Lawrence MD, Brian G. DeRubertis MD 2 Type I: 58% Type II:24% This arch elongation and the broadness of the arch can be quantified by placing an asculating circle over the region of maximum curvature, then calculating the radius of this curvature. 3 Strong correlation between age and aortic arch ROC (R2=0.60, p<0.0001) 4 ASC. DIAM.=1.96+0.0185Age P<0.001 R2 = 0.26 3 Type III: 18% DESC. DIAM.=1.39+0.012Age P<0.001 R2 = 0.27 1 Descending Thoracic Aorta Ascending Thoracic Aorta Age and Aortic Diameters (non-aneurysmal patients) Arch type. which is known to impact the difficulty of endovascular interventions in the aortic arch, was assessed in all patients and was classified as type I, type II, or type III, depending on whether the branch vessels originated above, between, or below the greater and lesser curvatures of the arch. Type I was most common, occurring in 58% of patients, while type III occurred in only 18%.
