Conservative management of giant retroperitoneal hematoma after cesarean section in severe preeclampsia: a rare case report.

Background: Spontaneous retroperitoneal hematoma (RPH) after cesarean section is an extremely rare disease with various causes, which can lead to unexplained maternal shock and death. Because cases of RPH are extremely rare in obstetric settings, there is also a paucity of literature.

Case presentation: This study reports a rare case of giant RPH after cesarean section. The patient underwent cesarean section due to severe preeclampsia at 38 weeks of gestation. The procedure was uneventful with little intraoperative bleeding, but a huge retroperitoneal hematoma developed 18 h after the operation and was successfully managed conservatively.

Conclusions: The treatment taste of retroperitoneal hematoma depends on the size of the hematoma, the etiology, and the hemodynamic status of the patient. For patients in stable condition, conservative treatment can be adopted, such as fluid infusion, blood transfusion, vascular embolization and hematoma drainage.
