Abstract
We reported a 31-year-old woman with the spontaneous intracranial carotid dissection. She suffered from sudden onset severe headache and transient left homonymous hemianopsia. Angiography demonstrated the tapering of right internal carotid artery at the supraclinoid portion. About 24 hours later she developed progressing left weakness. Sequential angiography demonstrated the occlusion of right internal carotid artery at the same site. Thrombotic embolus caused transient hemianopsia at the onset, and thrombotic occlusion caused progressig hemiparesis. Anticoagulation treatment was effective and her prognosis was good. We think that thrombotic embolism and thrombotic hypoperfusion were two main important pathogenesis of the intracranial internal carotid dissection.
