Massive retroperitoneal hemorrhage secondary to femoral artery puncture: A case report and review of literature.

Rationale: A rare case of massive bleeding with rupture of the branch artery deriving from uterine artery was reported in the present study.

Patient Concerns: A 29-year old female patient received embolism of malformed cerebral vessels. Ten hours after the operation, a sudden drop in blood pressure occurred. The patient developed coma and shock, and again underwent interventional angiography, which revealed bleeding at the right femoral artery puncture site of the first interventional procedure. The bleeding sign disappeared by pressure dressing. At 19 hours after stable condition, blood pressure fell again, and it was considered that recurrent bleeding occurred at the femoral artery puncture point. Therefore surgical suture of punctured blood vessel was performed. Then the condition was stabilized again. After another 20 hours, the third times blood pressure dropped. The third interventional angiography displayed a rupture of the branch artery deriving from the right uterine artery. Blood pressure of the patient elevated after embolism of right uterine artery, and the condition gradually stabilized.

Diagnoses: The massive bleeding with rupture of the branch artery deriving from uterine artery seconded huge retroperitoneal hematoma after femoral artery puncture.

Interventions: The patient underwent three times interventional treatment including an embolism of malformed cerebral vessels, a right femoral artery interventional treatment, an embolism of the branch artery deriving from the right uterine artery and one time of surgical suture of punctured blood vessel.

Outcomes: Half a month of comprehensive treatment later, the patient was discharged from the hospital.

Lessons: Massive bleeding with rupture of branch of artery deriving from the uterine artery following grain retroperitoneal hemorrhage is extremely rare, to the best of our knowledge, it has not been previously reported. The rupture of branch of artery deriving from the uterine artery should be considered as one the differential diagnosis in the retroperitoneal hemorrhage when the bleeding cause was not found. Endovascular trans-arterial embolism was a safe, effective, and minimally invasive therapeutic option.
