The annual incidence of lower gastrointestinal bleeding (LGIB) is ∼20.5 in 100,000 in the general Western population and results in 1 to 2% of hospital emergencies. When medical management and endoscopic therapy are inadequate in cases of acute LGIB, endovascular intervention can be lifesaving. In these emergent situations it is important for the interventional radiologist to be well versed in the multidisciplinary preangiographic work-up, the angiographic presentations of LGIB, and the endovascular therapeutic options. We describe a case of LGIB managed with endovascular embolization and detail the angiographic techniques used, followed by a detailed discussion of the various treatment approaches to LGIB.
在西方普通人群中，下消化道出血（LGIB）的年发病率约为每10万人中20.5例，占医院急诊病例的1%至2%。当急性LGIB病例的药物治疗和内镜治疗不足时，血管内介入治疗可能挽救生命。在这些紧急情况下，介入放射科医生熟悉多学科血管造影术前检查、LGIB的血管造影表现以及血管内治疗选择非常重要。我们描述了一例采用血管内栓塞治疗的LGIB病例，并详细介绍了所使用的血管造影技术，随后对LGIB的各种治疗方法进行了详细讨论。
