Multicenter Study Observational StudyGiant intracranial aneurysms: natural history and 1-year case fatality after endovascular or surgical treatment.
Clinical evidence on giant intracranial aneurysms (GIAs), intracranial aneurysms with a diameter of at least 25 mm, is limited. The authors aimed to investigate the natural history, case fatality, and treatment outcomes of ruptured and unruptured GIAs. ⋯ Rupture rates for unruptured GIAs were high, and the natural history and treatment outcomes for ruptured GIAs were poor. Patients undergoing SM or EM showed lower case fatality and rupture rates than those undergoing CM. This difference in outcome may in part be influenced by patients in the CM group having been found poor candidates for SM or EM.Clinical trial registration no.: NCT02066493 (clinicaltrials.gov).
