SHOW NOTES

Dr. Rami Tadros is a vascular surgeon and Site Director of Endovascular Aortic Surgery at Mount Sinai Hospital. Dr. Tadros begins by discussing how often he uses radial access in his practice, how current wire and catheter technology limits the potential of radial access, and how evolution of these devices (such as increased length and improved sizing for transradial tools) is on the horizon.

Dr. Tadros also discusses the indications and specific advantages for radial access. He describes his device preferences, workflow, and workarounds for radial access. The doctors then take a deeper dive into lengths and sizing of the tools that are currently on the market. They offer some insight on maximizing distance while still maintaining pushability and taking into account the variety of patient anatomy. There is also a brief discussion on pedal access, risks associated with it, and closure complications.

Dr. Tadros covers specific clinical vignettes for treating PAD with radial access. There are limitations of the currently available devices, so it is important to plan for distal embolization and bailout stents.

We conclude the episode with some guidance for radial access. We review the required tools, the importance of confirming patency of the palmar arch, and the Barbeau test to inform radial access. Dr. Tadros also highlights the use of verapamil, heparin, and nitroglycerin to minimize the risk of vessel spasm.
