“…In addition, we found a higher ratio of IAN/AAA in the rAAA group. This nding is in line with Lorandon et al [11] describing a higher ratio of AAA/pararenal aortic diameter in the rAAA group. Last, analysis of different aortic angles in axial, coronal or sagittal reconstructions could not demonstrate signi cant differences between the rAAA and the non-ruptured AAA group; however, Kimura et al [12] found both aspect ratio (vertical diameter divided by the horizontal diameter) and llet radius (curve of the joint between the aorta and the aneurysm) signi cantly lower in the ruptured compared to the non-ruptured group.…”

Purpose to determine potential clinical and computed tomography (CT) imaging predictors for abdominal aortic aneurysm (AAA) rupture based on a comparative analysis of patients presenting with large (> 6.5 cm diameter) unruptured AAA (uAAA) and patients presenting with ruptured AAA (rAAA) respectively. Methods consecutive patients presenting with large unruptured or rAAA and having undergone a contrast-enhanced CT at admission between January 2005 and June 2019 were included. Patients’ demographics and CT-imaging characteristics were collected from the institutional electronic medical records. Both patient groups were compared using Fisher’s exact test for categorical variables and the Mann-Whitney U test for continuous variables. Results we included 101 patients, of which 57 patients presenting with a rAAA and 44 patients with a large, uAAA. Patients in the large, uAAA group were younger, mean age of 76 years vs 83 years (P < 0.001), had less coronary artery disease (47.6% vs 72.5%; P = 0.026) and had a lower left common iliac artery to maximum aneurysm diameter ratio (0.15 vs 0.18; P = 0.034), a lower sum of right + left common iliac artery to maximum aneurysm diameter ratio (0.31 vs 0.39; P = 0.028) and a lower infrarenal neck to maximum aneurysm diameter ratio (0.29 vs 0.35; P = 0.039). Conclusion patients with large, uAAA’s were younger with less coronary artery disease and presented with lower ratio of right + left common iliac artery to maximum aneurysm diameter as well as a lower ratio of infrarenal neck to maximum aneurysm diameter on CT-imaging compared to patients with rAAA.
