Ulcer-like projection is an angiographic sign of thrombosed aortic dissection. However, no pelvic manifestation of ulcer-like projection of aortic dissection has been reported. We report three patients in whom ulcer-like projections of the pelvic artery were revealed by rotational digital angiography using the newly developed computerized dynamic stereo-radiography apparatus.
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.
