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.
卵巢动脉自发性破裂十分罕见，可导致腹膜后出血，严重时会危及生命。1例妊娠期右卵巢动脉自发性破裂致腹膜后巨大血肿且胎死宫内的产妇，32岁，妊娠6次，分娩5次，妊娠晚期出现非特异的右下腹及腰背部疼痛。因疼痛加剧、胎心下降而于急诊剖宫产，术中发现腹膜后巨大血肿、胎死宫内。因出血来源不明、生命体征不平稳予以关腹。计算机断层扫描显示有腹膜后血肿，数字减影血管造影证实右卵巢动脉破裂，予以经导管动脉栓塞后成功止血。患者术后恢复良好。.
