Possibility of diagnostic and curative endovascular interventions on coronary shunts through radial and ulnar arteries was analyzed in patients with prior coronary bypass grafting. Safety and efficacy of this technique were evaluated in comparison with approach through femoral artery. 90 patients with prior coronary bypass grafting undergoing diagnostic shuntography and stenting of coronary shunts and arteries were enrolled in the study. All patients were divided into two groups: patients from the 1 group underwent interventions through forearm arteries (n=50), patients from the 2 group - through femoral artery (n=40). It is shown that endovascular interventions on shunts and coronary arteries using approach through forearm arteries are safe and effective. Interventions were successful in 98% of cases. Low frequency of complications allows applying this technique in outpatient practice and during short-term hospitalization.
