Vasospasm following resection of olfactory groove meningiomas via orbitozygomatic craniotomy: illustrative cases

Postoperative vasospasm is an important but often overlooked complication following anterior skull base meningioma resection. Early recognition and aggressive management with intra-arterial therapy can mitigate ischemic complications. Neurosurgeons should maintain high suspicion for vasospasm in the setting of neurological decline after tumor resection near the circle of Willis. https://thejns.org/doi/10.3171/CASE25641.
