Case Presentation A 47-year-old male presented with weakness in his left arm upon awakening. Contrast-enhanced computed tomography and transesophageal echocardiography revealed a mobile pedunculated object suggestive of a thrombus arising from the ascending aorta and extending to the left common carotid artery. It was removed under hypothermic circulatory arrest and direct cannulation of the left carotid artery to avoid carotid thromboembolism. Histopathological examination revealed that the object was a thrombus. The patient had an uneventful postoperative course and was discharged 9 days after surgery. Conclusion When a thrombus in the aortic arch extends to the neck arteries, direct cannulation of the neck arteries with selective cerebral perfusion via cervical incision is a useful technique.
