ObjectiveTo identify symptomatic vasospasms as a rare complication after transsphenoidal surgery, with emphasis on management and outcomes.MethodsIn this retrospective study, the medical records of 1997 patients who underwent microscopic transsphenoidal surgery at our hospital between 2008 and 2016 were analyzed regarding postoperative vasospasm events, clinical management, and neurologic outcomes.ResultsFour patients (0.2%) were identified who developed neurologic deficits in the postoperative phase caused by proven vasospasms due to subarachnoid hemorrhage (SAH). All 4 patients were treated according to current state-of-the-art recommendations for SAH-triggered vasospasms and, as ultima ratio, intra-arterial spasmolysis. Nonetheless, all patients developed multilocular ischemic infarctions. Three patients recovered with no or only slight neurologic deficits (2 with a Glasgow Outcome Score [GOS] of 5; 1 with a GOS of 4), and 1 patient died, at 24 days after surgery.ConclusionsAlthough a rare complication, vasospasms after transsphenoidal surgery can lead to severe and multilocular ischemic infarctions with a wide variety of neurologic impairments. This rare complication should be considered in patients with unexpected postoperative neurologic deficits. Computed tomography (CT)/magnetic resonance imaging and (contrast-enhanced) CT/magnetic resonance angiography are appropriate diagnostic tools. Treatment of vasospasms, including the option of intra-arterial spasmolysis, should not be delayed.Copyright © 2017. Published by Elsevier Inc.
