DDS was compared to intra-arterial angiography for the diagnosis of significant (> 50%) stenoses of the celiac trunk and the SMA in 38 consecutive patients referred for angiographic evaluation of peripheral arterial occlusive disease. Celiac trunk occlusion was correctly identified by DDS in three of three patients. In patients with significant celiac trunk stenoses, mean peak systolic velocity was 246 (+/- 154) cm/sec and differed significantly (P < 0.05) from the peak systolic velocity (101 +/- 22 cm/sec) of 22 patients with no angiographic evidence of significant stenosis. Five false-negative DDS examinations in patients with > 50% celiac trunk stenoses were noted. Using a peak systolic velocity of > 160 cm/sec (mean value in normal vessels plus 3 standard deviations) to diagnose > 50% celiac trunk stenosis, sensitivity of DDS was 57% and specificity was 100%. However, considering celiac trunk stenoses and occlusions as a single group, the sensitivity rate of DDS in diagnosing significant stenosis and occlusion of celiac trunk was 70%.
在38例因外周动脉闭塞性疾病接受血管造影评估的连续患者中，将双功超声（DDS）与动脉内血管造影术进行比较，以诊断腹腔干和肠系膜上动脉（SMA）的严重（>50%）狭窄。3例腹腔干闭塞患者中，DDS正确识别出3例。在腹腔干严重狭窄的患者中，平均收缩期峰值流速为246（±154）cm/秒，与22例无血管造影显著狭窄证据患者的收缩期峰值流速（101±22 cm/秒）有显著差异（P<0.05）。注意到5例腹腔干狭窄>50%的患者DDS检查结果为假阴性。使用收缩期峰值流速>160 cm/秒（正常血管平均值加3个标准差）诊断腹腔干狭窄>50%时，DDS的敏感性为57%，特异性为100%。然而，将腹腔干狭窄和闭塞视为一组时，DDS诊断腹腔干严重狭窄和闭塞的敏感性为70%。
