External carotid artery-to-petrous internal carotid artery radial artery graft bypass for giant high cervical aneurysm
Objective To investigate the treatment strategy of giant high cervical extracranial internal carotid artery aneurysm(EICAA).Methods The clinical data,surgical strategy and follow-up of one case were retrospectively ana-lyzed,and the relevant literature was reviewed.Results A 52-year-old male was admitted to hospital due to"intermit-tent cough for 1 year,aggravation and headache for 2 months".DSA showed a giant right high cervical EICAA.An external carotid artery-radial artery graft-internal carotid artery petrous segment bypass combined with aneurysm trapping was performed.There was no new cerebral ischemia or cerebral infarction after surgery,no new neurological dysfunction,and the original symptoms were significantly improved.Conclusion Cerebrovascular bypass surgery is still one of the effective treatment strategies for large internal carotid artery aneurysms with high cervical segments,and internal carotid artery bypass grafting in the external carotid artery-radial artery-petrosal segment can effectively deal with such lesions.
