Embolization in the treatment of epistaxis after failure of internal maxillary artery ligation.
Internal maxillary artery ligation is effective in treating epistaxis. Occasionally a patient may continue to hemorrhage after this procedure. Evaluation of postoperative angiograms reveals several factors accounting for the failure of internal maxillary artery ligation. These factors include incomplete ligation of vessels, alternative dominance of vessels, and reconstitution of flow through collaterals. Eleven such patients have been successfully treated with angiography and embolization. There was one complication of skin slough in the region of the columella. Embolization is a useful modality in the management of these difficult cases.
