Nearly 50 years ago, catheter angiography was introduced as a means of both diagnosing and treating nonvariceal upper gastrointestinal bleeding. Technological advances and innovations have resulted in the introduction of microcatheters that, using a coaxial technique, are capable of selecting third-order arterial branches and of delivering a wide array of embolic agents. This article reviews the imaging diagnosis of nonvariceal upper gastrointestinal bleeding, the techniques of diagnostic and therapeutic angiography, the angiographic appearance of the various etiologies of nonvariceal upper gastrointestinal bleeding, the rationale behind case-specific selection of embolic agents as well as the anticipated outcome of transcatheter arterial embolization.
近50年前，导管血管造影术被引入作为诊断和治疗非静脉曲张性上消化道出血的一种手段。技术进步与创新带来了微导管的问世，这些微导管采用同轴技术，能够选择三级动脉分支并输送多种栓塞剂。本文综述了非静脉曲张性上消化道出血的影像诊断、诊断性和治疗性血管造影技术、非静脉曲张性上消化道出血各种病因的血管造影表现、针对具体病例选择栓塞剂的依据以及经导管动脉栓塞术的预期结果。
