Long-term consequences of trans-radial catheterization on the radial artery

Le résumé fourni par la source

Background: The radial artery (RA) is often utilized for diagnostic coronary angiography and percutaneous intervention. Recent high-level evidence supports RA use in preference to saphenous vein as a conduit for coronary revascularization. Aim: To demonstrate gross and histologic changes of the RA following transradial access. Methods: We present two patients who had open RA harvest for coronary bypass surgery after transradial catheterization. Results: Examination 8 years after transradial catheterization demonstrated thickened intima and dissection, and examination 12 years following transradial catheterization with percutaneous coronary intervention demonstrated chronic dissection with thickened intima and near occlusion of the lumen. Conclusion: Transradial access via the RA, even after several years, is associated significant injury, making it unusable as a conduit for surgical coronary revascularization. A RA that has been utilized for catheterization should not be considered for coronary revascularization.
