In this podcast, the Editor-in-Chief of JNIS, Robert Tarr, is joined by Ali Alaraj, the corresponding author of the study, "Increased prevalence and rupture status of feeder vessel aneurysms in posterior fossa arteriovenous malformations".

Dr Alaraj, from the Department of Neurosurgery, Neuropsychiatric Institute University of Illinois, Chicago, USA, explains why are posterior cranial fossa arteriovenous malformations (AVMs) more prone to developing associated aneurysms, specifically feeder vessel aneurysms. Feeder vessel aneurysms are more likely to be the source of hemorrhage in the posterior fossa. As such, they may be the most appropriate targets for initial and prompt control by embolization or surgery due to their elevated threat.
