Reconstruction of sacral defects following necrosis of buttocks due to embolization of internal iliac artery using a transverse lumbar flap.

Fractures of the pelvis associated with uncontrollable hypotension are managed by stabilization of fractures and arteriographic embolization of the bleeding vessels. Embolization of these arteries may result in necrosis of the buttocks. The use of a transverse lumbar artery-based flap can be used for repair of these defects.
