Fig 2 Distal landing zone open fenestration procedure. (A) Heart retracted cephalad to expose distal descending aorta through posterior pericardium or left pleural space. (B) Dissection flap excised through anterior longitudinal aortotomy. Intraoperative view of chronic dissection flap through aortotomy before (blue arrow in B) and after (blue arrow in C) open fenestration.

Fig 3 Chronic aorta with aneurysm after first-stage repair. The arrow in the illustration in panel (A) marks planned distal landing zone for second-stage endovascular completion. Axial computed tomographic scan of modified distal landing zone preoperatively (B) and postoperatively (C). Note the radiopaque metallic clip marking the modified distal landing zone.
