Measurement of IVCD in CDB with the cutoff value of 13.6 mm can be a simple and useful indicator to predict the detectability of extravasation following TAE procedures. There were no significant differences in other parameters. In the multivariate analysis, IVCD remained significant with an adjusted odds ratio of 1.17. Univariate analysis revealed “usage of anticoagulant” ( p < 0.05) and “larger IVCD ( p < 0.05) on preoperative CTA” to be significant predictors of positive extravasation. TAE was successful in 24 patients in the P-group (96%) and 14 in the N-group (40%) ( p < 0.001). Patient characteristics, laboratory findings, the diameter of the inferior vena cava (IVCD), the diameter of superior and inferior mesenteric veins, and technical outcomes were evaluated. Sixty CDB patients with extravasation on CTA underwent TAE between January 2011 and February 2021 and were divided into extravasation-positive (P-group n = 25) and -negative groups (N-group n = 35) based on the superior or inferior mesenteric angiography. Therefore, to investigate and increase the feasibility of TAE, this retrospective study evaluates the clinical and radiological features related to positive extravasation on angiography.
