Pelvic hematoma necessitans (PHN), a complication of massive hemorrhagic pelvic fracture, is reported in a 48-year-old pedestrian hit by an automobile. It was manifested by a tense hematoma of the buttocks and perineum that spontaneously "necessitated" or drained posterior to the anus 11 days after injury, resulting in complex anorectal morbidity and fecal contamination of a retroperitoneal hematoma and pelvic fracture sites. Early recognition, prompt diverting colostomy, and aggressive wound management are necessary after open pelvic fracture to prevent local and systemic infectious sequelae of PHN.
必需性盆腔血肿（PHN）是严重出血性骨盆骨折的一种并发症，本文报道了一名48岁被汽车撞到的行人出现该病症。其表现为臀部和会阴区出现张力性血肿，在受伤11天后血肿自发地“破溃”或经肛门后方引流，导致复杂的肛肠疾病以及腹膜后血肿和骨盆骨折部位出现粪便污染。开放性骨盆骨折后，早期识别、及时进行转流性结肠造口术以及积极的伤口处理对于预防PHN的局部和全身感染后遗症是必要的。
