STATE OF HEPATIC HEMODYNAMICS IN TRANSPLANTATION OF ITS RIGHT PART WITH MEDIAN HEPATIC VEIN

Peculiarities of regional hemodynamics in transplantation of right hepatic part with median hepatic vein were studied. The blood flow parameters — the volume portal blood flow (VPBF), linear speed of blood flow (LSBF), the resistance index (RI) in hepatic artery; phasic structure of the blood flow along hepatic veins were determined in 31 patients in accordance to ultrasonographic flowmetry data. Maximal value of VPBF was observed on a second postoperative day, minimal one —on the fourth day. Аrterial blood flow have had enhanced immediately after transplantation up to maximal one on the second day, and from second to the fourth day — have had reduced to minimal one. Phasic structure of blood flow along hepatic vein have had changed postoperatively in 12 (38%) patients. Changes in the hepatosplanchnic blood flow after transplantation constitutes a consequence of the vascular resistance reduction, the venous outflow and regenerative activity of the transplanted hepatic part improvement.
