Abstract：
Pseudoaneurysms of the middle rectal artery are rare. When encountered, these have the potential for significant morbidity and mortality due to bleeding and potential rupture. Endovascular embolization is a feasible option in the management of these pseudoaneurysms. The present report describes a case of a 43-year-old male presenting with hemorrhagic shock secondary to lower gastrointestinal bleeding one day after undergoing excision of an external perineal condyloma, incision and drainage of a perirectal abscess, and biopsy of a perianal mass. Angiographic imaging revealed a right middle rectal artery pseudoaneurysm. Selective embolization of the right middle rectal artery and bilateral superior rectal arteries was successfully performed. At the two-week post-embolization follow-up, hemoglobin was stable, and the patient reported normal bowel movements with no episodes of bleeding per rectum.

直肠中动脉的假性动脉瘤很少见。遇到时,由于出血和潜在的破裂,这些有可能导致显著的发病率和死亡率.血管内栓塞是治疗这些假性动脉瘤的可行选择。本报告描述了一例43岁的男性，在接受会阴外尖锐湿疣切除后一天，出现继发于下消化道出血的失血性休克，直肠周围脓肿的切开和引流，和肛周肿块的活检。血管造影显示右直肠中动脉假性动脉瘤。成功进行了右直肠中动脉和双侧直肠上动脉的选择性栓塞。在栓塞后两周的随访中，血红蛋白稳定,患者报告肠蠕动正常，每个直肠没有出血事件。
