Cassius Iyad Ochoa Chaar, MD, MS, is a vascular surgeon who treats a range of problems affecting the circulatory system. He has special expertise in treating peripheral artery disease, which can block blood flow in the arteries in the arms and legs. He is an expert in lower extremity limb preservation, particularly in diabetic patients.
“The most exciting breakthrough in vascular surgery has been the evolution of minimally invasive surgery that has transformed the specialty completely,” Dr. Chaar says. The vast majority of his patients now have minimally invasive endovascular surgeries, which involve accessing a damaged artery by making a puncture and inserting a wire and a catheter. But he still performs traditional open surgeries—with long incisions that allow him to view and treat problems directly. He sometimes uses a combination of approaches to treat complex cases.
An assistant professor of vascular surgery at Yale School of Medicine, Dr. Chaar says he was motivated to go into medicine when he was growing up and saw the positive impact a doctor had on his grandmother, who had complicated medical problems. “I wanted to be that person who touched peoples’ lives and made them better,” he says.
Dr. Chaar speaks Arabic, English, French and Spanish.
