Effective therapeutic strategy for massive retroperitoneal hematoma after conization: arterial embolization and pigtail catheter insertion

The loop electrosurgical excision procedure (LEEP) is commonly used to remove cervical intraepithelial neoplasia (CIN) because of its safety profile and likelihood of fewer complications. The authors report a rare case of massive retroperitoneal bleeding combined with hypovolemic shock after LEEP conization. Vessel injury was detected by angiographic computed tomography (CT) and embolization of the uterine artery was successfully performed to achieve hemostasis by an intervention radiologist. A pigtail catheter was subsequently inserted for the drainage of the large retroperitoneal hematoma. The patient did not show any further hemorrhage and recovered safely from hypovolemic shock. Th present case demonstrates a successful multidisciplinary and minimal invasive approach to manage retroperitoneal bleeding with uterine artery embolization. Thus, it should be considered a potential treatment option for hemostasis.
