title: [Persistent cerebral malperfusion following central aortic repair for acute aortic dissection involving the right carotid artery; efficacy of direct carotid artery cannulation].
abstract: A 61-year-old man suddenly developed transient left hemiplegia and consciousness disturbance. Computed tomography showed acute Stanford type A aortic dissection. Dissection affected the entire right common carotid artery, and its false lumen extremely compressed the true lumen. The right common carotid artery, along with the right femoral and the left axillary arteries, was used as an inflow of cardiopulmonary bypass during emergency surgery. The ascending aorta that included a large intimal tear was replaced. However, systemic reperfusion either through the femoral artery or through a side branch of vascular prosthesis failed to restore the right cerebral blood flow due to persistent true lumen obstruction by the expanded false lumen in the innominate artery. Therefore, ascending aorta-right carotid artery bypass using that side branch was performed immediately. Though temporary cerebral malperfusion could cause dismal outcome, direct carotid artery cannulation played a key role in this successfully-treated patient.
