RESUMO
The study included a total of 109 patients presenting with combined atherosclerotic lesions of coronary and renal arteries. Depending on severity of angina pectoris, the patients were subdivided into two groups. Group One consisted of patients subjected to revascularization of the myocardium and kidneys, and Group Two comprised those with a dominating clinical picture of vasorenal hypertension syndrome and undergoing surgery on renal arteries alone. Combined revascularizations were carried out in 31 patients. Of these, five underwent single-stage endovascular interventions on coronary and renal arteries. Isolated interventions were performed in 78 patients. Selectivity of revascularisations of vascular basins was determined first of all by the degree of coronary impairments, arterial hypertension, and the presence of chronic renal failure. No cases of hospital lethality were registered. The 10-year survival rate after renal revascularization amounted to 80.1%, after combined operations to 90.9%. In the immediate postoperative period improvement following isolated renal revascularization was achieved in 62 (86.1%) patients, after isolated coronary artery bypass grafting and combined operation - in all patients. The long-term outcomes turned out to be better after combined operations (80.0%) as compared to those after isolated operations on renal arteries (70.3%).
