Key result
The frozen elephant trunk technique has evolved as a standard treatment for complex thoracic aortic pathologies in experienced centers, with modifications such as proximalization to arch ZONE 2.
The frozen elephant trunk technique has evolved as a versatile surgical option for complex thoracic aortic pathologies, with prosthesis choice and anastomosis zones tailored to specific indications such as acute dissections versus degenerative aneurysms.
Complex pathologies of the thoracic aorta have always been a challenge in cardiac surgery, since they may require multiple operations with high peri-operative risks and hospital mortality rates. The technique and the devices developed during recent decades, such as the introduction of the Elephant Trunk and branched graft techniques, have improved the possibility of the repair in such patients, simplifying the procedures (1,2). The frozen elephant trunk technique (FET) is the latest evolution in this field (3).
