37 patients with intractable idiopathic epistaxis were treated with superselective embolisation between 1995 and 1999. A total of 40 embolisations was performed, including three procedures for recurrence. The embolic material was gelatin sponge in 27 procedures, microcoils in 9 and both gelatin sponge and microcoils in 4. Immediate cessation of nasal bleeding was obtained in all patients after embolisation. Recurrent epistaxis occurred in 2 (5.4%) of the 37 patients within 7 days after initial embolisation, giving a short-term success rate of 94.6%. The long-term follow-up ranged from 1-51 months (mean 21.6 months). Late re-bleeding occurred in two patients, giving a long-term success rate of 94.6%. Two patients underwent re-embolisation; it was necessary to embolise the ipsilateral facial artery and/or the contralateral internal maxillary as well as the ipsilateral maxillary artery. Although the overall complication rate was 45.0%, no major complications occurred. Superselective embolisation with gelatin sponge is an effective and safe treatment technique for intractable idiopathic epistaxis.
