Introduction: Renovascular hypertension is the second most frequent cause of secondary arterial hypertension, after parenchymal damage (or chronic kidney disease) which stands first. Nowadays, there is a lack of evidence to support therapeutic interventions that impact arterial pressure control in a positive way, or that help avoiding renal disease. Methods: Observational retrospective studiy performed on patients undergoing angioplasty / stent management for angiographically significant renal stenosis. The effect of the intervention was indirectly evaluated by means of the change in the number of pills taken every day before and after the procedure. Results: A total of 34 patients were included in this research, as it was observed that the median of the take of prior antihypertensive medicines to the procedure was 5,5 pills (IQR 3 - 18) and after the procedure was 5 pills (IQR 2.75 – 7.25), Z = -1.042 for p-value = 0,16. Conclusion: No difference was found in the control of arterial pressure, measured by the reduction in the number of antihypertensives pills that patients take on a daily basis.
