title: [Persistent Disturbance of Consciousness after Clipping of an Unruptured Cerebral Aneurysm due to Pseudohypoxic Brain Swelling].
abstract: A patient developed persistent disturbance of consciousness after uneventful clipping of an unruptured cerebral aneurysm under general anesthesia. Pseudohypoxic brain swelling (PHBS) was suspected because computerized tomography (CT) and magnetic resonance imaging (MRI) revealed diffuse brain swelling, especially in the bilateral basal ganglia and thalami. Steroid pulse therapy in addition to antiedematous drugs and anticonvulsant improved the consciousness. Anesthesiologists should pay attention to PHBS in a case of persistent disturbance of consciousness after uneventful craniotomy.
