摘要
a 16-year-old male patient sustained pelvic blunt trauma followed by an abscess formation of the psoas muscle and other infectious complications. open drainage of the retroperitoneal abscess resulted in massive hemorrhage that was temporarily controlled by packing. after endovascular treatment by embolization of branches of the hypogastric artery, the hemorrhage was definitively controlled. packs were removed and the patient was discharged with no further complications.
