Maxillary and ethmoidal artery ligation is generally effective for treating severe epistaxis. However, we have occasionally experienced continuous or recurrent bleeding after this procedure. We encountered a 81-year old male with severe epistaxis occuring 5 years after ligation of the internal maxillary artery and anterior ethmoidal artery. Nasal packing was not effective and angiography was performed by Seldinger's method in order to confirm the site of bleeding. As a result, the reconstruction of flow to the internal maxillary artery through a collateral was found, and embolization was performed with a gelatin sponge. No further epistaxis or side effects from the embolization occurred. Therapeutic intraarterial embolization is useful for controlling severe epistaxis such as that caused by failed ligation.
