Ascending Aortic Diameter at the Time of Dissection and its Relationship with Body Mass Index and Body Surface Area

Objective: During our experience in aortic dissection surgery, we noticed that the dissected aortic diameter in usual is less than 55 mm. So we designed this research to find the mean diameter of the ascending aorta at the time of dissection and any relation between the diameter of the dissected aorta and body mass index/body surface area.

Methods: We have studied the patients who had undergone urgent operations for ascending aortic dissection in our centre from March 2014 to July 2021. The total number of patients was 62. All the patients were investigated for the size of the aortic root, arch, and ascending, descending aortic diameter. Valvular disease, operative surgical procedure, total Cardiopulmonary Bypass (CPB), cross-clamp, and Total Circulatory Arrest (TCA) were also recorded. Body Surface Area (BSA) and Body Mass Index (BMI) were calculated from the height and weight of the patients.

Results: Most of the patients were males, and the average age of all the patients was 59.23 ± 11, 74 (61.5) years. The average diameter of the ascending aorta was 51.23 ± 7.75 (50). BSA was 1.9 ± 0.19 (1.89) m² while BMI was 26.93 ± 4.2 (26.15) kg/m². There was no significant correlation between BSA/BMI and ascending aortic size at the time of dissection.

Conclusion: The mean ascending aortic diameter at dissection time is about 50 mm. The 55 mm aortic size maybe not is the certain borderline for elective surgery. There is no direct relationship between the dissected ascending aortic diameter and BSA or BMI.
