[In-hospital results of renal artery stenting in patients with multifocal atherosclerosis].

OBJECTIVE

A retrospective analysis of in-hospital results of renal artery stenting in patients with multifocal atherosclerosis.

MATERIAL AND

METHODS

The study included 19 patients who underwent stenting for renal artery stenosis for the period 2011-2015 in the Kemerovo Cardiology Dispensary. Renal function was assessed considering glomerular filtration rate (GFR). Blood pressure and GFR were evaluated before the stenting procedure and at discharge.

RESULTS

Stenting resulted optimal outcomes in all 19 patients. Severity of residual stenosis was 11±3%. In-hospital mortality was absent. Blood pressure in early postoperative period was similar to baseline values. One patient had a normalization of blood pressure up to 115-140/85-90 mm Hg without administration of antihypertensive drugs. Decrease of systolic blood pressure up to 155.3±32.6 mm Hg was noted in other patients at discharge. Blood creatinine levels decreased up to 0.167±0.56 mmol/L. In addition, mean GFR increased from 34.17 ml/min/1.69 m2 up to 37.16 ml/min/1.69 m2.

CONCLUSION

Endovascular treatment of renal artery stenosis and secondary hypertension is effective and relatively safe approach.
