[Central hemodynamics in the remote period in children operated for extrahepatic portal hypertension].
The authors studied functional state of circulation in various terms after operation. Depending on anastomosis creation two group of patients different by visceral hemodynamics change were identified. 58 patients were examined before operation, one year and later after the operation. Functional state of central hemodynamics was evaluated with echo- and Dopplercardiography. It was revealed that after operation the number of children with hyperdynamic type of circulation decreased. A year after distal splenorenal anastomosis creation number of children with hyperdynamic type of central hemodynamics decreased by 20%. Later, regardless of anastomosis type increased cardiac index was revealed in 32.32 and 36.3% children respectively after total and selective anastomosis creation. After total bypass more severe hemodynamic disorders (diastolic dysfunction and inotropic disorders) developed. After distal splenorenal anastomosis creation hemodynamic disorders were seen later due to increase of bypass volume blood flow. Increase of venous return leads to moderate diastolic overloading and myocardial hypertrophy.
