What are the structural and clinical consequences of radial artery puncture after catheterization?
While radial artery puncture causes ubiquitous acute vessel wall injuries, postprocedural radial occlusion is primarily associated with repeated puncture attempts rather than the acute injuries themselves.
Repeated attempts may raise radial occlusion risk; leaves open clinical relevance of chronic wall thickening.
After catheterization, radial artery puncture site is associated with increased intima and total wall thickness and with modest decrease of inner lumen diameter. Acute injuries of the vessel wall were ubiquitous, but contrary to repeated puncture attempts, did not seem to affect postprocedural radial occlusion or loss of pulsation.
