Abstract:
In 17-30% of subjects, at least one kidney is supplied by more than one artery arising from the aorta. Subjects with multiple renal arteries have been reported to suffer more frequently from hypertension, But the precise association between hypertension and multiple renal arteries was not yet defined. A 20- year old woman presented clinical manifestations of renovascular hypertension. Basal renin activity was elevated, and time-activity curves showed delayed peak time at captopril renal scan. Angiography showed multiple renal arteries with 2 right and left 3 arteries. There was neither stenosis nor inflammation. We strated angiotensin-receptor blocker, calcium channel blocker, and beta-blocker. The patient currently remains normotensive in an outpatient unit. In general, accessory renal arteries are narrower and longer than main artery. As a results, the renal segments supplied by accessory vessels might have lower levels of blood pressure than the remainder of the parenchyma, thereby increasing the renin secretion. So hypertension associated with multiple renal arteries might be involved in renin-angiotensin-aldosterone system activation.
