Pseudoaneurysm of Tibioperoneal Trunk Postproximal Tibial Plating

Pseudoaneurysm is a false aneurysm which occurs at the site of arterial injury, and its walls are formed by surrounding tissue. We present a case of a 24-year-old male who presented with the complaints of swelling and pain over the back of the left leg, which was gradual in onset and progressive in nature, with a history of road traffic accident causing left proximal tibial fracture, for which left proximal tibial plating was done. On local examination, the patient had a swelling and tenderness; computed tomography angiography was performed, which showed rent in tibioperoneal trunk (TPT) with extravasation of contrast, which was suggestive of pseudoaneurysm of TPT. For this condition, left peripheral angioplasty was done under local anesthesia, and the patient was discharged the next day with postoperative medications.
