Objective: The aim of our study was to observe the typical diameter of the dissected ascending aorta at the time of dissection, as well as any potential correlation between the diameter of the dissected aorta and body mass index or body surface area.

Methods: This study examines the cohort of patients who had emergent surgical procedures for ascending aortic dissection at our medical center between March 2014 and July 2021. The whole patient population consisted of 62 individuals. The study included the examination of the aortic root, arch, ascending and descending aortic diameters in all individuals. The study documented cases of valvular illness, surgical procedures, Cardiopulmonary Bypass (CPB) time, and Total Circulatory Arrest (TCA) time. The patients' Body Surface Area (BSA) and Body Mass Index (BMI) were derived by using their height and weight measurements.

Findings: The majority of the patients in the study were male, and the mean age of all the patients was 59.23 ± 11.74 (61.5) years. The mean diameter of the ascending aorta was determined to be 51.23 ± 7.75 (50). The body surface area (BSA) was measured to be 1.9 ± 0.19 (1.89) m², but the body mass index (BMI) was calculated to be 26.93 ± 4.2 (26.15) kg/m². At the time of dissection, there was no statistically significant link seen between body surface area (BSA) or body mass index (BMI) and ascending aortic size.

Results: The majority of the patients in the study were male, and the mean age of all the patients was 59.23 ± 11.74 (61.5) years. The mean diameter of the ascending aorta was determined to be 51.23 ± 7.75 (50). The body surface area (BSA) was measured to be 1.9 ± 0.19 (1.89) m², but the body mass index (BMI) was calculated to be 26.93 ± 4.2 (26.15) kg/m². At the time of dissection, there was no statistically significant link seen between body surface area (BSA) or body mass index (BMI) and ascending aortic size.

Conclusion: The average ascending aortic diameter at the time of dissection is around 50 mm. The 55 mm aortic size may not be the definitive threshold for elective surgery. There is not a significant relationship between the measured diameter of the dissected ascending aorta and the individual's body surface area (BSA) or body mass index (BMI).
