BILATERAL RENAL ARTERY STENOSIS IN THREE HUNDRED CANDIDATE PATIENTS FOR CORONARY ARTERY ANGIOGRAPHY

Introduction. Renovascular disease is the commonset form of surgically curable hypertension Estimates of the prevalence in general population range from 0.2 percent to 4 percent. It is the most common secondary form of hypertension that is not easily recognizable but curable. We studied the frequency of bilateral renal artery stenosis in patients who had been candidated for coronary artery angiography. Methods. Angiography of oronary and renal artery were done in three hundred patients (56.5 percent female and 43.5 percent male), simultaneously. The procedure was done by digital substraction angiography tract in chamran hospital (affiliated ti IUMSHS). Results. Fifthy patients had renal artery stenosis. Fourthy six patients had unilateral and four patients had bilateral renal artery stenosis. Only 8 percent of renal stenosis was bilateral. Discussion. Atherosclerosis is the most frequent cause of renal artery stenosis. It is often bilateral and progressive, but in this study only 8 percent of patients (1.3 percent of all patients that undergo angiography) had bilateral renal artery stenosis. Therefore in our study bilateral renal artery stenosis was much lower from previous study in other country.
