Late results of embolization of a portal hepatic vein branches in patients, suffering extended hepatic tumors

Abstract

Objective. To analyze late results of preoperative embolization of the portal hepatic vein branches (EPHVB) in patients, suffering extended hepatic tumors and extremely border-like small calculated residual hepatic volume(CRHV). Маterials and methods. From 2004 to 2014 yr the extended hepatic resection (HER) was performed in 285 patients, to whom EPHVB was applied (the main group), аnd in 353 patients as well, but without endovascular preparation (control group). In both groups dynamics of laboratory indices, structure of complications and lethality, late survival were studied. Results. In the main group a trustworthily lower rate of an acute hepatic insufficiency and connected with a lower postoperative lethality - accordingly 2.3 and 4.6%, comparing with a control group - 9.3 and 8.8%, were suggested. The laboratory data dynamics have witnessed a lesser intensiveness of postoperative hepatocytolysis and lesser degree of the hepatic synthetic function lowering in the main group, what have confirmed a better functional adaptation of hepatic residual in patients, to whom preoperative EPHVB was applied. Conclusion. Preoperative EPHVB permits to lower the postoperative complications and lethality rate in patients, suffering hepatic tumors, due to better functional adaptation of hepatic residual.
