Inconsistent false lumen enhancement predicts late aortic events after hemiarch replacement in Acute type A aortic dissection

The impact of inconsistent enhancement within the patent false lumen on the occurrence of late aortic events remains uncertain. We enrolled a total of 55patients who exhibited a patent false lumen following hemiarch replacement. The Hounsfield unit(HU) measurements in the patent false lumen were obtained at two specific locations: the aortic arch(a) and the descending aorta(b). “The false lumen HU score” was calculated as the absolute value of 1-a/b, representing the discrepancy in Hounsfield units within the patent false lumen.
