Fig. 5
Top images show contrast angiograms performed at day 28 after FAO immediately prior to sacrifice showing the occluder (red arrow) and the anterior femoral artery immediately distal to the occluder (yellow arrow). The non-diabetic pig (left) shows good contrast opacification of the vessel immediately distal to the occluder while the diabetic pig (right) shows poor opacification. The green arrow identifies the profunda artery and blue arrow the circumflex branch of the anterior femoral artery that are providing more abundant collaterals in the non-diabetic pig than the diabetic pig. The bar graph below shows mean ± SD for ratios of contrast intensity between the distal anterior femoral artery and the profunda artery for the non-diabetic and diabetic pigs
