Purpose: This study examines the relationship between Body Mass Index (BMI) and radiation exposure during elective Endovascular Aneurysm Repair (EVAR) for abdominal aortic aneurysms (AAA). Understanding this correlation may help optimise surgical practices and minimise radiation-related risks. Methodology: A retrospective review of all the patients who received an elective EVAR at St George Hospital in 2023 and 2024 was performed. Data on age, BMI and total radiation dose were collected for each case. Length of ICU and hospital admission were also compared between normal weight, overweight, and obese patient groups. Results: There were 22 patients (21 male, 1 female) who underwent elective EVAR in 2023/24. The median age was 75.5 years (range 60-93), median radiation exposure was 13583 μGym2 (range 4988- 110686) and median BMI was 27.94 (range 21.13- 41.4). There were 7 obese patients (BMI >30), 7 overweight (BMI 25-30) and 8 normal weight (BMI 20-25). There was no significant correlation between length of ICU stay (r= 0.0191) or length of hospital stay (r=0.0403) and BMI. No correlation between age and radiation exposure (R = 0.03281). A significant positive correlation was found between BMI and radiation dose (R = 0.7522, p <0.01). Conclusion: Higher BMI is linked to a significantly increased radiation exposure during elective EVAR. This has major implications for planning treatment in obese patients in order to optimise patient safety and minimise occupational exposures. This should be investigated further across a wider patient population.
