Angiogram of a patient before a Fontan procedure demonstrating a significant systemic-to-pulmonary collateral. (A) Contrast injection into the right internal mammary artery showing a large tortuous artery. (B) Levophase of the same injection demonstrating opacification of the pulmonary vein. (C) Repeat contrast injection into the left internal mammary artery after coil occlusion with multiple Gianturco coils showing no evidence of residual collaterals.

Comparison of the 72 operative survivors who did not have occlusion of systemic-to-pulmonary collaterals postoperatively with the 18 patients who had postoperative coil occlusion. Error bars represent 95% confidence limits. Vent = duration of ventilation; inotrope = duration of inotropic support; ICU = intensive care unit stay; hosp = duration of postoperative hospitalization.
