    BackgroundAnterior inferior cerebellar artery (AICA) aneurysms present a challenge for neurosurgeons and neurointerventionalists alike.MethodsCases of AICA aneurysms managed with endovascular flow diversion at our institute are reviewed with their angiographic outcomes.ResultsBoth direct and indirect flow diversion provide complete aneurysm occlusion at follow-up. We propose a stratified method of approaching AICA aneurysms based on location, rupture status, and neck size.ConclusionsCareful evaluation of preoperative parameters is paramount in deciding between a surgical or a neuroendovascular approach. Low-profile stents in the future may assist in direct flow diversion of AICA trunk aneurysms. In addition, neurosurgeons need to be well versed in endovascular approaches.Copyright © 2023 Elsevier Inc. All rights reserved.
