Abstract
Background: RenduOslerWeber disease (Hereditary Hemorrhagic Telangiectasia; HHT) is a cause of refractory epistaxis. Several treatments have been established for HHT epistaxis, but there are few reports about the use of superselective embolization for its treatment. We report a case of frequent epistaxis because of HHT in a patient whose condition was treated by superselective embolization with nbutyl 2cyanoacrylate (NBCA) using a triple coaxial system.
Case report: A 51yearold male, who had HHT, has been suffering from epistaxis in spite of several treatments by otorhinolaryngologist. The site of bleeding was visualized by angiography, and the superselective catheterization was applied to the branch of the sphenopalatine artery just proximal to the lesion. Complete embolization was achieved successfully with NBCA.
Discussion: Endovascular treatment appears to be effective for refractory HHT epistaxis. Superselective embolization may be essential so as to secure the access route to the lesion for repeated treatments because the epistaxis from HTT recurs frequently.
Conclusion: Superselective embolization may be a new option for HTT epistaxis.
