 Final angiogram with a contrast injection in the left superior vena cava showed a forward flow through the right Glenn, a good contrast filling of the right lower pulmonary artery, and a widely patent left Glenn negative contrast washout of the proximal right pulmonary artery and left pulmonary artery presumably due to aortopulmonary collateral flow.
