Characteristics of atheromatous renovascular disease in Dubai: a single-center experience

To determine the characteristics of atherosclerotic renal artery stenosis (ARAS) in a cohort of patients who attended the Nephrology Department of NMC Specialty Hospital in Dubai from 2006 through 2010, including their clinical and investigational features and their response to various remedial modalities, we studied 20 patients with a diagnosis of ARAS based on magnetic resonance angiography. Three (15%) patients developed acute renal failure (ARF) after the initiation of angiotensin converting enzyme inhibitors or angiotensin II receptor blockers and 13 (65%) patients presented with chronic kidney disease (CKD) of either ischemic nephropathy or nephroangiosclerosis etiology. Four (20%) patients presented with resistant arterial hypertension (RAH). Plasma renin activity was elevated in all the patients. Fifteen (75%) patients were diabetics. We conclude that CKD was the main presentation of ARAS followed by RAH and ARF in our study. Diabetes Mellitus was the main risk factor for ARAS found in our study.
