[Renal arteries stenting. Indications, procedure, results].
Vasorenal hypertension occurs approximately in 5% of patients, suffering arterial hypertension and in majority of them constitutes the consequence of the renal arteries stenosing atherosclerosis. Stenting constitutes the method of choice in the treatment of the renal artery stenosis. Endoprosthesis of renal artery was performed in 113 patients, in 10 of them--bilateral stenting. Angiographic effect was achieved in more than 98% of observations and the clinical one--in more than 85%. Severe intraoperative complications were absent, all the patients are alive. In 13 patients the restenosis in the stent had occurred in 6-18 months after the operation, presenting by the clinical signs recurrence. To these patients the balloon angioplasty in the stent was accomplished. The depiction of technical peculiarities of the diagnosis and the procedure of the renal arteries stenting was suggested. According to modern recommendations of ACC/AHA, the stenting is indicated in the patients, suffering renal artery stenosis, and cardiac weaknesparoxysms, progressing arterial hypertension, unstable stenocardia, bilateral arterial affection. In the absence of symptoms, the efficacy of revascularization is not proved.
