Introduction: A pseudoaneurysm is a pulsetile hematoma secondary to bleeding into soft tissue, which involves peripheral vessels in the most cases. A femoral artery pseudoaneurysm that is a rare complication, mainly occurs following prior arterial catheterization but it may also be formed with trauma. In this article a superficial femoral artery is reported. Case: The patient is a 24 years old woman who was admitted with a wound in the posteroinferior region of right tight 10 days before her recent referral. The skin of the wound had been repaired. After 1 week pain, progressing swelling in inferior region of tight and knee, fever, shivering and limping were presented. In physical examination, 90 degree flexion of knee, edema, warmth and tenderness in inferior region of tight were observed. Any pulse of dorsalis-pedis and posterior-tibialis was not touched. In the next step blood laboratory test, simple X-ray, Doppler sonography and magnetic resonance imaging (MRI) of right lower limb were accomplished. Finally, with the diagnosis of femoral artery pseudoaneurysm, excision of the pseudoaneurysm with reverse saphenous vein grafting was performed. Conclusion: Pseudoaneurysm should be noticed in patients with history of penetrating trauma and symptoms due to infection. In these cases sonography is necessary to get the exact diagnosis. The size of aneurysm and patient’s symptoms, determine the method of treatment.

Background: Peripheral nerve injures are common in clinical practice that includes from compression injury to complete disruption of nerve trunk. After injury nerves can grow and repair spontaneously, early end to end anastomosis is first choice for repair but only 50% of nerve fiber would be physiologically accurate and effective, thus several techniques for repair of nerve injury are introduced including combination of nerve transplant with silicon tubes, use of biologic and synthetic tubes for nerve conduit.

Materials and Methods: In this Exprimental study, 20 rats with the same weight were selected and kept in the same condition .The left sciatic nerve of them was cut and were divided in two groups.In the first group the facial flap method for repair of nerve injury was used .In the second group vein conduit method was used as standard method. Histological nerve repair was assessed after 45 days and the intact right sciatic nerve was used as control.

Results: Repair of nerve injury in proximal, mid and distal portion of nerve in facial flap method was more effective than vein conduit (P<0.05). Repair of nerve injury in proximal, mid and distal portion had no difference compared with control group (p>0.05).

Conclusion: Repair of nerve injury with facial flap method is more effective than standard method and can be used as a new method for nerve repair.
