PEDREROS, Pablo et al. Long term evaluation of functional and structural changes of the radial artery used as access for cardiac interventional procedures. Rev Chil Cardiol [online]. 2010, vol.29, n.2, pp.193-198. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602010000200004.

Background: the radial artery is a common and safe access site for endovascular procedures. There has been no adequate evaluation of the radial artery integrity following the procedure. Aim: to evaluate the long term functional and structural status of the radial artery use for cardiac interventional procedures Methods: 33 patients with coronary artery disease had coronary angiography and/or PTCA using the radial artery approach. After 6-10 months the functional and structural status of the artery was evaluated by comparison to the contra lateral artery Results: Three (9%) arteries were occluded. No thickening of the arterial wall distal to the puncture site was observed. Diameters were 2.6 ± 0.7 vs 2.8 ± 0.35mm (punctured vs control) distally and 2.8 ± 0.35 vs 2.5 ± 0.7mm proximally. Respective peak systolic flow velocities were 54 ± 16 vs 50 ± 14 cm/sec (NS) and resistance indexes were 0.83±0.1 compared to 0.67±0.1 (NS) Conclusion: A low % of radial arterial occlusion is observed following use of the radial artery following cardiovascular interventions. Patent arteries showed no structural or functional limitations at long term evaluation.
