Department of Surgery

Edith Tzeng, MD

  • Professor of Surgery
  • Chief of Vascular Surgery, VA Pittsburgh Healthcare System, University Drive

Dr. Tzeng’s research focuses on vascular related topics. She has a strong focus on translational studies of vascular healing and wound healing. The effect of small molecules such as carbon monoxide and nitric oxide on the prevention of intimal hyperplasia is an active area of research with an attempt to understand the mechanisms by which these molecules achieve their benefit in the vasculature. Related to vascular healing is cutaneous wound healing. The beneficial effects of CO and NO have also been shown in cutaneous wound healing and efforts are ongoing to better evaluate these effects. The ultimate goal of her research is to bring these agents to clinical application.
