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
