Alternatives to the frozen elephant trunk in acute type A aortic dissection.

Acute type A aortic dissection remains one of the most challenging condition in cardiothoracic surgery, with a high mortality rate. Various improvements and innovations have happened over the years to better the outcome of this lethal condition. The frozen elephant trunk prosthesis has been developed to negate the long-term complications of acute type A aortic dissection, but at the cost of increased morbidity compared to hemiarch replacement. Although hemiarch and total arch replacement seem have less morbidity than the frozen elephant trunk technique, they do not address the long-term complications of the distal dissected aorta. Few surgeons now suggest hybrid aortic arch repair as a solution for acute type A aortic dissection. The long-term results need to be studied in all procedures before standardizing them. Although multiple strategies are evolving, the short-term goal of acute type A aortic dissection has not changed: to save the patient's life. The surgical strategy has to be tailored according to the patient's condition and the surgeon's experience.
