PITFALLS IN THE DIAGNOSIS OF ORIGIN STENOSIS OF THE CELIAC AND SUPERIOR MESENTERIC-ARTERIES WITH TRANSABDOMINAL COLOR DUPLEX EXAMINATION

The purpose of this study is to evaluate the effects of respiration, l ocalization of the Doppler sample, and the presence of origin stenosis on the Doppler parameters of coeliac and superior mesenteric arteries in 22 patients undergoing elective abdominal vascular reconstructive surgery under standardized stable anesthesia, Deep inspiration decreas ed peak systolic and end diastolic velocities of the coeliac artery or igin, Proximal to distal Doppler velocities of normal coeliac and supe rior mesenteric artery origins were comparable, However, in the presen ce of an origin stenosis, the increase of Doppler velocities at the or igin of the coeliac and superior mesenteric arteries is likely to be m issed by transabdominal scanning.
