Acute hypertensive subdural hematoma from arterial rupture shortly after the onset of cerebral subcortical hemorrhage: leakage of contrast medium during angiography
H Arai
A case is reported of a Japanese female in whom acute right subdural
hematoma due to the spontaneous rupture of the posterior branch of the
right central artery occurred shortly after the onset of hypertensive
subcortical hemorrhage of the right occipital lobe. Marked hypertension
persisted. There was no evidence of subdural hematoma when a small
collection of extravasated contrast medium from the cortical artery was
revealed during right carotid angiography. Soon thereafter the patient
became comatose and developed decerebrate posturing. Computed tomography
scan was done immediately and a large subdural hematoma was identified.
There was a gratifying response to prompt recognition and neurosurgical
therapy of the condition. The pinpoint rupture of the cortical artery is
considered to have occurred during marked hypertension. Previous 39 cases
with subdural hematomas from arterial rupture, 27 traumatic and 12
spontaneous nontraumatic, are reviewed.
