一位86岁的男性患者在血液检查中表现为频繁的便血和轻度贫血。结肠镜检查显示下直肠粘膜下肿瘤样病变。CT和MRI显示有血流进入病灶，但未见肿瘤成分。直肠上动脉及左髂内动脉造影显示血管增生及病灶。因此诊断为直肠动静脉畸形。如果动静脉畸形出血失控，手术切除是必要的。然而，由于患者的年龄，我们进行了经导管动脉栓塞术，不需要腹部会阴切除术。从直肠左上动脉、直肠中动脉和直肠下动脉进行栓塞，以控制出血，避免手术。栓塞后在我院随访10个月，无复发。(C) 2020作者：s . Karger AG出版，巴塞尔
An 86-year-old man who presented with frequent hematochezia with mild anemia on blood tests was admitted to our hospital. Colonoscopy exhibited a submucosal tumor-like lesion in the lower rectum. CT and MRI showed blood flow into the lesion, but not tumor component. Angiography of the superior rectal artery and left internal iliac artery showed vascular hyperplasia and nidus. Thus, rectal arteriovenous malformation was diagnosed. If bleeding from arteriovenous malformation was out of control, surgical resection was necessary. However, due to the age of the patient, we performed transcatheter arterial embolization and abdominoperineal resection was not needed. Embolization from the left superior rectal artery, middle rectal artery and inferior rectal artery was performed to control the bleeding and to avoid surgery. After embolization, he was followed up for 10 months in our hospital without recurrence. (C) 2020 The Author(s) Published by S. Karger AG, Basel
