Interventional Radiology-Independent Residency Program

The University of Michigan Interventional Radiology Independent Residency Program is ACGME accredited and approved for 1 and 2 year positions. Our program plans to match up to 2 candidates per year into the 2nd year of training (1 year program). Candidates who have completed an Early Specialization in Radiology (ESIR) track are eligible to apply.

The Vascular Interventional Radiology (VIR) division covers 4 sites with 10 state-of-the-art vascular interventional angiography suites and 3 modern neuro-interventional suites.

You will perform the entire gamut of image guided minimally invasive procedures in a clinically-based VIR practice which includes a PAD, venous, interventional oncology, vascular malformation, neuro-interventional and general IR clinics. Vascular interventional radiologists are an integral part of the multidisciplinary aortic program (including dissection) team. An independent rotating multidisciplinary PAD service and an independent venous service are established with participation of several of the VIR faculty. The VIR division uses up to 3 angiography-OR suites and a full hybrid IR/OR suite in the Frankel Cardiovascular Center (CVC) for angiography and fluoroscopic guided procedures. The Children’s and Women’s Hospital, with its modern bi-plane IR suite is a major international referral center for pediatric and adolescent vascular disease including aortic coarctation, vasculitis, visceral artery stenosis, and vascular malformations. In addition, an active pediatric portal hypertension clinic and multidisciplinary board are established.

Our VIR practice includes venous access, oncologic, transplant, hepatobiliary, GU and GI interventions. The IO service performs Y90 radioembolization, TACE, metastatic embolization, peripheral skeletal bone ablation and cement augmentation, visceral tumor ablation, endocrine venous sampling, and AML embolization. Clinic based practice and involvement in multiple multidisciplinary tumor boards, pediatric and adult portal hypertension clinics, and transplant boards is integral to our division. The VIR division uses 5 angiography suites (1 combined CT-angiography rooms and 2 additional rooms with cone-beam CT). The Ann Arbor VA Hospital is the largest VA hospital in the state and has two state-of-the art angiography suites and a dedicated procedural CT.


The objective of the program is to provide residents with a comprehensive, supervised educational experience in vascular and interventional radiology according to the ACGME-approved program requirements. The training program offers didactic and clinical experiences that encompass the full clinical spectrum of vascular and interventional radiology.

With one of the highest trainee to procedure ratios in the country, trainees will have the opportunity to carry out all necessary procedures under close supervision, including pre-procedure evaluation of patients, various vascular and nonvascular procedures, consultation with clinicians, admission to the interventional radiology service, and post-procedure follow-up care. Trainees will be instructed in proper use of physiologic monitoring, noninvasive vascular imaging, antibiotics, narcotics, conscious sedation, and other drugs commonly used in VIR. Examples of vascular interventional procedures include infusion therapy, catheter-directed thrombolysis, mechanical thrombofragmentation, embolotherapy, angioplasty and related percutaneous recanalization procedures for arterial and venous occlusions, stent placement, filter insertion, foreign body removal, TIPS, thoracic endografting, percutaneous fenestration for aortic dissection, and central venous access. Examples of nonvascular procedures include percutaneous and transvenous biopsy, abscess drainage, biliary interventions (cholecystostomy, biliary drainage, stone extraction, dilation, choledochoscopy, and stenting), GI interventions (percutaneous gastrostomy, gastrojejunostomy, jejunostomy, cecostomy, and dilation), and genitourinary interventions (percutaneous nephrostomy, dilation, and stone extraction), and vertebroplasty.

VIR conferences include daily morning rounds, monthly IR M&M, and vascular basic science lecture.

Time is also allotted for training in MRA and CTA. Trainees are encouraged to participate in ongoing clinical and basic research projects.
