Mitigating limb ischemia in veno-arterial extracorporeal membrane oxygenation: A narrative review of evolving role of distal perfusion catheters

Figure 1 Image showing the distal perfusion catheter in the left lower extremity. A: Shows distal perfusion catheter (green arrow), extension tubing with stop cock (orange arrow), venous cannula (blue arrow) and arterial cannula (yellow arrow); B: Close up view focussing on the distal perfusion catheter (green arrow) also showing connection with arterial cannula via a side port (black arrow), an intervening 3-way stop cock for regular flow check (white arrow) and a 6-inch extension tubing (orange arrow); C: Additional view showing distal perfusion catheter (orange arrow), venous cannula (blue arrow) and arterial cannula (yellow arrow).
