Hypertension depends upon various factors such as resistance, pressure difference viscocity, caliber and length of a vessel according to Hagen–Poiseuille law. Length of a vessel is one of the important causes of hypertension of reno–vascular origin in adolescence in the aberrant renal arteries. An adolescent girl with bilateral uveitis and hypertension was evaluated for the cause of hypertension. Serum rennin and aldosterone levels favoured hypertension of renovascular origin. Ultrasonography and C.T. scan angiography of the abdomen revealed multiple aberrant renal arteries without any stenosis. In the absence of renal artery stenosis length and caliber of the aberrant arteries are the parameters which contribute significantly to renovascular hypertension.
