RESUMO
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. Ðrterial 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.

The results of treatment of 55 patients, in whom hepatic resection was performed in 2004-2011 yrs, were analyzed. In 30 patients (main group) various kinds of hepatic resection was done for chronic abscess of the organ; in 25 (control group)--hepatic resection was conducted for hepatic tumors. In both groups o patients a comparative estimation of hepatic functional state after the organ resection was conducted in accordance to albumin level in the blood serum, the coagulogram indices, integral ration of transferases activity and a bilirubin content. There was proved, that a hepatic functional state disorders after its partial resection in patients, suffering chronic hepatic abscess, are similar to those in tumoral hepatic affection.

The results of histological investigation, conducted in 27 patients, operated on for chronic hepatic abscess, are presented. Macroscopic and microscopic characteristic of all zones of hepatic affection is adduced, the mechanisms of formation of pyogenic membrane, zones of infiltration and fibrosis in chronic hepatic abscess formation are delineated.
