Embolization was bilateral in 71.4% of subjects, blood transfusion was required in 28.57%, incidence of complications was 53.57%, and seven of the embolized patients with intractable epistaxis suffered from recurrence of the epistaxis. There were no statistically significant differences between the embolized and unembolized groups. The mean hospital stay was longer in unembolized patients (4.46 days; SD = 2.42) than for the embolized patients (3.78 days; SD = 3.9), p=0.394. The most serious complications occurred in patients embolized with idiopathic epistaxis and the mean post-embolization hospital stay was longer in this subgroup (4.14 days; SD = 4.39) than in patients with Rendu-Osler-Weber syndrome (2.40 days; SD = 1.140), p=0.395. Unembolized patients with JNA presented greater hemorrhage (m = 2025 ml; SD = 325) and a longer mean hospital stay (m = 18 days; SD = 3) than the group of embolized patients (m = 360 ml; SD = 185 and m = 9 days; SD = 1, respectively).
