  • Associate Professor Term

    Edouard Aboian, MD, is a vascular surgeon who specializes in aortic and limb preservation procedures, offering endovascular and open surgical solutions—sometimes a combination of the two—as well as medical therapies depending on the patient’s needs. “I try to work not just with the patient, but with the entire family to put them at ease in what can be a difficult situation,” he says. “In many cases, I want them to understand that they have something that is treatable. We deal with these things every day, and we often can improve or completely reverse the problem that they have. It can be fixed.” In many cases, treatment for aneurysms and other vascular problems has become easier with minimally invasive endovascular approaches, which involve working through small incisions in the groin or sometimes the arm, Dr. Aboian says. “Inside the body there is big work done, but outside, you only see...
