Radial Access Evolution: Clinical Perspectives & Insights from the RAVI Registry
with Dr. Marcelo Guimaraes
In this episode of the BackTable Podcast, host Dr. Michael Barraza interviews guest Dr. Marcelo Guimaraes about the advantages and implementation of radial access in interventional radiology. Dr. Guimaraes is a vascular and interventional radiologist from the Medical University of South Carolina (MUSC).
Dr. Guimaraes shares insights on the adoption of radial access over femoral access, emphasizing its simplicity, safety, and the clear benefits recognized by younger interventionalists. He elaborates on the importance of education, partnership with the industry, and following a standard protocol to build a successful radial access program. The doctors also cover specific topics like the RAVI Registry outcomes, patient preferences for radial access based on a study, the cost-benefit analysis, and handling various challenges such as artery spasms and loops. Dr. Guimaraes advocates for radial access as the default method for embolization therapies, highlighting its efficacy across a range of procedures and patient conditions.
