Please note that you can use these presentations to introduce IR to your colleagues or trainees. We simply ask that you keep the CAIR background and contact information as well as the slide mentioning the authors.

Real life case

  • A 50 year old man presents to the emergency department with a history of high speed motor vehicle collision
  • CT scan shows a large liver laceration with active bleeding from a hepatic artery branch
  • You are the ER doctor on shift and you have managed to stabilize his vitals but the patient is still requiring ongoing blood transfusions
  • What is the appropriate management?
  • If you said “Surgery”, you would be wrong
  • This case will be managed by interventional radiology

Introduction

Interventional Radiology (IR) is a relatively new medical field which performs minimally invasive therapies under imaging guidance.
Interventional radiologists are physicians who perform these minimally invasive treatments.
IR is currently a subspecialty of Radiology: interventional radiologists have completed a diagnostic radiology residency, followed by subspecialty/fellowship training in IR.

What do we do?

To view the images for the procedures mentioned below, please download the presentation.

  • Vascular/angiography

Coiling of splenic artery pseudoaneurysm

  • Peripheral Vascular Disease

Angioplasty and stenting of superficial femoral artery

  • Interventional Oncology

Hepatocellular carcinoma can be treated with Transarterial Chemoembolization
(TACE) or Radiofrequency Ablation (RFA)

  • Gastrointestinal, Genitourinary, Hepatobiliary

Percutaneous gastrostomies, nephrostomies, biliary drainages

  • Women’s health

Uterine fibroid embolization: before and after

  • Biopsies and Drainages

Diverticular Abscess Drainage

  • Musculoskeletal

Steroid injections for pain relief

  • Neurointerventional

Basilar artery occlusion treated with angioplasty and stenting

Is IR the right career for me?

  • Desire to treat patients and improve morbidity/mortality
  • Prefers performing minimally invasive treatments instead of major surgeries
  • Strong empathy for patients and interest in patient care
  • A team player who enjoys working in a multidisciplinary setting
  • Interest in creative problem-solving and “thinking on the fly”
  • Preferably also enjoys diagnostic radiology and “solving puzzles” with imaging
  • Not afraid of longer work hours than diagnostic radiology, but lifestyle is usually still better than surgery

How do I become an interventional radiologist?

Current training pathway:

  • Diagnostic Radiology Residency (5 years)
  • IR Fellowship (1 year)

Training pathway will be changing soon:

  • In the near future, the training pathway will involve increasing the duration of IR training to 2 years, but 1 year will be double-counted within the diagnostic radiology training. This change will allow for more training in clinical skills and IR related imaging. Total length of time will stay the same (6 years).
  • In the more distant future, IR may become its own specialty and have its own residency program

I’m curious … what now?

How to learn IR

IR is an exciting constantly evolving field, so to become a good interventional radiologist, a trainee must be proactive in seeking out learning opportunities throughout medical school, residency, and fellowship. There are many ways to learn IR, and they are detailed below. The list below is by no means comprehensive, and trainees are encouraged to try other resources as well. If you have suggestions for good resources that are not listed here, please feel free to contact us, and we will add it to the list below!

Textbooks:

  • Handbook of Interventional Radiologic Procedures (Kandarpa and Machan): This is a great pocketbook and serves as a quick reference during your IR rotations as a resident/fellow. Organized by procedure, the book gives you a quick summary of the pre-procedural work-up (including indications, contraindications, consent), procedure technique (step-by-step), and post-procedural care and follow-up.
  • Vascular and Interventional Radiology: The Requisites (Kaufman and Lee): This is a textbook in the Requisites Series, and offers much more detail on each procedure than the Handbook. It provides good explanations and teaches the fundaments of IR, great for residents and fellows.
  • Vascular and Interventional Radiology (Valji): This is an alternative textbook to the Requisites. Some trainees prefer this book over the Requisites, but they are both great books to learn the fundamentals.
  • Atlas of Vascular Anatomy (Uflacker): This is a great imaging atlas to learn the details of vascular angiographic anatomy, which you will not find in standard imaging anatomy textbooks. The image quality is a little outdated, since this current edition was published in 2006.

Online/electronic resources:

  • Society of Interventional RadiologyThe United States society for interventional radiologists – contains a wealth of information on IR procedures, physicians, and the annual SIR scientific meeting.
    http://rfs.sirweb.org/ – This is the SIR Resident and Fellow Section (RFS), which is targeted to trainees, providing education on IR procedures, clinical skills development, and IR fellowships and residencies in the US.

Conferences:

Attending conferences is a great way to learn IR. At the conference, you will find dedicated content for trainees, talks on IR fundamentals, and cutting-edge scientific exhibits. It is also a great way to directly interact with interventional radiologists. Common conferences that trainees go to would be CAIR (Canadian) and SIR (US).

Please note that there are travel scholarships/grants for trainees for both the CAIR and SIR conferences:

  • For CAIR: If you are a resident or fellow, you can submit an interesting case and present it at Fellows Day as part of the meeting. If your case gets accepted, you earn a free trip to the meeting. Please contact ciraservice@ciraweb.org for more information.
  • For SIR: They have medical student and resident travel scholarships, which Canadian trainees are eligible for. Please visit the SIR annual meeting webpage for more details.

Clinical experience:

No matter how much theory and how many textbooks you read, the clinical experience is most important and irreplaceable. IR is definitely a procedural subspecialty – the more hands-on experience you get the better.

Try to maximize your exposure both to the clinical and procedural aspects of IR through shadowing, core rotations, and electives.
