Angiographic Documentation of De Novo Aneurysm: —Case Report—

Abstract

A 49-year-old female presented with a case of denovo aneurysm which was documented angiographically 10 years after the initial aneurysm rupture. The de novoa neurysm arose as a blister-like aneurysm from a previously normal location 7 years after the first ictus. The denovo aneurysm progressed to a saccular aneurysm and ruptured after another 3 years. We recommend late angiography in high-risk patients to prevent repeat ictus. © 1998, The Japan Neurosurgical Society. All rights reserved.
