Figure 5 Effect of Venous Collaterals on Z-Scores for Weight Over Time

Growth was impaired in patients with >2 collaterals in the pre-Fontan (p < 0.01) and in the post-Fontan (p = 0.01) period. No difference was seen between patients after embolization of collaterals and those who had <2 active collaterals (p = 0.89 pre-Fontan; p = 0.19 post-Fontan).
