title: [Clinical and angiographic characteristics of renovascular hypertension].
abstract: Clinical and angiographic characteristics of renovascular hypertension were studied in 95 patients. The patients were divided into 3 groups: 55 cases with aortic arteritis (group AA), 27 with fibromuscular dysplasia (group FMD) and 9 with atherosclerosis (group AS). The patients in group AS were significantly older in age and had longer history of hypertension. Abdominal bruit was heard significantly more often in group AA and serum potassium was significantly lower in group FMD. Angiographic data showed that in group AA lesions in thoracic aorta and abdominal aorta was found in 81.4% and those involving both renal arteries in 52.5%. In group FMD, 82.5% of patients had lesion in renal artery on one side and none had lesion in thoracic and abdominal aorta. In group AS, lesions were found mainly in thoracic and abdominal aorta, accounting for 77.7% and lesions in renal arteries were mainly unilateral. In group AA, lesions were found in 90 renal arteries altogether. Among them, 58.9% was in the proximal part of the renal artery; the lesion was either localized stenosis (67.8%) or obstruction (17.7%). In group FMD, lesions were found in 33 renal arteries altogether. Among them, 48.5% was in the middle or distal part of the renal artery and 27.3% resembled string of beads. In group AS, a total of 10 renal arteries were involved with 4 (40%) of ostial stenosis and 4 (40%) total obstruction.
