Radial artery sterile granulomatous reaction secondary to hydrophilic-coated sheath used for transradial cardiac catheterization: a case series.

Radial access has lower risk of vascular complication for cardiac catheterization and is rapidly replacing femoral access. There are few unique complications associated with this approach. We present 3 cases of sterile granulomatous reaction associated with a specific hydrophilic radial sheath and possibly contribution by radial wrist band [TR band; Terumo Medical used for hemostasis after sheath removal (2101 cotton tail lane somerset NJ, USA)]. Awareness of this association will help clinicians use appropriate preventive measures.
