Interventional Radiology


The Division of Interventional Radiology provides integral minimally invasive services for Duke Hospital, the surrounding community, and patients nationwide. We utilize radiologic guidance, comprised of fluorscopy, CT, and ultrasound, to perform an ever-growing spectrum of minimally invasive procedures throughout the body.

The range of services offered is vast including the following:

  • Embolization and ablation therapies for tumors in the liver, kidney, bone, and other organs
  • Gastrointestinal interventions for bleeding, aneurysms, or inadequate blood flow
  • Restoration of blood flow for patients with acute or chronic deep venous thrombosis
  • Interventions for pain palliation
  • Hemodialysis access management
  • Renal collecting system interventions
  • Treatment of female pelvis disorders
  • Management of bile duct and gallbladder pathology
  • Complex arteriovenous malformation management
  • Endovascular therapies for peripheral arterial disease
  • Providing enteral feeding access

The Duke interventional physicians utilize the most up-to-date technology and research data to perform the highest level of percutaneous minimally invasive image-guided services, while providing safe and effective patient care.

IR Residency

The Division of Interventional Radiology now offers three ACGME-accredited IR residency positions per year. For more information, please refer to the IR residency webpage.

IR Fellowship

The Division of Interventional Radiology offers a one year ACGME-accredited fellowship via the NRMP match. This is an intensive year of clinical training, providing the depth and breadth of cases needed to succeed and excel in all aspects of VIR practice. Our scope includes TIPS, UFE’s, tumor embolization, radioembolizations, cryoablations, RF ablations, complex peripheral arterial interventions, central venous reconstructions, AVM embolizations, embolization for pelvic congestion syndrome and varicocele, and numerous others. Historically, all fellows have graduated with well over 1000 cases per year. In addition to performing procedures under the supervision of an attending physician, fellows are also involved in interpreting noninvasive vascular imaging (MRA & CTA). Additionally, fellows participate in our weekly clinic, where patient’s are seen in consultation, pre-procedure, and post-procedure follow up.

The typical day begins with morning ’rounds’, which is a review of all scheduled procedures for the day amongst the attendings, fellows, residents, and scheduling staff. In terms of didactics, there is a weekly VIR fellows conference, weekly interdisciplinary vascular conference, weekly radiology grand rounds, and a weekly conference geared towards the residents on service, although fellows frequently attend this as well. Additionally, fellows are encouraged to attend the regional angio club meetings. The dedicated VIR fellows conference includes dedicated didactic lectures, journal clubs, mortality and morbidity rounds, and interesting case discussions. Fellows are on-call based on how many fellows are in that class (i.e. for four fellows, q4). However, on-call frequency is never more than q3.

Fellows are encouraged to participate in at least one research project, and the majority present at the Society of Interventional Radiology annual meeting. Fellows are expected to provide teaching for the residents during cases, with informal sessions outside of cases. Moonlighting opportunities are limited. Fellows receive four weeks of paid vacation.

Graduates of the Duke VIR fellowship have gone on to obtain coveted academic and private practice positions of their choice.

The Duke IR Fellowship is being replaced by the Integrated IR Residency training program. The last academic year for the fellowship program will be 2019-2020.
