Understanding P.A.D
Constantino Pena, Interventional Radiologist at Miami Cardiac and Vascular Institute, explains an artery has different layers and there are the blood cells running through the artery and the platelets, but the plaque or atherosclerosis can narrow the artery so you start getting less
blood flow down to the leg, for example.
"Over time it can get to a critical point where you may not be getting enough blood to the extremity," he says.
