ABSTRACT
Spontaneous rupture of the ovarian artery is very rare and can cause retroperitoneal hemorrhage, which is seriously life-threatening. Herein, we reported a case of massive retroperitoneal hematoma caused by spontaneous rupture of the right ovarian artery during pregnancy and intrauterine fetal death. A 32-year-old woman, gravida 6 para 5, had non-specific right lower abdomen and low back pain in the third trimester. Emergency cesarean section was performed due to the increased pain and decreased fetal heart rate. A huge retroperitoneal hematoma and intrauterine fetal death were found. Then, the abdomen was closed due to unknown source of bleeding and unstable vital signs. Computed tomography scan was conducted to clarify the extent of the retroperitoneal hematoma. Digital subtraction angiography confirmed the rupture of the right ovarian artery. A transcatheter artery embolization was successfully performed to control the bleeding. The patient ultimately recovered well after surgery.
