New research: Treatment advancements help reduce mortality from unruptured brain aneurysms

Mortality rates after treatment of unruptured intracranial aneurysms have substantially decreased in the past decade, according to new findings presented today at the Society of NeuroInterventional Surgery’s (SNIS) 17th Annual Meeting. The study, Trends in Mortality and Morbidity after Treatment of Unruptured Intracranial Aneurysm in the United States, 2006-2016, analyzed data from 21,609 patients in the Nationwide Inpatient Sample (NIS) database across a 10-year period. The research compares two treatments for unruptured intracranial aneurysms: microsurgical clipping and endovascular embolization.
