Massive brain aneurysm device registry launches to find best treatment
NCT ID NCT06174727
First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study looks back at medical records of up to 5,000 adults who had a brain aneurysm treated with special mesh tubes called flow diverters. Researchers want to see how well these devices work and how safe they are by checking things like successful placement, complications, and recovery. The goal is to learn which device works best for different types of aneurysms.
