Objectives: Treatment of severe epistaxis can encompass many modalities. Control rates with all treatments are good. Morbidity among treatment groups varies. Angiographic embolization is one such method that has a very low complication rate. Over the last 10 years, it has become the preferred treatment at our institution.
Study design: Tertiary medical referral centers: OHSU, Portland VAMC.
Materials and methods: Retrospective review of 70 patients transferred or admitted with posterior epistaxis and treated with selective angiographic embolization from 1993 to 2002.
Results: Patients had bleeding for a median of 4.5 days prior to admission. 79% were unilateral. Etiology of bleeding was: idiopathic (61%), previous surgery (11%), anticoagulants (9%), trauma (7%), and other causes (12%). 30% required blood transfusions prior to admission to OHSU (average 4.4 units). No patient required a transfusion postoperatively following angiographic embolization or during their hospitalization. The internal maxillary artery (IMAX) was embolized in 94% (47% unilateral or bilateral IMAX only, 47% unilateral or bilateral IMAX in combination with other vessels, 6% other vessels besides the IMAX). Mean length of stay was 2.5 days. 86% had minor or no complications after the embolization and were discharged within 24 hours. 13% had a major rebleed that required surgical intervention within 6 weeks of the embolization. One patient had a serious neurological complication. Using the data available on 68 of 70 patients, the cost of hospitalization averaged dollar 18,000 with direct costs of embolization averaging dollar 11,000.
Conclusions: Angiographic embolization is a clinically effective treatment for severe epistaxis.
