B-Lynch compression suturing was performed on a 30-year old primipara during emergency Cesarean section (CS). After CS, she developed a low-grade fever, a subinvolution and tenderness of the uterus, and a pronounced increase in the inflammatory markers. Antibiotics were altered according to bacterial cultures and drug sensitivity testing of the cervix. By 10 days postpartum, a diagnostic curettage was performed and released a foul-smelling liquid matter due to the substantial amount of heterogeneous material with gaseous echoes showed via ultrasonography. The inflammatory markers gradually returned to normal by 9 days post curettage. At 12-day post curettage, a foul-smelling purulent tissue was extruded spontaneously via the vagina and proved to be necrotic tissue on pathologic examination. Eighteen months after childbirth, the patient had not experienced a menstrual period or subsequent pregnancy and a small uterus without any evidence of an endometrium showed by ultrasonography.
