If you frequently have cold feet and toes, or pain in your legs, you should ask your doctor about peripheral artery disease (PAD). Many of the 8.5 million people in the U.S. who have PAD aren’t aware they have the problem, which is caused by fatty deposits in the arteries—most commonly the legs. As it progresses, PAD can narrow and harden arteries, restricting the flow of blood from the heart. PAD can potentially lead to such serious conditions as gangrene, loss of limb, and even death.

Yale Medicine vascular surgeons personalize their care for people with PAD by drawing from a toolbox of treatments that includes both traditional bypass surgeries and the latest minimally invasive endovascular approaches. These approaches use tiny instruments inserted into arteries and veins through small incisions.

“There has been an endovascular revolution that has transformed the treatment of these diseases completely,” says Cassius Iyad Ochoa Chaar, MD, a Yale Medicine vascular surgeon.
