Percutaneous angioplasty and stenting in treatment of chronic occlusions of renal arteries

The article presents results of examination and treatment of 14 patients aged from 46 through 79 years with chronic occlusion of one of the renal arteries in each of them and subocclusion of the contralateral renal artery in 13 patients due to atherosclerosis. At first percutaneous intraluminal angioplasty and stenting were performed in 13 out of 14 patients with stenosis of the renal artery. Then at once only percutaneous intraluminal angioplasty of the occlused renal artery was performed in 10 out of 14 patients and within 36 hours on average the implantation of stents in case of patency of the renal artery proper and its branches, according to the findings of control angiography, in these arteries with the optimal result. The percutaneous intraluminal angioplasty and stenting are relatively safe and effective methods of reestablishment of patency of the renal arteries after their chronic occlusion.
