The rationale and design of the Giant Intracranial Aneurysm Registry: a retrospective and prospective study.

Abstract

Giant intracranial aneurysms have a poor prognosis mainly due to their high risk of rupture. Because their incidence is low, clinical trial evidence for adequate treatment is lacking. The Giant Intracranial Aneurysm Registry is designed to document current treatment strategies in giant aneurysm care and to monitor the course of the disease over five-years. It aims to evaluate the hypothesis that all three possible branches of therapy (conservative/endovascular/surgical) lead to equal rupture rates.
