The source of gastrointestinal hemorrhage is found in 94-95% of patients who undergo radiologic and/or endoscopic examinations of the upper or lower bowel. However, the exact presurgical localization of small bowel bleeding sites, which account for the other 5-6%, remains diagnostically difficult. We describe a previously reported and uncommon but useful angiographic technique used in conjunction with surgery which assists in this localization.
在接受上消化道或下消化道放射学和/或内镜检查的患者中，94% - 95%可找到胃肠道出血的来源。然而，占另外5% - 6%的小肠出血部位的术前准确定位在诊断上仍然困难。我们描述一种先前报道的、不常见但有用的血管造影技术，该技术与手术联合使用有助于这种定位。
