Post-Glenn Shunt Systemic Desaturation—Is Venovenous Collateral the Culprit?
After classic Glenn shunt or bidirectional cavopulmonary anastomosis, the reappearance or deepening of cyanosis may be due to systemic venous collateral channels. There are only few case reports on this issue in the present literature. Here, we present two cases that underwent bidirectional Glenn shunt, who later presented with cyanosis and desaturation and both of them were found to have venovenous collaterals.
