It has been well-known that technetium-99m-human serum albumin-diethylenetriaminepenta-acetic acid (99mTc-HSAD) scintigraphy is useful for diagnosis of the localization of the gastrointestinal arterial or venous bleeding. In this report, we describe a case of venous bleeding from capillary hemangioma of the ileum end detected by 99mTc-HSAD scintigraphy. This patient was a 9-year-old girl with severe anemia. Gastrointestinal bleeding was suspected from her clinical course and laboratory tests. Immediately after melena occurred, 99mTc-HSAD scintigraphy showed the extravasation of RI suggesting gastrointestinal bleeding in the ileum end. Abdominal angiography immediately after 99mTc-HSAD scintigraphy, however, could not show the extravasation of contrast agent. Because the condition of the patient became worse, laparotomy was performed on the basis of 99mTc-HSAD scintigraphy findings. At surgery, venous bleeding from capillary hemangioma in the ileum end was observed. It was suggested that 99mTc-HSAD scintigraphy was very useful for identifying the gastrointestinal venous bleeding.
众所周知,锝-99m-人血清白蛋白-二乙烯三胺五乙酸(99mTc-HSAD)闪烁扫描术对于诊断胃肠道动脉或静脉出血的部位很有用。在本报告中,我们描述了一例通过99mTc-HSAD闪烁扫描术检测到的回肠末端毛细血管瘤引起的静脉出血病例。该患者是一名患有严重贫血的9岁女孩。从她的临床病程和实验室检查怀疑有胃肠道出血。在出现黑便后立即进行的99mTc-HSAD闪烁扫描术显示放射性示踪剂外渗,提示回肠末端有胃肠道出血。然而,在99mTc-HSAD闪烁扫描术后立即进行的腹部血管造影未能显示造影剂外渗。由于患者病情恶化,根据99mTc-HSAD闪烁扫描术的结果进行了剖腹手术。手术中观察到回肠末端毛细血管瘤引起的静脉出血。提示99mTc-HSAD闪烁扫描术对于识别胃肠道静脉出血非常有用。
