The Relationship Between Hypertension and the Multiplicity of Renal Arteries in Young Men with Hypertension

Abstract

The aim of this study is to determine the relationship between hypertension and the presence of multiple renal arteries in young male patients. Renal arteriographic data of seventy-two young hypertensive men (age: 26.1 ± 6.2 yrs, blood pressure [mmHg]: 162 ± 17.5/104.6 ± 10.1) were examined retrospectively. Angiography was performed in order to exclude the diagnosis of renal artery stenosis. The renal arteriographic data were as follows: no renal arterial abnormalities in 39 patients (54.2%), multiple renal arteries in 24 patients (33.3%), renal artery stenosis in 3 patients (4.2%), unilateral hypoplastic kidneys in 3 (4.2%), horse-shoe kidneys in 2 (2.8%) and arterio-venous malformation in 1 (1.3 %). In patients with multiple renal arteries there were positive correlations between body mass indices and blood pressures (r = 0.58, p < 0.05 for systolic, and r = 0.63, p < 0.001 for diastolic). Despite the high prevalence of multiple renal arteries in young hypertensive men, it’s difficult to declare this abnormality had an obvious role in the pathogenesis of hypertension.
