CCAD, due to extension from aortic arch dissection, has a low risk of subsequent stroke after the initial event. Based on current data, there is little evidence to suggest that aortic origin CCAD requires repair in the absence of recurrent symptoms, regardless of the degree of stenosis or false-lumen patency. Recommended optimal medical therapy includes either aspirin or anticoagulation for 6 months after initial presentation. Additional longitudinal studies are needed.
