A simple technique of distal limb perfusion during prolonged femoro-femoral cannulation

Objective: Cannulation of the femoral vessels for cardiopulmonary support is a common approach for many cardiac procedures as well as access of choice for many emergency bypass systems such as extracorporeal membrane oxygenation. A serious complication of prolonged femoral cannulation remains the ischemic injury of the distal limb. Subjects: To minimize the incidence of ischemia in the cannulated leg, we have begun to provide antegrade femoral blood flow by placing a vascular introducer percutaneously distal to the arterial cannula into the superficial femoral artery and connecting it to the side port of the arterial line. Conclusion: This technique of distal limb perfusion was found to be safe and effective in preventing lower limb ischemia for patients with prolonged femoral cannulation for extracorporeal circulatory support.
