Abstract

Atherosclerotic renal artery stenosis (RAS) is an underdiagnosed disorder and a treatable etiology of hypertension and renal insufficiency. All patients were referred for a transesophageal echocardiogram for various indications. Abdominal ultrasound was performed in 69 patients, 43 with severe thoracic aortic plaque (≥4 mm) and 26 controls with no or mild plaque (≤2 mm). Severe RAS (≥60%) was defined as flow velocity ≥1.8 m/s and a renal:aortic ratio of ≥3.5. There were 8 cases of RAS (all severe) in the 43 patients with severe aortic plaque (19% vs 0% of controls; p = 0.02). Severe plaque (p = 0.02) and hypertension (p = 0.03) were correlated with RAS. On multivariate analysis, severe plaque (p = 0.017) and hypertension (p = 0.002) remained independently correlated with RAS. In a paired analysis, matched for age and gender (McNemar), severe plaque was significantly associated with RAS (p = 0.008). Severe thoracic aortic plaque is strongly associated with RAS, which is found in 19% of patients with severe plaque. Patients found to have severe aortic plaque on transesophageal echocardiography should be screened for RAS.
