Despite visceral angiography and radiolabeled gastrointestinal scintigraphy, the localization of gastrointestinal bleeding can still be a challenge. Even preoperative localization with visceral angiography is no guarantee of successful intraoperative localization or subsequent pathological confirmation. We report a case of obscure gastrointestinal bleeding of small bowel origin, which was localized intraoperatively by fluorescein injected via a superselectively placed catheter.
尽管有内脏血管造影术和放射性核素标记的胃肠道闪烁扫描术，但胃肠道出血的定位仍然可能是一项挑战。即使是通过内脏血管造影术进行术前定位，也不能保证术中成功定位或随后的病理证实。我们报告一例源于小肠的不明原因胃肠道出血病例，该病例通过经超选择性放置的导管注射荧光素在术中实现了定位。
