound examination, and lumbar spine X-ray. The preoperative diagnosis was confirmed by lumbar spine plain films in 72% of patients and by B-mode ultrasound in all of patients. Aneurysm size could be measured by lumbar spine X-ray in 55% of patients and with gray-scale B-mode ultrasound in all of patients. The average difference between surgically measured and roentogenographically determined aneurysm size was 1.5 cm in the transverse diameter and 0.87 cm in the anteroposterior diameter of the aneurysm. The average difference between surgically measured aneurysm size and ultrasound-determined external wall diameter of the aneurysm was 0.42 cm in the transverse diameter and 0.29 cm in the anteroposterior diameter. From these data we conclude that gray-scale B-mode ultrasound of the aorta is a more sensitive and accurate method of assessing abdominal aortic aneurysms than is the use of lumbar spine X-ray.
48例接受腹主动脉瘤择期修复术的患者被随机选取，以对比通过直接手术测量、超声检查和腰椎X线检查所确定的动脉瘤诊断结果与动脉瘤大小。术前诊断在72%的患者中通过腰椎平片得以证实，在所有患者中均通过B型超声得以证实。55%的患者可通过腰椎X线测量动脉瘤大小，所有患者均可通过灰阶B型超声测量动脉瘤大小。手术测量的动脉瘤大小与X线检查确定的动脉瘤大小之间，在动脉瘤横径上的平均差异为1.5厘米，前后径上的平均差异为0.87厘米。手术测量的动脉瘤大小与超声确定的动脉瘤外壁直径之间，在横径上的平均差异为0.42厘米，前后径上的平均差异为0.29厘米。从这些数据我们得出结论，与使用腰椎X线相比，主动脉灰阶B型超声是评估腹主动脉瘤更敏感、更准确的方法。
