Background Most studies have focused on evaluating the association between the presence of small bowel vascular lesions (SBVLs) and patients’ comorbidities. Aims We sought to uncover a more fundamental indicator that may predict the presence of SBVLs by considering athero- sclerosis qualitatively and quantitatively. Methods We enrolled 79 consecutive patients with obscure gastrointestinal bleeding who had undergone computed tomog- raphy (CT) and capsule endoscopy or double-balloon endoscopy from January 2015 to June 2017. The SBVL frequency, type, and location, and the relationship between the presence of SBVLs and the patients’ clinical characteristics were evalu- ated. Arterial wall calcification was assessed on unenhanced CT images, and a modified Agatston scoring system was used to determine the abdominal aorta calcium scores. Results Of the 27 (34%) patients with SBVLs, 15 (19%) had type 1a, 12 (15%) had type 1b, and 2 (3%) had type 2a SBVLs. Most of the lesions were located in the jejunum. Cardiovascular disease (P = .017), chronic kidney disease (P = .025), and arteriosclerosis (P = .0036) were associated with the presence of SBVLs. Subsequent multivariate analysis revealed that arteriosclerosis (odds ratio [OR] 7.29; 95% confidence interval [CI] 1.13–143.9) and superior mesenteric artery calcification (OR 16.3; 95% CI 3.64–118.6) were independent predictors of
