The frozen elephant trunk technique is reviewed as an option for treating acute type A aortic dissection involving the arch and thoracic aorta, evaluating short- and long-term outcomes.
Does the frozen elephant trunk (FET) technique improve short- and long-term outcomes compared to conservative approaches in patients with acute type A aortic dissection?
This review summarizes contemporary literature on the use of the frozen elephant trunk technique for acute type A aortic dissection repair.
Acute type A aortic dissection (ATAAD) is an indisputable emergency with very poor outcomes without surgical treatment. Although the aortic arch is often involved in the aortic dissection, its optimal management during surgical therapy remains uncertain. A conservative tear-oriented approach has traditionally been adopted, limiting the procedure to the ascending aorta (or hemiarch) replacement. However, dilation of the residual dissected aorta and subsequent rupture may occur, requiring further intervention in the future. In the last two decades, the frozen elephant trunk (FET) technique has become a valid and attractive option to treat aortic disease when the arch and the thoracic aorta are involved, both in elective and in emergency settings. Here, we report a review of the contemporary literature regarding the short- and long-term outcomes of the FET technique in ATAAD repair.
Chivasso et al. (Sat,) conducted a review in Acute type A aortic dissection (ATAAD). Frozen elephant trunk (FET) technique was evaluated on Short- and long-term outcomes. The frozen elephant trunk technique is reviewed as an option for treating acute type A aortic dissection involving the arch and thoracic aorta, evaluating short- and long-term outcomes.
