Program Description

Interested in the Vascular Surgery Integrated Residency at USC/LA General Medical Center? Hear from our Vascular Surgery Integrated Residency program director about what makes our program unique.

  • The Division of Vascular Surgery and Endovascular Therapy was established in 1995 with two dedicated vascular surgery faculty. The Division has grown to include twelve faculty who provide vascular and podiatric surgical services at six hospitals in the greater Los Angeles area. Embedded in the Division are two beacon programs: USC Comprehensive Aortic Center and the USC Limb Preservation Center which is part of the Southwestern Academic Limb Salvage Alliance (SALSA).

    The USC Comprehensive Aortic Center oversees the regional aortic transfer program which brings close to 300 patients per year to Keck Medical Center with acute aortic syndromes including type A and B dissections and ruptured aortic aneurysms. Complementing this large aortic experience, is a clinical research program which includes an Investigational Device Exemption (IDE) program for branch and fenestrated endograft treatment of aortic aneurysms and dissections, participation in numerous aortic device trials and collaborative research with the Viterbi School of Engineering.

    The objective of the USC Limb Preservation Center/SALSA is to eliminate preventable amputation in people with diabetes. The program is a collaborative clinical and research alliance that is dedicated to advancing care of the diabetic foot and preventing lower extremity amputations. The Center brings more than 1000 patients per year to our clinics from the Los Angeles region and around the world. Division faculty who are part of the Center are leaders in the American Limb Preservation Society (ALPS) and the Society for Vascular Surgery. DFCon, the largest annual meeting in the world dedicated to limb preservation is co-sponsored and organized by Center/Division faculty.

    The above beacon programs, the excellent vascular and podiatric surgical faculty and the strong collection of unique hospital experiences, provide the resident/fellow with an outstanding clinical experience in vascular surgery. The independent USC program in vascular surgery was accredited by the Residency Review Committee in Surgery on July 1, 2000. The integrated program was granted approval in October 2010. Both programs are fully accredited and conducted through the Department of Surgery at the Keck School of Medicine of USC.

  • Our program offers a robust educational curriculum. Integrated residents are initially fully immersed in the comprehensive general surgery curriculum when rotating on their core general surgery rotations. Residents during the first three years participate in the general surgery surgical simulation program, which includes protected time every week for simulation training. This simulation curriculum is differentiated by year of training and includes a PGY1 intern boot camp and progressive PGY2 and PGY3 procedural based training.

    Once residents have progressed to senior status (PGY4, PGY5) and joined with the independent vascular surgery fellows the educational curriculum is focused on vascular surgery and disease. This includes weekly teaching conferences giving the residents the opportunity to go through the critical thinking necessary to adequately prepare for complex vascular cases. In addition, there are regularly scheduled journal clubs and weekly interactive didactics that mirror the major vascular textbooks. Residents also have monthly sessions in our simulation center which includes unrestricted fresh tissue dissection that gives the opportunity for preparation for open vascular exposures and procedures.

  • The USC vascular division is involved with every major ongoing clinical trial of advanced aortic endovascular devices.  We are currently a leading enroller in the WL Gore TAMBE trial and Thoracic Branched Endograft trial, as well as being a pilot site for the ARISE (ascending aortic stent graft), and the Terumo Relay Branch (dual arch branch) trial.  We were the nation’s leading enroller for the recently completed BEST-CLI trial.

    In additional to national trials our division is a prolific contributor of outcomes-based research and innovative technique papers.  Some of the particular areas of research interest of faculty members include limb salvage, advanced endovascular aortic repair, aortic dissection, vascular trauma, treatment of mycotic aneurysms, TCAR, complex hemodialysis access management, and angiosome-based lower extremity revascularization.

    Our division has been awarded numerous research grants including a recent R01 grant.  We collaborate with the Department of Engineering on several translational research projects and medical device projects.  Our division has podium presentations at every national, regional, and local vascular meeting as well as at national and international surgical society meetings and trauma society meetings.  Applicants with a strong interest in research will have no shortage of mentorship and projects to work on during their training.

    Keck Medical Center

    Keck Medical Center (KMC) includes a 401-bed university-affiliated teaching hospital as well as the 60 bed Norris Cancer Institute. KMC is located on the Health Sciences Campus which includes the USC Keck School of Medicine and the School of Pharmacy. In any given year, over 18,000 outpatient and inpatient procedures are performed at KMC. As a tertiary/quaternary referral center for California, Nevada and Arizona, KMC provides care for the most acute and complex medical and surgical problems. In 2020, Keck Medical Center was number 18 in the US News and World Report hospital rankings. Both The USC Comprehensive Aortic Center and the Limb Preservation/SALSA Programs are located at KMC.

    At any given time at KMC there are two senior vascular surgery residents/fellows as well as a PGY3 and PGY1 surgical resident. The senior residents/fellows are responsible for daily management of the vascular surgery service which includes a high percentage of patients requiring complex and re-do vascular surgery procedures. Vascular surgery faculty also perform a wide range of endovascular procedures, including aortic stent grafts, percutaneous angioplasty/stents and diagnostic angiography. The residency team is also fully integrated into the activities of The USC Comprehensive Aortic Center and Limb Preservation/SALSA programs. KMC has an active ICAVL accredited noninvasive vascular laboratory directed and managed by USC vascular surgery faculty.
