Fig 2 Illustration of the preferred site for extrathoracic cannulation for extracorporeal membrane oxygenation. The Annals of Thoracic Surgery 2001 71, 1421-1427DOI: (10.1016/S0003-4975(00)02504-2) Copyright © 2001 The Society of Thoracic Surgeons Terms and Conditions
Fig 3 Diagram illustrating the appearance and position of the arterial cannula used for the return limb of the extracorporeal membrane oxygenation (ECMO) circuit.

Fig 4 Illustration of one of the techniques used to ensure maintenance of blood flow to the distal lower limb during femoral cannulation. The side cannula entering the femoral vessel distal to the cannulation site ensures flows greater than 150 mL/min. (ECMO = extracorporeal membrane oxygenation.)

Fig 5 Illustration of the T-graft approach to maintaining both central arterial blood flow and distal lower limb perfusion. A polyethylene terephthalate graft is attached to the femoral artery, and the cannula is inserted into and tied to the graft. (ECMO = extracorporeal membrane oxygenation.)
