Background: A new dedicated radial sheath (6-Fr Glidesheath Slender, Terumo, Japan) has almost the same outer diameter as a 7.5-Fr sheathless guiding catheter (Sheathless Eaucath, Asahi Intecc, Japan). We aimed to investigate the incidence and associated factors of radial artery occlusion (RAO) after transradial coronary interventions (TRI), comparing the new dedicated radial sheath and the 7.5-Fr sheathless guiding catheter.
Methods: The study enrollment period was from January 2015 to October 2015. New dedicated radial sheath was used for stable angina, whilst 7.5-Fr sheathless guiding catheter was for acute coronary syndrome. Doppler ultrasound study of the radial arteries was performed 2 days after the procedures. Correlations between RAO and all other parameters were analyzed by logistic regression analysis.
Results: Doppler examination revealed the incidence of RAO was not significantly different between the two groups (5.4 % vs 2.0%, P = 0.119). However, on logistic regression analysis, the use of 7.5-Fr sheathless guiding catheters (OR, 4.955; CI, 1.237-33.283; P = 0.022) and post-procedural radial diameter (OR, 0.142; CI, 0.035-0.504; P = 0.002) were identified as associated factors of RAO.
Conclusions: Both of the slender techniques utilized for TRI show the low incidence of RAO. A 7.5-Fr sheathless guiding catheter is more significantly associated with RAO than is a new dedicated radial sheath, 6-Fr Glidesheath Slender.
