Biliary tract bleeding is an unusual cause of upper gastrointestinal hemorrhage. Rupture of hepatic artery aneurysms is one of the least common etiologies of hemobilia. Both cholescintigraphy and [99mTc]red blood cell scintigraphy are useful in the diagnosis of this rare disorder. The combination of focal obstruction on cholescintigraphy and intermittent visualization of the major bile ducts on red blood cell scintigraphy should suggest the diagnosis of hemobilia and prompt an angiogram to determine the cause.
胆道出血是上消化道出血的一种罕见原因。肝动脉瘤破裂是胆道出血最不常见的病因之一。胆管闪烁显像和[99mTc]红细胞闪烁显像对诊断这种罕见疾病均有帮助。胆管闪烁显像上的局灶性梗阻与红细胞闪烁显像上主要胆管的间歇性显影相结合，应提示胆道出血的诊断，并促使进行血管造影以确定病因。
