Although the radial artery has proven to be a reliable conduit for arterial bypass procedures in cardiac surgery, its use in lower extremity revascularization has been limited due to its length. In patients who have undergone multiple cardiovascular procedures, venous conduit options can be limited, and infrapopliteal bypass with prosthesis has been shown to yield poor patency rates. In this report, the authors describe 3 different uses of the radial artery in patients with acute limb-threatening ischemia in the redo setting, which resulted in limb salvage.
