Abstract
During the last 10 years, 7 hypertensive patients due to segmental renal ischemia or infarction among total 48 cases of renovascular hypertension have been observed in our clinic.
These 7 cases of renal arterial branch stenosis consist of 5 men and 2 women. The youngest case was aged 12 and the oldest 31. Their blood pressures were ranged from 160-225mmHg in systolic and from 84 to 150 in diastolic. Abnormal intravenous pyelogram was found in 4 out of 7 cases. So far as our experience was concerned, clinical features, urinalysis, radioisotope renography, renoscintigraphy and split renal function study were of little value for screening of the patients with renal arterial branch stenosis. However, angiography and provocation test of renin secretion are the best tools for making diagnosis of this type of hypertension. Surgical treatment including nephrectomy and revascularization relieved the hypertension in 5 patients. Antihypertensive drugs were given in one of 5 operated cases and in 2 non-operated cases. Six out of 7 patients remained normotensive.
