Description

<p>A Japanese woman in her 80s fell down the stairs in her home and was immediately transported to a hospital. She was diagnosed as having traumatic pelvic ring fracture. She was hypotensive and therefore transferred to our hospital for further treatment. On admission, she was found to be in severe hemorrhagic shock. Then we performed emergent transcatheter arterial embolization (TAE) for the bilateral internal iliac arteries, followed by external skeletal fixation of the pelvic ring. On day 2, her hemoglobin level decreased and contrast-enhanced CT showed a contrast blush in front of the injured sacrum. Emergent angiography showed massive bleeding from the medial sacral artery, for which we performed TAE with metallic coils. Her clinical course after the TAE was uneventful. The median sacral artery is one of the pelvic arterial branches but is rarely injured by pelvic fracture. We herein report a case successfully treated with TAE.</p>
