Successful covered stent-graft treatment of superficial femoral arterial injury due to blunt trauma.

BACKGROUND

Endovascular treatment is used for traumatic arterial injuries in the torso. However, the effectiveness of endovascular covered stent-graft treatment for peripheral artery injury is unclear. We present a case of superficial femoral artery (SFA) injury successfully treated with a covered stent-graft.

CASE REPORT: A 68-year-old man presented with traumatic lower limb injury and shock. Computed tomography angiography revealed left subtrochanteric fracture and hematoma with extravasation. Digital subtraction angiography revealed extravasation from a left SFA branch, and a pseudoaneurysm at the SFA trunk. We coil embolized the SFA branch, and treated the pseudoaneurysm with a covered stent-graft. Computed tomography carried out 22 days later showed complete pseudoaneurysm exclusion and sufficient stent patency.

CONCLUSION

We successfully used a covered stent-graft to treat SFA injury due to blunt trauma. A covered stent-graft could be effective for peripheral artery injury.
