[Reconstruction of the left common carotid artery for dissective occlusion detected by intra-operative ultrasonography]

We describe a case of Stanford type A acute aortic dissection. Replacement of the ascending aorta and aortic arch was performed using an "arch 1st technique". Following the completion of replacement, hypotension of the left superficial temporal artery pressure was detected. Ultrasonography revealed dissection of the left common carotid artery (LCCA) and compressive occlusion of the true lumen. Reconstruction of the LCCA was performed in the neck. The patient did well after the operation without any neurological abnormalities.
