Show Notes

In this episode, Dr. James Caridi joins Dr. Christopher Beck to discuss the benefits of using CO2 for an angiography as well as some important tips for proper use. Dr. Caridi mentions some of the reasons for choosing CO2 rather than contrast, including its solubility, low viscosity, and buoyancy.

He also speaks about CO2 angiography approaches for imaging difficult to access vasculature. Dr. Caridi also speaks to specific uses of CO2 angiography for use for mesenteric angiography and how CO2 angiography can improve the sensitivity for detection and localization of GI bleeds. Dr. Caridi and Dr. Beck also discuss some non-vascular uses for CO2 angiography as well as a technique for imaging with CO2 without having to give up wire access.

We talk through safely preparing a delivery system and gently injecting CO2 to prevent/reduce reflux in the patient if needed. Finally, we go into some notes concerning dialysis, contrast induced nephropathy, and some instances when CO2 angiography should not be used.
