Aortoarteritis: a report of 480 cases.

We report 480 patients with aorto-arteritis studied in our group. Among 320 patients, who were diagnosed by aortography the female to male ratio was 2.8:1, and the age of onset ranged from 5-45 years. The patients were followed for 1-27 years (average 6.8 years). Two hundred and eighty-six (59.6%) patients with renovascular hypertension were found in the group. All patients were treated with medical or surgical procedures. One hundred and thirty patients with renovascular hypertension were operated upon by revascularisation or uninephrectomy and 11 patients with renal artery stenosis were subjected to percutaneous transluminal renal angioplasty. There were 55 deaths (11.5%) in the group, cerebral haemorrhage being the major cause of death. Five year and ten year survival rates were 93.1% and 91.1% respectively.
