Abstract
Aneurysms of the superior gluteal artery following blunt trauma are relatively rare. A 38-year-old man was injured in a traffic accident. On day 8 of hospitalization, invasive open reduction and internal fixation was performed for an unstable pelvic ring fracture. Postoperative wound infection occurred, and wound cleaning was performed on a daily basis. On day 41 of hospitalization, he began experiencing sudden buttock pain, and image diagnosis revealed a superior gluteal artery pseudoaneurysm. On day 44, transcatheter arterial embolization was performed, his symptoms were resolved, and no obstruction was observed. Distinguishing traumatic and infectious aneurysms is extremely difficult. Embolotherapy for pseudoaneurysms is an effective treatment procedure.
