Description
Summary:We report the usefulness of cone-beam computed tomography angiography (CBCTA) and automated vessel detection (AVD) software in transcatheter arterial embolization in two cases of obscure ascending colonic diverticular hemorrhage after unsuccessful endoscopic clipping. Arteriography of the superior mesenteric artery demonstrated no active bleeding. Considering the positional relationship of the clips, we could narrow the responsible vessel down to two candidates but could not definitively identify the responsible vessel. We performed CBCTA at the marginal artery of the right colic artery, and the responsible branch was identified using AVD. The responsible vessel could be embolized, and hemostasis was achieved with no ischemic complications. CBCTA and AVD software for colonic diverticular hemorrhage after endoscopic clipping were useful for identifying the responsible vessel and in performing selective embolization.
