title: [Indications for angiographic study of renal arteries in elderly hypertensive subjects].
abstract: During a 30 months period, 70 patients (60-84 years old) underwent a renal artery angiographic investigation, either by combined intravenous angiography and pyelography, either by intravenous or intra-arterial digital angiography. Thirty-nine were males, 31 were females. All patients were hypertensive. Thirty-three had a normal renal function and 37 had a renal insufficiency arbitrarily definite as creatinine clearance lower than 60 ml/min (m = 33 +/- 15 ml/min). Eight aortic anevrysms were discovered. Thirteen patients (18.6%) had atherosclerotic renovascular disease. Criteria which led to undertake these investigations and results are listed in the following table. [table; see text] Transluminal percutaneous angioplasty and surgical treatment were performed 7 and 3 times respectively. In one case, nephrectomy was done. In all these patients but one, improvement of hypertension and/or renal function occurred. In patients with renal impairment, difference in size between the two kidneys detected by echography or plain abdominal X-rays were noted in 8 among the 9 patients with renovascular disease; six among them had proteinuria less than 0.5 g/day. In conclusion, in hypertensive patients older than 60, criteria for detection of renovascular disease are the same as in younger patients. When renal function is decreased, difference in size between the two kidneys requires an angiographic evaluation. Proteinuria does not exclude renovascular pathology.
