Aortic cannulation
An arterial cannula is usually inserted into the ascending aorta. Alternate sites include the femoral, innominate or axillary artery in situations such as emergency, redo surgery, minimally invasive surgery or to achieve regional perfusion in procedures that involve the ascending aorta and arch.
Aortic cannulas come in a variety of commercially available options. Cannula size should be selected in conjunction with the perfusionist team so as to utilize the appropriate cannula for adequate flow within the circuit.
