Abstrakt:	Objective: Stanford type A acute aortic dissection (AAD) is associated with carotid artery dissections (CADs). We report two cases of carotid artery stenting (CAS) for symptomatic CAD after ascending aortic replacement (AAR) for AAD. Case Presentation: Case 1: A 51-year-old man with AAD was transferred to our institute. He had no notable paralysis symptoms on initial presentation. However, after AAR for AAD was performed, left paralysis developed within a few hours. Emergency angiography revealed right CAD and pseudo-occlusion. CAS was performed successfully using intravascular ultrasound (IVUS). He was transferred to a rehabilitation hospital with a modified Rankin Scale (mRS) score of 2.Case 2: A 55-year-old man underwent AAR for AAD, but asymptomatic left CAD remained. Two weeks after the operation, he presented with slight signs of aphasia. Aspirin was prescribed and follow-up was performed, but his symptoms did not improve. He underwent magnetic resonance imaging in our department, which revealed acute cerebral infarction on the left pars opercularis and an artery-to-artery embolism from CAD. CAS was performed via the retrograde approach with direct puncture of the normal left common carotid artery using IVUS. He was discharged with no complications and a mRS score of 1. Conclusion: IVUS can be useful for CAS to confirm the true lumen and extension of long CAD lesions developing from AAD. Competing Interests: The authors declare no conflict of interest.
