Emergency management of profunda femoris artery rupture caused by subtrochanteric femoral fracture: A rare case report.

RATIONALE: In clinical practice, subtrochanteric femur fractures are common. However, fractures accompanied by profunda femoris artery injury are relatively rare.

PATIENT CONCERNS: In our study, we report a case of a 50-year-old male admitted with a primary diagnosis of a right subtrochanteric femur fracture with rupture of the profunda femoris artery. The patient was admitted following a fall from a height.

DIAGNOSES: Upon admission, X-ray showed a right subtrochanteric femur fracture, but physical examination revealed abnormal blood flow in the right groin area. A color Doppler ultrasound confirmed a rupture of the right profunda femoris artery.

INTERVENTIONS: During preparation for emergency surgery, the patient's blood test results indicated severe anemia. We coordinated with the blood bank to provide a substantial blood supply to the patient, and successfully anastomosed the profunda femoris artery during surgery.

OUTCOMES: Once vascular stability was achieved, we proceeded with intramedullary nailing fixation for the right subtrochanteric femur fracture, resulting in good fracture healing.

LESSONS: This newly identified injury pattern, subtrochanteric femur fracture with profunda femoris artery rupture, has not been previously reported in the literature. Further research is needed to explore the mechanism of this injury pattern, and it should be given due attention in clinical practice.
