Established in 1985, the Vanderbilt Vascular Laboratory was the first ever to provide a cohesive vascular diagnostic center at Vanderbilt University Medical Center. Hence, the dominant source for inpatient and outpatient vascular testing with ultrasound is accomplished at the Vanderbilt Vascular Laboratory. Accreditation by the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL) is established for cerebrovascular testing as well as venous testing.

The Vanderbilt Vascular Laboratory performs 4,000 vascular studies annually and is supported by four full-time and part-time RVTs. In addition, the Vascular Laboratory supports intraoperative studies and has been a basis for a substantial amount of ultrasound-directed procedures, most notably the placement of inferior vena cava filters at the bedside. During the fellowship, the trainee acquires experience with non-invasive modalities, as well as the ability to provide interpretation and the skills needed to establish or direct a vascular laboratory.

Ongoing research emphasizes endovascular grafting for aortic aneurysms and peripheral vascular disease. Endovascular grafting was initiated in 1993 and has rapidly expanded. Additional endovascular grafting projects are underway in this exciting new area in the specialty of Vascular Surgery.

Basic Science Research

Basic science research on enhancement of the patency of vascular bypass grafts has led to the identification of a protein that is felt to be involved with relaxation of smooth muscle associated with vascular bypass grafts and other smooth muscle tissue. These efforts, directed by Dr. Brophy, are funded through NIH and the Veterans Affairs and are being expanded through bioengineering collaborative efforts to develop therapeutic agents in the treatment of fibrosis, inflammatory disorders, and epithelial cancers.
