Complete Shrinkage of the Obliterated False Lumen After Open and Endovascular Chronic Aortic Dissection Stanford Type A Repair.

A 48-year-old man was admitted to our hospital with chronic aortic dissection Stanford Type A. His diagnosis was confirmed by chest multi-detector computed tomography (CT). The patient underwent combined (i.e., hybrid) open and endovascular repair (frozen elephant trunk) in a one-stage operation with moderate hypothermic circulatory arrest and antegrade cerebral perfusion. His postoperative course was uneventful, and he was discharged home on postoperative day 9. At 2-year follow-up, chest CT angiography revealed complete shrinkage of the obliterated false lumen in the distal aortic arch and descending thoracic aorta.
