Distal Femoral Arteriovenous Fistula with Iliac Vein Thrombosis after Blunt Trauma

ABSTRACT

A 39-year-old woman arrived at our emergency department, complaining of severe pain and swelling of her left leg. She had slipped down stairs and injured on her left leg about 3 months ago. Computed tomography angiography showed left distal superficial femoral artery’s pseudoaneurysm with arteriovenous fistula and thrombotic occlusion of left common iliac vein. We decided to do endovascular intervention due to severe venous hypertension and chronic inflammation around the fistula. The femoral arteriovenous fistula was closed via stent-graft (7 mm×5, 9 mm×5 cm) deployment. The occluded left iliac vein was reopened by nitinol metal stenting (12 mm×4 cm, 14 mm×4 cm). The authors report a very rare case of femoral arteriovenous fistula combined with iliac vein thrombosis developed after a blunt trauma.
