我们在此报道一名 38 岁男性被发现患有直肠动静脉畸形 (AVM) 的病例。患者因肛门新鲜出血和全身不适而入院。钡灌肠检查显示直肠有轻微隆起的病变，随后选择性直肠上动脉造影显示直肠上动脉周围区域有动静脉畸形，推测这就是肛门出血的原因。结肠镜检查发现直肠左后壁、肛缘上方 3 厘米处有粘膜下肿瘤样病变。通过夹闭标记边界后，对病变进行经肛门切除。组织学检查显示粘膜下层不规则扩张的动静脉聚集。患者术后病程良好，术后选择性肠系膜下动脉造影未见残留 AVM。自从他手术后，2个齿轮都没有复发的迹象。
We report herein the case of a 38-year-old man found to have a rectal arteriovenous malformation (AVM). The patient was admitted to our hospital for investigation of fresh anal bleeding and general malaise. Barium-enema examination showed a slightly elevated lesion in the rectum, and a selective superior rectal angiogram subsequently revealed an AVM in the peripheral region of the superior rectal artery, which was presumed to be the cause of the anal bleeding. Colonoscopic examination disclosed a submucosal tumor-like lesion in the left posterior wall of the rectum, 3 cm above the anal verge. After marking the boundaries by clipping, transanal resection of the lesion was performed. Histological examination revealed an irregularly expanded arteriovenous aggregation in the submucosal layer. The patient had a favorable postoperative course, and no residual AVM was seen on a postoperative selective inferior mesenteric arteriogram. There have been no signs of recurrence in the 2 gears since his operation.
