To compare the perioperative results of frozen elephant trunk (FET) vs. traditional elephant trunk (ET) procedures for aortic arch repair. 390 individuals had aortic repair with elephant trunk reconstruction between 2002 and 2018 at 9 facilities: Aortic dissection affected 37% of patients who received a FET (mean age: 65+/-13 years, 30% female), while 43% of patients who received an ET (mean age: 63+/-13 years, 37% female) experienced aortic dissection. In-hospital mortality, stroke, and spinal cord injury were among the outcomes of interest (SCI).
