About this trial
Hypertension is a major risk factor for a variety of cardiovascular diseases. When hypertension results from increased vascular resistance due to a narrowing of the descending aorta, it can be effectively treated with stenting. More recently, evidence suggest that stenting in more distal parts of the arterial vascular bed is also associated with a reduction in blood pressure. The investigators hypothesize that stenting of occlusions more distal of the descending aorta decreases the central blood pressure and afterload as reflected by NT-proBNP (N-terminal pro-Brain Natriuretic Peptide), a biomarker of intracardiac pressures and predictor of heart failure events. The goal of this pilot study is to prospectively investigate changes in blood pressure after stent placement in the aorto-iliac region.

Trial outcomes
Primary outcomes
The primary objective is to describe the changes in arterial blood pressures between baseline and 12 months follow-up after endovascular treatment of an occlusion of the infrarenal aorta and/or common iliac arteries.
Secondary outcomes
To gather information about the association between cardiac biomarkers (hemoglobin, creatinin, NT-pro-BNP) on blood pressure at 12 months in patients with treatment for an occlusion of the infrarenal aorta and/or common iliac arteries.
To determine if treatment of an occlusion of the infrarenal aorta and/or common iliac arteries will change the Pulse Wave Analysis (PWA) Pulse Wave Velocity (PWV) measurements at 12 months, compared to baseline.
To investigate if treatment of an occlusion of the infrarenal aorta and/or common iliac arteries will decrease or increase the number of anti-hypertensive medication use at 12 months, compared to baseline.
