Comparative Study of Conventional vs. Frozen Elephant Trunk Surgery for Thoracic Aorta Aneurysms

This retrospective comparative study evaluates the short- and mid-term outcomes of Conventional Elephant Trunk (ET) and Frozen Elephant Trunk (FET) surgical procedures in patients with extensive aneurysmal disease of the thoracic aorta. Conducted by a collaboration of cardiac surgery departments in Italy and Germany, the research aims to fill the gap in existing literature regarding these surgical techniques. Results indicate that both ET and FET are associated with similarly satisfactory outcomes, suggesting both methods are viable options for treating extensive thoracic aorta aneurysms.

  2. BACKGROUND Different surgical and hybrid procedures are available to treat patients with extensive disease of the thoracic aorta. No comparative studies exist comparing short- and mid-term outcomes after extensive aneurysm repair using the Conventional Elephant Trunk (ET) and the Frozen Elephant Trunk (FET) procedures. Here we report our experience

  3. STUDY POPULATION Exclusioncriteria: aortic dissection descending thoracic aorta < 40 mm thoraco-abdominal aneurysm method of brain protection other then antegradeselective brain perfusion

  4. Log Rank= 0.816

  5. CONCLUSION In patients with extensive aneurysms of the thoracic aorta ET and FET procedures were associated with similar satisfactory short- and mid-term outcomes. Longer-term follow up are warranted
