Thoracic endovascular aortic repair (TEVAR) is considered a safe and feasible technique especially in complex cases. One of
the most catastrophic complications during follow up is modular disconnection. When modular disconnection occurs, endoleak
is massive and risk of mortality is dramatically increased. We report our findings during follow up of a 49 years male underwent
ascending aorta replacement for acute Type A aortic dissection and subsequently surgical replacement of aortic arch and TEVAR
due to huge enlargement of the thoraco-abdominal false lumen. Our analysis suggest.com more attention on topographic changes of
the prostheses to prevent this fatal complications.
