Hemorrhagic uterine necrosis after surgical vessel ligation and B-Lynch suture in persistent post-cesarean uterine atony: case report and review of literature
Keywords:Case report, CT, MRI, Hemorrhagic infarction, Uterine necrosis
Uterine necrosis is a rare life-threatening condition reported in few case reports and series, associated with uterine artery embolization for uterine fibroids or postpartum hemorrhage. We report a hemorrhagic uterine necrosis in a nulliparous 35 years-old woman underwent cesarean section at 40+1 weeks of gestation for obstructed labor, presenting post-partum persisting bleeding and uterine atony and congestion. Bleeding stopped only after placement of two set of compressive sutures, curettage of uterine cavity and placement of Bakri Balloon but the uterine body never contracted and become congested. Notwithstanding an effective antibiotic therapy, the patient developed an intermittent fever and signs of severe anemia. Clinical and radiological diagnosis with CT and MRI scan were compatible with uterine necrosis characterized by hemorrhagic infarction of the uterine wall and decomposition of its muscular tissue. Hysterectomy was discussed with patient and performed on day 32 after C-section. Uterine apoplexy, a rare life-threatening disease, was detected with CT by lack of uterine contrast enhancement and a gas-filled uterine cavity and necrosis was confirmed with MRI by showing fluid degeneration of the myometrium. Failure to recognize a necrotic uterus on imaging can cause delayed hysterectomy, which is mandatory and potentially life-saving.
