[Therapy of cerebral aneurysms and arteriovenous vascular malformations in hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber disease)]

Abstract

Little is known about the course of cerebral aneurysms in hereditary hemorrhagic teleangiectasia (Rendu-Osler-Weber's disease). Thus, therapeutic decisions are often difficult. For the first time, we report the successful embolization of an arteriovenous fistula and multiple aneurysms of the posterior inferior cerebellar artery (PICA) of a patient with Rendu-Osler-Weber's disease after subarachnoid hemorrhage. Two years later she suffered another severe intracranial hemorrhage. Angiography revealed an aneurysm in the same artery (PICA), which spontaneously disappeared within 2 months. Spontaneous regression of aneurysms in Rendu-Osler-Weber's disease has not been reported before.
