In most cases trapping of the ACoA is the best treatment option. Occasionally, bypass surgery is warranted to ensure blood flow to the contralateral anterior cerebral artery (ACA) in cases with one dominant A1. We report a case of an ACoA pseudoaneurysm presenting with delayed subarachnoid hemorrhage following surgical clipping of an unruptured ACoA aneurysm, with a review of the literature %K anterior communicating artery %K distal anterior cerebral artery %K pseudoaneurysm %K side-to-side bypass %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6350030/
