Pertrochanteric fractures count among the most frequent fractures in elderly persons but their vascular complications are rare. We present two cases of pseudoaneurysm following internal fixation for pertrochanteric fractures in relatively young patients aged 67 and 68-years-old. The post-operative follow up was marked by the onset of a pulsatile swelling in the inner thigh. The diagnosis of pseudoaneurysm of the deep femoral artery was made by arterio-venous Doppler-ultrasound and CT-angiography. The pseudoaneurysms were managed by open surgery for the first case and by a stent for the other one. Both of them got a good outcome.
