Equations Estimating the Pre-Dissected Diameter of the Ascending Aorta for Acute Type A Aortic Dissection

To date, there has been no unianimous method to calculate the diameter of the aorta prior to the occurence of type A aortic dissection. In this study, reseachers from Osaka, Japan, reported the efforts in developing equations for estimating the predissection diameters of the ascending aorta and the arch based on postdissection measurements. These equations have the potential of determining the size of stent grafts in the management of patients with type A dissection.
