简介：
Overview
This protocol presents a clinically relevant model of peripheral arterial disease using a combination of femoral artery and vein electrocoagulation along with a nitric oxide synthase inhibitor to induce hindlimb gangrene in FVB mice. The model allows for high-resolution imaging of the footpad vasculature through intracardiac DiI perfusion.
