Perioperative images. a-b Computed tomography angiography (CTA) before the operation revealing a Stanford type A aortic dissection extending from the aortic root to the bilateral iliac artery. c Transesophageal echocardiography (TEE) showing a mild aortic regurgitation, an enlarged root (47) and ascending aorta (48–52), and an ejection fraction of 69%. d Transesophageal echocardiography (TEE) image. TEE showing the guide wire (arrow-head) present in the true lumen (arrow) of the descending aorta. The false lumen is depicted by a dotted-arrow. e Transesophageal echocardiography (TEE) image. TEE confirming the accurate positioning of the cannulation into the true lumen (arrow). Arrow-head is the false lumen. f The 20 Fr cannulation (Medtronic, arrow) advanced over the guide wire and cannulated into the true lumen of the aortic arch. g Postoperative CTA image revealing the patency of the three-branched vessels and the optimal position of the graft.
