Retrograde extension of common carotid artery dissection into the aortic arch

Abstract

Internal carotid artery dissection is an important cause of stroke in young patients. A common carotid artery dissection is a relatively rare condition. Most dissections of the internal carotid arteries heal spontaneously with conservative treatment. However, the natural history of the common carotid artery dissection is unknown. We report a case of common carotid artery dissection followed by retrograde extension into aortic arch dissection.

Type A aortic dissection secondary to a left common carotid artery dissection

“…In our case the CCAD preceded the Type A aortic dissection by 3 weeks. The first case description of retrograde extension of a CCAD was documented by Yoshioka et al in 2011 [3] . In their case the time gap between common carotid dissection and aortic dissection was 3 months.…”
