Acute Subdural Hematoma After Intra-arterial Thrombolysis for Acute Ischemic Stroke

—Case Report—

Abstract

A 79-year-old man with a cardiac pacemaker for bradycardia fell down and presented with sudden onset of right hemiplegia and aphasia. Initial computed tomography (CT) showed no cerebral infarction but angiography revealed occlusion of the left middle cerebral artery (MCA). Local intra-arterial thrombolysis with tissue plasminogen activator (tPA; tisokinase, 1,600,000 units) was performed 3 hours after the onset, and the MCA was partially recanalized. Further administration of tPA was suspended because of nosebleed. However, the patient’s neurological findings did not improve. His consciousness gradually deteriorated to coma and quadriplegia with dilation of the left pupil 2.5 hours after thrombolysis. CT disclosed marked mass effect with a left acute subdural hematoma and a small intracerebral hematoma in the left frontal lobe. He underwent urgent craniotomy and removal of the subdural hematoma. The subdural hematoma originated in a frontal cerebral contusion. He died of severe brain edema 2 days after surgery. Acute subdural hematoma is a very rare complication of intra-arterial thrombolysis. Presumably he had suffered head trauma at the first onset. Evidence of head trauma should be considered a contraindication for the use of thrombolytic agents in a patient with acute stroke.
