Assessing Occlusion and Recovery in Large and Giant Intracranial Aneurysms: A Comparative Retrospective Study of Flow Diversion Alone Versus Combined With Coiling and the Role of Packing Density

In this study, FD with minimal coiling at a PD of 12% to 14% significantly enhanced complete aneurysm occlusion and functional recovery in patients with large aneurysms compared with using FD alone. PD above 12% to 14% threshold up to 26% impact on occlusion rates is particularly pronounced in very large or giant aneurysms.
