There are numerous opportunities for the Fellow to participate in clinical and basic-science research. The Division of Vascular Surgery participates in several landmark clinical research trials supported by industry and the National Institutes of Health. These projects focus on aortic and acute limb pathologies and investigate emerging device technologies and vascular/endovascular techniques.

Our Division participates in the SVS-PSO Vascular Quality Initiative (VQI), a national registry of vascular surgical outcomedata used for both quality and vascular surgical outcomes. Tracked procedures include carotid endarterectomy and stent placement, infra-inguinal bypass and peripheral vascular interventions, and open and endovascular aortic repairs, along with thoracic aortic/ complex endovascular aneurysm repairs.

The Vascular Surgery faculty also participates in the Surgical Outcomes and Applied Research initiative (SOAR), a collaboration between the Department of Surgery and the Adult and Child Center for Health Outcomes Research and Delivery Science (ACCORDS).

Vascular Surgery utilizes the research services of the Colorado Prevention Center (CPC), an academically led clinical research organization which has responded to the demands of a fast-paced clinical research industry and competitive market for over two decades. The CPC offers full-service clinical trial design, oversight, and management with rapid access to key opinion leadersin a variety of therapeutic areas. These individuals are on the cutting edge of scientific, clinical and regulatory developments. Many of CPC's leadership team have chaired and/or served on FDA advisory committees.

The Division of Vascular Surgery also devotes its research efforts to clinical and outcomes research through multidisciplinary collaborations with the Departments of Cardiology, Cardiovascular Surgery, Vascular Medicine, Interventional Radiology, and Bioengineering. There are numerous opportunities for the vascular surgery fellow and surgical residents to participate in research. With all of the medical sciences concentrated on the Anschutz Medical Campus, collaboration between scientists and physicians is nearly effortless.
