[Diagnosis of aortocoronary bypass complications]

Thirty-four patients with ischemic heart disease were examined during operation for revascularization of the myocardium. The blood flow in the shunts was measured during the change from extracorporeal to natural circulation. In rise of venous and arterial pressure the blood flow in the shunts increased (positive dynamics) in some patients and decreased (negative dynamics) in others. Positive dynamics were associated with a favourable course of the postoperative period, negative dynamics--with ischemic-type complications. Factors invalidating the myocardium aggravated the initial condition of patients with positive dynamics of the blood flow less than that of patients with negative dynamics. Comparison of dynamic and short-term measurement of the blood flow in the shunts as a diagnostic test for perioperative complications showed the advantage of the dynamic test.
