Summary
The frozen elephant trunk (FET) technique provides a durable solution for complex aortic arch repair, especially in younger patients with heritable thoracic aortic disease (HTAD) requiring reoperations. This method integrates valve-sparing aortic root replacement and total arch repair for comprehensive treatment.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Disease Management
Background:
- The frozen elephant trunk (FET) technique is a key treatment for complex aortic arch and descending aorta pathologies.
- While endovascular options suit limited life expectancy, FET offers a sustainable solution for younger patients with heritable thoracic aortic disease (HTAD) and post-dissection, often necessitating reoperation.
- Many patients require concomitant aortic root or cardiac procedures, complicating surgical planning.
