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%.
