Pathological Subtrochanteric Femoral Fracture Due to Extensive Arterio-venous Malformation. A Case Study.

Despite the case of a 19-year-old male with a pathological subtrochanteric left femoral fracture in the course of an extensive arteriovenous malformation of the left thigh. The arteriovenous malformation was diagnosed when the patient was 16 years old. He has undergone several embolization procedures. The fracture was caused by a fall from the patient's own height. Before the patient was qualified for surgery of the fracture, a left lower limb angiography confirmed the presence of extensive pathological vascularity (arteriovenous malformation), and an embolization procedure was performed on the branches and trunk of the left deep femoral artery, several vessels branching off of the proximal and distal segment of the superficial femoral artery and one branch of the internal iliac artery. That was followed by internal stabilization of the left femur with a Targon PF intramedullary nail, resulting in an optimal therapeutic effect with a relatively low blood loss. This case presents a rare clinical problem that constitutes a significant therapeutic challenge.
