Postpartum hemorrhage is one of the most frequent complications in obstetrics, being the second cause of maternal mortality worldwide. Uterine atony is its main cause. Once the hemorrhage is established, the time and management of it will depend on the expertise of the obstetrician. Initially, treatment focuses on the use of uterotonic drugs, but in the absence of an adequate response, conservative surgical management may be chosen. Compressive uterine sutures are considered a good treatment option. An effective and simple surgical technique is described by Hayman, a valuable tool for the control of postpartum hemorrhage. We present the case of a 17-year-old patient, 37 weeks pregnant and diagnosed with severe preeclampsia, who presents placental abruption and posterior uterine atony, who underwent uterine compressive suture by Hayman technique, with satisfactory evolution.
