Table 2: Comparison of embolization efficacy between patients with HHT and those with idiopathic epistaxis
HHT Idiopathic
Resolved after 1 embolization 3/12 (25%) 8/10 (80%)
Resolved after multiple embolizations 3/12 (25%) 1/10 (10%)
Rebleed requiring surgery 4/12 (33%) 1/10 (10%)
Significant continued bleeding despite surgery and embolization 2/12 (17%) 0/10 (0%)
Note:—HHT indicates hereditary hemorrhagic telangiectasia.
