Medial femoral circumflex artery pseudoaneurysm following intramedullary nailing for intertrochanteric fracture.

CASE

We present the case of a 92-year-old woman who developed a medial femoral circumflex artery (MFCA) pseudoaneurysm intraoperatively while obtaining reduction during intramedullary nailing (IMN) for intertrochanteric fracture.

CONCLUSIONS

Pseudoaneurysms are rare vascular complications in hip fracture surgery. Early recognition of signs and symptoms of this phenomenon are essential for diagnosis and treatment. Close post-operative monitoring and serial hemoglobin should be considered for unexplained intra-operative bleeding. A low threshold for angiography should be entertained if active bleeding and clinical decompensation occur during instrumented percutaneous pertrochanteric fracture reduction. This patient underwent conventional angiography with successful coil embolization and exclusion of the MFCA pseudoaneurysm.
