Overview
Dr. Raul Guzman is chief of the division of vascular surgery and endovascular therapy at Yale New Haven Hospital. He is also surgeon-in-chief, vascular surgery at the Heart and Vascular Center for the Yale New Haven Health System.
Dr. Guzman joins Yale Medicine from Beth Israel Deaconess Medical Center and Harvard Medical School. Prior to moving to Boston, he spent the early portion of his career at Vanderbilt Medical Center in Nashville, Tennessee, where he served for several years as chief of vascular surgery at the Nashville VA Hospital.
He received his medical degree from Johns Hopkins University in Baltimore, MD. After completing his residency in general surgery, he completed research training in the cardiology branch of the National Heart, Lung, and Blood Institute at the National Institutes of Health (NIH) and subsequently completed a fellowship in vascular surgery at Stanford University Hospital.
He recently completed his term as a permanent member of the Bioengineering, Technology, and Surgical Sciences Study Section of the NIH. His clinical interests relate to patients who have diabetic vascular disease, peripheral artery disease, and preventing amputation. His research focuses on the role of arterial calcification in lower extremity ischemia.
