Expanding the Teaching Toolbox: Characterizing Utility of a Web-Based Lecture Series in Educating Future Colleagues and Referrers about the Field of IR.

J Vasc Interv Radiol 2019 Apr;30(4):589-593.e3

Department of Radiology and Biomedical Imaging, University of California, San Francisco, 1001 Potrero Ave., San Francisco, CA 94110.

Opportunities for interventional radiology (IR) education and exposure remain limited at medical institutions without a local IR presence, thereby excluding a medical student population with potential to pursue careers in IR or become referring providers to IR. The purpose of this study was to evaluate the efficacy of a Webinar-based IR elective as an educational tool for outreach to US medical schools lacking local preclinical IR exposure. Our early results indicate that a Webinar-based IR lecture series can serve as an effective method for educating future physicians about the field of IR and when to consult IR for patient management.

Interventional Radiology Unit and Department of Medical Imaging, University Hospital Heraklion, University of Crete Medical School, Voutes, 71110 Heraklion, Greece. Electronic address:

Purpose: To evaluate foot perfusion in patients with critical limb ischemia (CLI) using quantitative perfusion multi-detector-row CT and estimate perfusion parameter changes before and after percutaneous transluminal angioplasty (PTA).

Materials And Methods: This prospective study investigated 13 patients (10 men; median age, 72 y; range, 51-84 y) with CLI who underwent CT foot perfusion examinations with a 128-slice dual-energy CT scanner 1 day before and 1 week after PTA. Key parameters such as permeability surface (PS), blood volume (BV), and blood flow (BF) were analyzed and compared statistically. Read More

Impact of Polar Renal Artery Coverage on Early Renal Function after Chimney Endovascular Aortic Aneurysm Repair.

J Vasc Interv Radiol 2019 Apr;30(4):539-545

Centre Méditerranéen de Médecine Moléculaire (C3M), Université Côte d'Azur, CHU, Inserm, Nice, France.

Purpose: To evaluate impact of polar renal artery coverage on early renal function after chimney endovascular aneurysm repair (EVAR).

Materials And Methods: Consecutive patients who underwent chimney EVAR for treatment of asymptomatic juxtarenal abdominal aortic aneurysm were retrospectively included. Estimated glomerular filtration rate (eGFR) was recorded before the intervention and at 1-, 5-, 7-, and 30-day follow-up. Read More

Early and Late Outcome of Common Iliac Aneurysms Treated by Flared Limbs or Iliac Branch Devices during Endovascular Aortic Repair.

J Vasc Interv Radiol 2019 Apr;30(4):503-510

Department of Vascular Surgery, University of Bologna Alma Mater Studiorum, Policlinico S. Orsola-Malpighi, via Massarenti 9, Bologna 40138, Italy.

Purpose: To compare perioperative and long-term outcomes of endovascular aneurysm repair (EVAR) with flared limbs (FLs) vs iliac branch devices (IBDs) for common iliac artery aneurysm to determine possible differences in outcome.

Materials And Methods: From 2012 to 2017, all patients with standard EVAR with FLs and aortoiliac anatomy fit for implantation of IBDs were retrospectively selected and compared with patients with standard EVAR and IBDs.

Evaluation of Venous Stenosis Angioplasty in a Murine Arteriovenous Fistula Model.

J Vasc Interv Radiol 2019 Mar 19. Epub 2019 Mar 19.

Vascular and Interventional Radiology Translational Laboratory, Department of Radiology, Mayo Clinic, 200 First Street SW, Rochester, MN 55905; Department of Biochemistry and Molecular Biology Mayo Clinic, Rochester, Minnesota; Department of Radiology, Vascular and Interventional Radiology, Mayo Clinic, 200 First St SW, Rochester, Minnesota, 55905. Electronic address:

Purpose: To develop a clinically relevant model of percutaneous transluminal angioplasty (PTA) of venous stenosis in mice with arteriovenous fistula (AVF); to test the hypothesis that there is increased wall shear stress (WSS) after PTA; and to histologically characterize the vessels.

Materials And Methods: Thirteen C57BL/6J male mice, 6-8 weeks old, underwent partial nephrectomy to create chronic kidney disease. Twenty-eight days later, an AVF was created from the right external jugular vein to the left carotid artery. Read More
