Morphology of the ascending aorta: a study on 114 Chinese patients

ABSTRACT Purpose: This study aimed to investigate the morphological characteristics of ascending aortic dissection in detail. Materials and Methods: The ascending aorta was morphologically assessed in a consecutive series of patients between January 2009 and October 2014. A new assessment and evaluation method was used to describe 114 patients with ascending aortic dissection. Results: A large difference was found in the degree of curvature between the ascending aorta with and without dissection. The shape of the former was straighter and steeper (control group R, 47.46 ± 6.40 mm; experimental group R, 59.70 ± 10.27 mm, P Conclusion: The morphological features of the ascending aorta after dissection and the correlations among dissections, entries, and related factors were found.
