Aortic Arch Angle and Aortic Arch Morphometry in COVID 19 Patients: A Radioanatomical Study

Aim: In endovascular surgery, knowing the morphometry of the aortic arch increases the success of surgery. The aim of this study was to examine the angle and morphometry of aortic arch in COVID 19 patients and to compare these with healthy individuals to find out the effect of the disease on the vessel. Material and Methods: A total of 120 individuals - 60 COVID 19 (30 females, 30 males) patients and 60 healthy (30 females, 30 males) individuals participated in the study. In the study, the parameters of aortic arch angle (AAA), aortic arch diameter (AAD), aortic arch (AA) branches of brachiocephalic trunk diameter (BTD), left common carotid artery diameter (LCCAD), left subclavian artery diameter (LSAD), transverse superior thoracic aperture length (TR-STAL) and anteroposterior superior thoracic aperture length (AP-STAL), transverse inferior thoracic aperture length (TR-ITAL) and anteroposterior inferior thoracic aperture length (AP-ITAL) were measured from thoracic computed tomography images. Results: As a result of the study, when female and male patients with COVID-19 were compared, LCCAD, LSAD, AP-ITAL, TR-ITAL values were found to be higher in favour of male patients. While Proximal AAD, BTD, LCCAD and LSAD values were higher in female patients with COVID 19 when compared with control group female patients, Proximal AAD, BTD, LCCAD, LSAD, AP-STAL, TR-STAL, AP-ITAL, TR-ITAL values were higher in male patients with COVID 19 when compared with control group male patients. When the measurements of COVID 19 and control group individuals were compared, Proximal AAD, BTD, ACCS, LSAD, TR-STAL, AP-ITAL and TR-ITAL values were found to be higher in favour of COVID 19 patients. Conclusion: COVID 19 is an important disease that causes dilatation of the AA and its branches. We think that diseases that can change oxygen saturation such as COVID19 can change aortic morphology.
