A ruptured de novo anastomotic aneurysm shortly after superficial temporal artery–to–middle cerebral artery bypass surgery in a patient with moyamoya disease: illustrative case
This case represents the shortest documented interval between combined bypass surgery and a ruptured de novo anastomotic aneurysm. Genetic predisposition, inflammatory processes, and hemodynamic alterations likely contribute to aneurysm formation. Standardized postoperative surveillance and individualized management strategies are essential to mitigate these risks. https://thejns.org/doi/10.3171/CASE25429.
