Consequently, a strictly diameterīased screening for patients at risk for TBD would be In theĬontrol group, no patient had a diameter %5 mm in theĮntire thoracic aorta. (D8), respectively, out of the 96 patients with TBD. However, with respect to the relevant guidelines, it appears interesting that even in theĭissected distal arch (D7) and descending aorta (D8), aĭiameter of %5 mm was reached in just one (D7) and four Consequently, the prognostic values of these parameters remain unknown.

With TBD, but the retrospective character of this study did Particularly in non-dissected aortic arches, to be associated Increased diameter and length parameters were found, The TBD group represented a cohort of patients who had a diagnosis of TBD That the classification of these retrograde (proximal) dissections is somewhat unclear.2 Also excluded were all patients with previously known connective tissue disordersĪnd with previous aortic surgery.

Were used to examine aortic diameters at defined landmarks and aortic segment lengths. Retrospectively examined using three dimensional computed tomography imaging. Methods: The aortic morphology of a healthy control group (n ¼ 236) and patients with TBD (n ¼ 96) was The role of both aortic elongation and dilatation in patients with TBD was evaluated. Objective/Background: Aortic elongation has not yet been considered as a potential risk factor for Stanford typeī dissection (TBD).
