(A) Computed tomographic angiography showed a massive hematoma near the branch of lateral circumflex femoral artery irritated by the sharp inferior margin of the lesser trochanter that was displaced superior and anterior (arrowheads). (B) Percutaneous transcatheter angiogram showed cutting of the ascending branch of the lateral circumflex femoral artery because of the sharp inferior margin of the displaced lesser trochanter (arrowhead). (C) After superselection of the bleeding artery using a microcatheter and guidewire, embolization of the bleeding artery was done using micro-coil (3.2 mm, 1×; 4.2 mm, 1×) (arrowhead). No extravasation of the left deep femoral artery was observed in the post-embolization angiogram. (D) Surgical evacuation of the hematoma near the vastus lateralis and intermedius was done under spinal anesthesia.
