Why Yale Medicine?
  • We specialize in traditional and minimally invasive surgeries, and sometimes combine the two to treat the most complex cases.
  • When open surgeries are required, we use advanced techniques to reduce discomfort after surgery, recovery time and scarring.
  • As researchers, our doctors have with access to the latest knowledge, which means patients benefit from the most advanced care available.

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 and assistant professor of surgery at Yale School of Medicine.  

Clinical Trials

New treatments for many conditions are tested in clinical trials, which ultimately bring lifesaving new drugs and devices to the patients who need them most. By participating in a clinical trial, you may get access to the most advanced treatments for your condition, and help determine their benefits for future patients.
