Disseminated intravascular coagulation (DIC) in obstetrics is related to postpartum hemorrhage and has been a leading cause of maternal death. We here report a successful treatment, via damage control surgery (DCS), of a life-threatening massive hemorrhage of more than 20,000 mL due to DIC. A 30-year-old female was admitted to our hospital because of atonic bleeding. Since she was having a uterine rupture, an emergency hysterectomy was performed. Because of the severe DIC (fibrinogen, 65 mg/dL; platelet count, 6.0 × 109/L), oozing persisted after the hysterectomy; thus, intraperitoneal gauze packing was performed as DCS. Afterwards, the coagulopathy was corrected, and the gauze was removed on the second postoperative day (POD 2). The patient was discharged without complications on POD 16. The present case demonstrated that performing DCS and waiting for improvement of the coagulation system can be one of the treatment options for management of patients with severe DIC.
