[Embolization of the internal maxillary artery for severe epistaxis--including an experience of the approach from the superficial temporal artery].

Six cases of severe epistaxis were treated with the super-selective intraarterial embolization of the internal maxillary artery. Tens of fragments of Gelfoam were delivered into the distal internal maxillary artery and, additionally, embolized by several pieces of the coils. In a case with cerebral infraction, catheter was inserted via the superficial temporal artery. There were no complications due to these procedures in all cases of this study. It is considered that therapeutic intraarterial embolization of the internal maxillary artery is an effective therapy for severe epistaxis and the superficial temporal artery approach is useful for selected cases.
