Left Brachiocephalic Vein Cannulation in Bicaval Venous Drainage Is Safe, Effective, and Technically Advantageous.

Direct cannulation of both venae cavae (bicaval venous cannulation) is the gold standard for right atrial isolation in intracavitary surgery, but there has been no consensus about an alternative site. Therefore, we studied an alternative method for bicaval venous drainage in which the left brachiocephalic vein (LBCV) is cannulated instead of the superior vena cava. From 2012 through 2014, we performed routine LBCV cannulation in 150 consecutive patients as part of bicaval venous drainage before right atrial isolation.
