To assess influences of intra‐aortic balloon pumping (IABP) on superior mesenteric flow, 15 postoperative patients were examined, in whom distal aspects of balloons were distal to the superior mesenteric artery. Superior mesenteric flow velocity‐time integral in systole (IntS), that in diastole (IntD), and the sum of IntS and IntD (IntS+IntD) were determined on and off IABP (IABP ON‐OFF test). The same parameters were obtained with balloon inflating on every other beat (IABP 1:2 test). The cardiac cycle with balloon inflation during diastole was defined as “1:2 ON,” and the cardiac cycle without balloon inflation during diastole was defined as “1:2 OFF.” (1) IABP ON‐OFF test. IABP increased IntS (p<0.01), IntD (p<0.01), IntS+IntD (p<0.01), and cardiac output (p<0.05). The increments in IntS, IntD and IntS+IntD on IABP are attributed largely to an increase in cardiac output. (2) IABP 1:2 test. IntS during 1:2 OFF was greater than IntS during 1:2 ON (p<0.01), whereas IntD during 1:2 OFF was smaller than IntD during 1:2 ON (p<0.01). There was no significant difference in IntS+IntD between 1:2 ON and 1:2 OFF. These data suggest that juxtamesenteric balloon placement did not interrupt the arterial inflow of a superior mesenteric artery.
