Role of Endovascular Recanalization and Stenting of Total Occlusions of the Renal Arteries for Blood Pressure Control in Resistant Hypertension-Juniper Publishers
JUNIPER PUBLISHERS-OPEN ACCESS JOURNAL OF CARDIOLOGY & CARDIOVASCULAR THERAPY Abstract The purpose of our research was to assess the 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. we examined 7 patients with total occlusion of a renal artery and collected data for partially preserved sub segmental circulation. 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 par...
