Our division's active research program includes extensive clinical research focused on patient outcomes and new technologies, as well as NIH-funded basic science research.

Clinical Research

The Division of Vascular and Endovascular Surgery conducts a very active clinical research program, including:

  • Outcome studies of arterial reconstructive surgery, including the ultimate well-being and independence of patients, prevention of amputation and stroke, the risks and benefits of all procedures.
  • Wound healing agents and technology, especially for problems related to the foot in diabetes.
  • Studies of the microcirculation as affected by diabetes, menopause, estrogen and estrogen replacement theory.
  • Studies of endovascular technology, such as stent grafts and the use of angioscopy during surgical procedures.

Basic Research

The basic science research program has been funded by the NIH for more than 20 years, including programs such as:

  • Determining the mechanisms that lead to failure of some bypass grafts. This work has led to the identification of genes that play an important role in the response of arteries to an injury.
  • Improving the methods used to prepare and handle vein grafts in the operating room.
  • Development of surfaces that are resistant to infection.
  • Identification of blood flow disturbances leading to atherosclerosis and failure of arterial bypass grafts.

Mauricio Contreras, MD 
Research Focus: Developing novel biomaterial surfaces

Christiane Ferran, MD, PhD 
Research Focus: Role of A20 in organ transplantation, diabetes, atherosclerosis, and hepatitis

Raul Guzman, MD 
Research Focus: The role of arterial calcification in lower extremity vascular disease. We are interested in the mechanisms by which smooth muscle cells in the arterial wall become phenotypically transformed into bone-like cells
