Role of Endovascular Recanalization and Stenting of Total Occlusions of The Renal Arteries For Blood Pressure Control in Resistant to Treatment Hypertension-Juniper Publishers
JUNIPER PUBLISHERS-OPEN ACCESS JOURNAL OF CARDIOLOGY & CARDIOVASCULAR THERAPY Abstract Purpose: To assess t! he effect on blood pressure (BP) control and rennin levels of the percutaneous recanalization of totally occluded renal arteries in patients with resistant arterial hypertension, preserved blood flow in the sub-segmental renal arteries, and high level of plasma rennin. Methods: Between 2011 and 2015, we examined 7 patients with total occlusion of a Percutaneous recanalization was attempted in all of them. Success was achieved in 6 (85.7%) of the cases. All patients were hypertensive before the procedure, with mean BP values of 167.1/95.1 mmHg under systematic antihypertensive treatment with at least 3 antihypertensive agents. In all patients, plasma rennin activity levels were more than 2,5 ng/mL/h before the procedure. The patients had duplex signs of occluded renal artery and partially preserved subsegmental flow. Two of the patients showed normal s
