Abstract:

Objectives: Renal artery stenosis (RAS) is among the most common causes of secondary hypertension. Prevalence of RAS are seen in end-stage renal disease (ESRD) patients with hypertension between 1-10%. In our study, we evaluated the data of patients with RAS who were followed up with medical treatment and stenting. Methods: In our study, patients who were thought to have renal artery stenosis (RAS) with renal artery doppler ultrasonography were scanned with contrast-enhanced Magnetic Resonance Angiography (MRA). Fifty-three patients (10 received medical therapy, 43 applied invasive procedure) who diagnosed with RAS evaluated. Results: Follow-up times were 15 (12-84) months in patients who received medical therapy, and 12 (10-96) months in patients who treated with invasive therapy (p = 0.583). Median ages were 56 (19-74) years in medical treatment group, and 60 (15-77) years in invasive therapy group (p = 0.955). Compared with the beginning of treatment, diastolic hypertension was decreased of 12.5% in invasive treatment group opposite medical therapy group (p = 0.040), so eGFR was increased of 5.94% in invasive treatment group. Conclusions: In recent years, several studies about survival in patients with RAS was observed that there was no significant difference between the medical and invasive treatment. Clinical, laboratory, and individual characteristics should be considered in treatment choice.
