A total of 39 cases are analized, of post-operative intestinal infarction, that occured exclusively in patients with cardiovascular diseases. The clinical signs appeared early in most of the cases (85,4% in the first 72 hours; 48,4% in the first 24 hours) and the manifestations were typical in 42,4% and non-significant in 35% of the cases. Since none of the cases benefited from a successful therapy the authors suggest that stress should be laid on prophylactic measures (correct re-equillibration).
