Bilateral bidirectional Glenn without cardiopulmonary
bypass
This procedure was again used in the setting of tricuspid atresia. Since
the superior caval vein was very short, and the retroaortic left
brachiocephalic vein was located behind the ascending aorta, the
superior caval vein was cannulated into the right brachiocephalic vein.
Because of the retroaortic location, both the caval veins required
extensive mobilization. A bilateral bidirectional Glenn was performed
using a temporary stent between the superior caval vein and the right
atrium.48
