Hirota\u2019s Grade 1 patients were assigned to G1 group and underwent treatment with 5% EOI. Grade \u2265 2 patients prior to August 2015 were G \u2265 2 group treated with 5% EOI, and those treated thereafter were GERTO group. The amount of EOI used per unit GV volume (EOI\/GV ratio), the times to embolization and recurrence rate of GV were evaluated.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results:<\/jats:title>\n                  <jats:p>The EOI\/GV ratio was 0.66 \u00b1 0.19 in G1, 1.5 \u00b1 0.8 in G \u2265 2, and 0.58 \u00b1 0.23 in GERTO (G \u2265 2\u2009vs GERTO, p &amp;lt; 0.0001).
