Key result
B-mode aortic ultrasonography closely approximated intraoperative aneurysm measurement, with 75% of measurements within 0.5 cm of true size compared to 38% for physical examination.
Why the study?
Does B-mode aortic ultrasonography provide more accurate measurement of aortic aneurysm size compared to physical examination and lateral roentgenography in patients undergoing elective aneurysmectomy?

Does B-mode aortic ultrasonography provide more accurate measurement of aortic aneurysm size compared to physical examination and lateral roentgenography in patients undergoing elective aneurysmectomy?
Absolute Event Rate: 75% vs 38%
B-mode aortic ultrasonography provides highly accurate preoperative measurements of aortic aneurysm size, closely approximating true intraoperative dimensions.
Norman Hertzer (1978) conducted an observational in Aortic aneurysm (n=53). B-mode aortic ultrasonography vs. Physical examination and lateral abdominal roentgenography was evaluated on Measurement within 0.5 cm of true aortic size. B-mode aortic ultrasonography closely approximated intraoperative aneurysm measurement, with 75% of measurements within 0.5 cm of true size compared to 38% for physical examination.
