Regressing Aneurysms in Periarteritis Nodosa

Abstract

Three patients with angiographic evidence of periarteritis nodosa were restudied twelve to thirty-one months after diagnosis. Each demonstrated total disappearance of the aneurysms and an improved vascular appearance. There was no correlation between regression of the aneurysms and the clinical course or therapeutic manipulations. Evidence is increasing that aneurysms and stenoses of small arteries are not limited to patients with classical periarteritis nodosa and may be demonstrated angiographically in several types of necrotizing angiitis.
