This study aimed to investigate cerebral perfusion, the infarction incidence and risk factors in AAD patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 156 consecutive AAD patients were enrolled and divided into two groups according to whether the aortic arch branches were involved: the affected group (<jats:italic>n<\/jats:italic>= 90) and the unaffected group (<jats:italic>n<\/jats:italic>= 66). Clinical, echocardiographic\/carotid Doppler data and cerebral infarction morbidity were compared between the groups.

Abnormal Doppler waveforms were more common in the affected group (<jats:italic>p<\/jats:italic>&lt;\u00a00.05). Regarding intracranial perfusion, the blood flow volumes (BFVs) of the bilateral internal carotid arteries (ICAs) and right vertebral artery (RVA) in the affected group were significantly reduced (<jats:italic>p<\/jats:italic>&lt;\u00a00.05). The incidence of cerebral infarction in the affected group was significantly higher than that in the unaffected group (35.6% vs. 19.7%,<jats:italic>p<\/jats:italic>= 0.031). Multivariable analysis revealed that age &gt;45 years old, right internal carotid artery (RICA) involvement and reduced left ventricular ejection fraction (LVEF) were significant predictors of perioperative death.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Aortic arch branch involvement is common in patients with AAD and is associated with reduced cerebral blood flow (especially on the right side) and a higher incidence of cerebral infarction.
