Objectives: In this study, we aimed to investigate the relationship between the diameter of the abdominal aorta with inferior mesenteric artery (IMA) occlusion and intraluminal thrombus (ILT) thickness, as well as the relationship between IMA occlusion and ILT diameter in patients with an abdominal aortic aneurysm (AAA).
Patients and methods: This retrospective study was conducted with 599 AAA patients (515 males, 84 females; mean age: 70.4±9.7 years; range, 26 to 96 years) between January 2015 and December 2020. The patients were grouped according to IMA occlusion. There were 169 (28.2%) patients with an occluded IMA (Group A) and 430 (71.8%) patients with a patent IMA (Group B).
Results: No correlation was found between aneurysm diameter and IMA occlusion. Intraluminal thrombus was more frequent in patients with IMA occlusion than in those without an occlusion (p=0.002). The ILT diameter was found to be extended in Group A (p
