title: Sterile radial artery granuloma after transradial cardiac catheterization.
abstract: Transradial cardiac catheterization has lower rates of arterial access site complications than transfemoral procedures. However, there are complications that are unique to the transradial route. We present the case of a sterile granuloma occurring at the site of radial arterial access as a reaction to the hydrophilic coating on the sheath. The clinical presentation was suggestive of an infected pseudoaneurysm. Awareness of this entity may help clinicians avoid unnecessary surgical procedures, as these granulomata are transient self-limiting reactions.
