[Impact of plasmapheresis on intraorgan blood flow of the transplanted kidney in the early postoperative period].

[Article in Russian]

Abstract

Kidney transplant is inevitably subjected to ischemic and reperfusion injury. In many cases, this is due to a violation of intraorgan hemodynamics. Severity of such damage can be reduced using different methods of extracorporeal hemocorrection. The aim of the study was to examine the intraorgan blood flow of kidney transplant and assess the impact of plasmapheresis on its primary function in the early postoperative period. Plasmapheresis with replacement from 1,25 to 3,5 liters of plasma was applied in 40 recipients of the Group 1; in 40 recipients of Group 2 plasmapheresis was not performed. High resistance index (Ri > 0,9) at low flow velocities in the interlobular arteries at the first day after surgery is an informative criterion for the diagnosis of acute tubular necrosis and indicates the inadequate blood supply of kidney. Plasmapheresis has promoted the normalization of renal hemodynamics. Immediate graft function in patients of Group 1 was observed in 36 patients, whereas only in 19 patients of Group 2. In the Group 1, there were no patients with primary non-functioning graft, while there were three such patients in Group 2. Thus, plasmapheresis in the early postoperative period, no later than 3-5 h after reperfusion of the graft, has a positive effect on the functional status of the transplanted kidney.
