The purpose of this article is to review the roles of angiography, embolization, and various ancillary techniques in evaluating and managing gastrointestinal hemorrhage.
Nonvariceal gastrointestinal hemorrhage typically resolves spontaneously or responds to medical or endoscopic management. Refractory hemorrhage may require angiography and transcatheter intervention. Noninvasive imaging evaluation may be useful for characterizing the bleeding source and confirming the presence of active hemorrhage before angiography. If a bleeding source is angiographically identified, superselective catheterization with embolization is typically effective in controlling hemorrhage while minimizing complications.
本文旨在回顾血管造影、栓塞术以及各种辅助技术在胃肠道出血的评估和治疗中的作用。
非静脉曲张性胃肠道出血通常可自发缓解或对药物或内镜治疗有反应。难治性出血可能需要血管造影和经导管介入治疗。非侵入性成像评估可能有助于在血管造影前确定出血源并确认是否存在活动性出血。如果在血管造影中发现出血源,超选择性导管栓塞术通常可有效控制出血,同时最大限度地减少并发症。
