[Vertebral arterial dissection with subarachnoid hemorrhage after ischemic onset].
A case is reported of the vertebral arterial dissection presenting initially with cerebellar infarction, and which subsequently occurred with subarachnoid hemorrhage 14 days later. A 75-year old male was admitted because of vertigo and ataxia. MR T2-weighted imaging showed a hyperintensity areas on the left cerebellar hemisphere and MR angiography showed multiple stenotic lesions in the left vertebral artery. We diagnosed his illness as dissection of the left vertebral artery and antiplatelet therapy and the blood pressure control were carried out. Fourteen days after the onset, the patient complained of sudden onset of headache and subarachnoid hemorrhage was confirmed on CT scan. Proximal clip occlusion of the left vertebral artery and OA-PICA anastomosis was carried out immediately. The patient was discharged with slight truncal ataxia. We evaluated the features of this vertebral arterial dissection presenting with subarachnoid hemorrhage after ischemic stroke with reference to another reported cases.
