Radiology IR Resident and Dr. Scott Trerotola in IR Surgery

Education, Mentorship and Leadership in the field of IR

Penn Medicine's Department of Radiology is one of the first in the country to offer the Dual Certificate IR/DR Integrated residency.

Interventional Radiology at the Hospital of the University of Pennsylvania (HUP) offers three separate Interventional Radiology residency tracks: A five-year year integrated interventional and diagnostic radiology residency program, a one-year independent IR residency program and a two-year independent IR residency program.

The Penn Interventional Radiology residency programs provide a diverse and professionally fulfilling foundation from which to launch an Interventional Radiology career. Residents have a unique opportunity to develop the knowledge and clinical skills necessary to prepare them to be leaders in the field of Interventional Radiology. Residents find themselves in cases, clinic and conferences alongside world-renowned physicians in a premier academic medical center. Our residents can become involved in a multitude of research opportunities led by faculty with a strong interest in advancing the field of Interventional Radiology. Many of our graduates have gone on to become heads of interventional radiology divisions in both the academic and private sectors, successful entrepreneurs, leading clinicians and researchers in the field.

The majority of a resident’s time is spent at the academic university hospital setting at HUP where the IR case volume is approximately 150 patient encounters per week. Candidates are exposed to more of a community radiology setting at the Philadelphia Veterans Affairs, Penn Presbyterian and Pennsylvania hospitals where the combined case volumes are approximately 120-130 patient encounters per week. The program also offers the unique opportunity to gain exposure to Pediatric Interventional Radiology at the world-famous Children's Hospital of Philadelphia.

Integrated Interventional/Diagnostic Radiology Residency Program

Integrated residents train alongside their diagnostic radiology resident colleagues during the R1 – R3 years. During these first three years, residents spend two blocks a year in interventional radiology. R4 and R5 years are devoted to interventional radiology. During the R4 year, residents spend one block in the ICU, six blocks in the IR department, and multiple blocks in IR-related areas, including research and clinical electives. The R5 year is dedicated to IR training with the majority of blocks spent in the IR suite. Residents also rotate through our very busy Interventional Radiology clinic.

At the end of the five years, residents complete approximately 24 dedicated IR rotations and also satisfy all requirements for completion of a diagnostic radiology residency. Therefore at the end of residency, residents are board eligible for both Interventional Radiology and Diagnostic Radiology.

Independent Interventional Radiology Residency Programs

The University of Pennsylvania offers both one- and two-year Independent Radiology Residency tracks. The one-year program is designed for trainees who have satisfied ESIR requirements during their diagnostic radiology residency and mimics the R5 year of the Integrated IR/DR Residency Program. The two-year program is for trainees who have not satisfied the ESIR requirements and is tailored to trainees who have spent time in their diagnostic residency focused on research.

Either the one- or two-year program prepares trainees to sit for the DR/IR combined certificate examination.

Clinical Work

The Interventional Radiology Residency programs offer exposure to a wide variety of patient care experiences. Trainees gain extensive experience and expertise in diagnostic and therapeutic procedures in multiple areas including:

  • Arterial disease — Endoleak embolization, arterial thrombolysis, critical limb ischemia
  • Gender-specific health — Uterine artery embolization, pelvic congestion syndrome treatment, fallopian tube recanalization, prostate artery embolization, varicocele embolization
  • GI tract — Gastric and jejunal feeding tubes, gastrointestinal hemorrhage
  • GU tract — Nephrostomy, ureteral stent placement/removal, complex access for nephrolithiasis
  • Lymphatic interventions — Lymphangiography, thoracic duct embolization, liver and abdominal lymphatic embolization
  • Liver and biliary tract — Transjugular liver biopsy, TIPS, BRTO, portal vein recanalization, percutaneous biliary drainage, biliary stone management
  • Oncology — Percutaneous ablation, chemoembolization, radioembolization, portal vein embolization, Denver shunt placement
  • Non-oncologic embolotherapy — Pulmonary AVM (HHT), vascular malformation therapy, trauma and gastrointestinal bleeding
  • Pain management- — Percutaneous sympathectomy, kyphoplasty/vertebroplasty 
  • Venous disease — Acute DVT thrombolysis and chronic DVT recanalization, IVC filter placement, complex IVC filter removal, superficial venous ablation, microphlebectomy, and sclerotherapy

Home to Leading-Edge Facilities

At the Hospital of the University of Pennsylvania (HUP), Penn Interventional Radiology boasts four state-of-the-art interventional radiology suites, one CT-fluoroscopy suite, two C-arm suites, two procedural CT scanners, a pre-procedure suite, and a large post-procedure recovery suite. The Perelman Center, across the street from HUP, has two C-arm suites, a venous ablation suite and a dedicated Interventional Radiology Clinic with 4 clinic rooms and provider workroom areas. Ultrasound is available in all of the interventional suites and clinic.

Trainees have a dedicated office and workspace that includes lockers, desks, and computers. Digital workstations for reviewing imaging studies such as CT scans and MRIs are available in the Interventional Workroom, resident’s office and clinic.

The Penn Presbyterian Medical Center has three state-of-the-art IR suites. The VA Medical Center and Pennsylvania Hospital have two state of the art IR suites each, all equipped with the latest technology. Residents have access to all the resources, activities, and facilities that is expected of world-class academic center.

Educational Resources and Conferences

The residency programs consist of daily educational conferences and rounds. Conferences include weekly didactic lectures in interventional radiology, IR Chief Rounds (a case-based conference), liver tumor conference and biweekly dialysis access conference. There are monthly Morbidity and Mortality, research and coding conferences. Each day fellows review the previous day's cases with the attending staff to learn about the technical and clinical points important to the cases.

Both clinical and laboratory research are performed at the University of Pennsylvania. All residents have the opportunity to participate in research with a mentor within the program; this often leads to residents presenting papers at the annual Society of Interventional Radiology (SIR) and many other meetings. Interventional Radiology division members speak at several annual Continuing Medical Education (CME) courses which residents are encouraged to attend.
