six patients with mitral stenosis complicated by renal artery embolism studied prospectively are presented. in five patients there was unilateral and in one patient bilateral renal artery involvement. the diagnosis was confirmed by intravenous pyelography, retrograde pyelography, renal angiography, renal scan or a combination of these. all had atrial fibrillation, proteinuria and elevated ldh l...

To assess the accuracy of renal artery duplex scanning for the purpose of diagnosing atherosclerotic renal artery stenosis, we compared the findings of renal arteriograms to the results of duplex scanning in 41 patients. Using an increase of renal artery peak systolic flow velocity of greater than 180 cm/sec, duplex scanning was able to discriminate normal from diseased renal arteries with a se...

20 Salvatore S. The ability of elementary and secondary school children to sense oncoming car velocity. An appreciable proportion of patients with heart failure or hypertension requiring treatment with an angiotensin converting enzyme inhibitor have widespread atherosclerotic disease. Angiotensin converting enzyme inhibitors have recently been proposed as the treatment of choice in patients wit...

The major issues in approaching patients with renal artery stenosis relate to the role of renal artery stenosis in the management of hypertension, ie, “renovascular hypertension,” and to the potential for vascular compromise of renal function, ie, “ischemic nephropathy.” Ever since the original Goldblatt experiment in 1934, wherein experimental hypertension was produced by renal artery clamping...
