[ASSESSMENT OF LIVER FUNCTION WITH TRANSESOPHAGEAL ECHOCARDIOGRAPHY HEART SURGERY WITH CARDIOPULMONARY BYPASS].

AIM OF THE STUDY: evaluation of arterial and venous liver circulation during cardiopulmonary bypass (CPB) using the method of transesophageal echocardiography (TEE). MATERIALS AND METHODS: 62 patients undergoing reconstructive cardiac surgery with CPB were analyzed. During all the stages of treatment we performed monitoring of mean arterial pressure, heart rate and central venous pressure. TEE was performed using specialized Philips iE-33 3-D matrix multifrequency probe X7-2t in transgastral position. Ultrasonic and dopplerographic measuring of blood flow in hepatic artery and veins was performed before sternotomy, in 30 minutes after starting CPB and after stopping CPB during sternal closure. The speed of bloodflow in hepatic artery, hepatic veins, biochemical blood analysis was evaluated, i.e. lactate level, AST ALT ratio before the intervention, during CPD and in early postoperative period RESULTS: Correlation between blood flow in liver vessels and dynamics of biochemical analysis. It is considered to that this change during procedures with CPB may be linked with liver insufficiency during first hours of evaluation. In other words reduced blood flow in liver vessels may be one of the liver insufficiency early symptoms and is one of factors that require correction during operative and early postoperative period. So dynamic follow-up of hepatic circulation may be used as a method of early diagnostics of functional organ disorders.
