PG - 534-8 AB - OBJECTIVES: The purpose of the study was twofold: (1) to identify the incidence of acute mesenteric ischaemia (A.M.Isc.) following cardiopulmonary bypass and (2) to identify factors associated with its development. METHODS: A retrospective review of all autopsy reports from 1st January 1994 to 31st December 2000 was undertaken. Fifty-two patients were identified with acute mesenteric ischaemia at post-mortem following cardiac surgery. Demographic, pre-, intra- and post-operative variables were collected from their case notes. Four age, sex and period matched controls [n=208 (4 x 52)] were randomly selected for each case. Conditional logistic regression was used to compare the cases and controls. RESULTS: A total of 11,202 patients underwent surgery requiring cardiopulmonary bypass (CPB) during the study period with an overall mortality rate of 3%. The autopsy rate was 95% throughout the study period. From autopsy reports 52 patients (corrected for autopsy rate: 0.49% of group) were identified with A.M.Isc. Comparing controls with A.M.Isc. cases by univariate analysis, significant associations (P
