Factors affecting the effectiveness of endovascular kidney revascularization in patients with renal arteria stenosis

Abstract

The paper analyzes the results of surgical treatment of 109 patients with renal artery stenosis and manifestations of ischemic kidney disease (IBD) in the form of renovascular arterial hypertension. Blood pressure normalization was noted in 97 (89%) patients in the early and in 91 (84%) in the late postoperative periods. A sequential regression and multivariate correlation analysis of the factors of a good outcome of the operation was carried out. It was determined that significant prognostic factors are the presence of microalbuminuria and the duration of the history of arterial hypertension before surgery (correlation coefficients (HR) –0.684 and –0.695 at p = 0.0001). With these factors, the difference between the assessment of cumulative survival without clinical deterioration and the Cox proportional hazards regression model was statistically significant.
