Transcatheter arterial embolization as treatment for life-threatening maxillofacial injury.

A rare case of massive maxillofacial hemorrhage, which was controlled by transcatheter arterial embolization, is reported. A 23-year-old man with massive nasal and oral hemorrhage caused by maxillofacial fracture was admitted. Emergency angiography demonstrated extravasation of contrast material from the posterior superior alveolar artery, which was immediately embolized using gelatin sponge particles. This case shows that transcatheter arterial embolization is useful and effective for the treatment of massive hemorrhage resulting from severe maxillofacial injury.
