Intracranial Vasospasm After Evacuation of Acute Spontaneous Subdural Hematoma

Abstract

Cerebral vasospasm is a well-known entity following aneurysmal subarachnoid hemorrhage. While it has been described in trauma, it has been much less studied. There have been no previous reports of cerebral vasospasm following spontaneous subdural hematoma or after subdural hematoma evacuation. In this case report, we present a 38-year-old otherwise healthy female who suffered an acute spontaneous subdural hematoma. After surgical evacuation of her hematoma, she developed neurologic decline. Computer tomography angiography demonstrated intracranial vasospasm. She was treated with blood pressure augmentation and nimodipine. She went on to make a full neurologic recovery.To our knowledge, this is the first reported case of cerebral vasospasm after acute spontaneous subdural hematoma or after subdural hematoma evacuation, and the patient recovered without sequelae. The promising outcome of this case may provide a framework for future similar cases. Neurosurgeons and intensivists should keep cerebral vasospasm in their differentials for patients who have neurologic decline after craniotomy for acute subdural hematoma and have an otherwise negative scan for new acute abnormality.
