[Computerized tomography in evaluating the function of aortocoronary shunts].
An examination was made of 38 patients undergone aortocoronary bypass surgery. Comparing the density of content in the aorta and shunt before and after bolus contrast in computerized tomography makes it possible to evaluate the patency of the aortocoronary shunt. A shunt patency coefficient (SPC) was proposed, which fitted the ratio of density differences in the shunt to those in the lumen of the ascending aorta before and after the injection of a contrast agent. SPC equal to 0.5 or more is indicative of a good patency of the aortocoronary shunt, but that being 0.3 or less suggests no or extremely poor function of the shunt. SPCs that are equal to 0.3-0.5 are transient indicators of its patency.
