OP-91 Transradial Catheterization Decreases the Radial Artery Luminal Diameter and Impairs Vasodilatation Response at the Access Site Late after the Intervention: an Observational Study
Objectives
The present study aimed to evaluate the late term changes in radial artery luminal diameter (RAD) and vasodilatation response following transradial coronary intervention (TRI).
Background
TRI inducing a trauma to radial artery intima may trigger chronic phase vascular changes and lead to anatomical and functional impairment. There is controversial data whether the impairment persists or repairs later.

Methods
Fifty six consecutive patients undergoing TRI were enrolled prospectively. Baseline luminal diameter, flow associated dilatation (FAD) and nitroglycerin mediated dilatation (NMD) of the radial artery at the access site were measured before TRI by using high resolution ultrasound. Six months later; RAD, FAD and NMD were measured again at the same access site.
