SURGICAL ASPECTS OF CORONARY AND RENAL PATHOLOGY IN MYOCARDIAL REVASCULARIZATION ON THE BEATING HEART
Abstract
Assess impact of renal artery stenosis (RAS) angioplasty on renal function, need and timing of this procedure during coronary artery bypass grafting (CABG). Changes of renal function parameters (urea, urea nitrogen and creatinine) were analyzed in 81 patients with RAS in combination with ischemic heart disease. Depending on the timing of RAS stenting in relation to the CABG operation patients were divided into 4 groups. Analysis of the data showed that regardless of time or performed RAS stenting or without it the investigated parameters of renal function hardly changed, decrease of blood pressure in all groups was apparent. Retrospective analysis of data showed that the elimination of RAS had no positive effect on renal function, however, helped to reduce blood pressure. Routine use of renal artery stenting for renal function improvement before CABG surgery has no advantages.
