The effect of transradial coronary catheterization on upper limb function

Objectives The aim of this study was to analyze the change of upper limb function when percutaneous coronary procedures were performed through the radial artery. Background It is currently unknown if upper limb function is affected by transradial (TR) catheterization. Methods Between January 2013 and February 2014, upper limb function was assessed in a total of 338 patients undergoing coronary catheterization in an ambulatory setting (85% radial approach, 15% femoral approach). Upper limb function was assessed with the self-reported shortened version of the Disabilities of Arm, Shoulder, and Hand questionnaire. The presence and severity of upper extremity cold intolerance was assessed with the self-reported Cold Intolerance Symptom Severity questionnaire. Both questionnaires were completed before the catheterization and at 30-day follow-up. Higher scores represent worse upper limb functionality or symptoms. The nonparametric Wilcoxon signed-rank test was used to assess the change of upper limb function and symptoms over time. Results Upper limb function did not change significantly over time when catheterization was performed through the radial artery (p = 0.06). The number of procedure-related extremity complaints that persisted during 30-day follow-up were not different between both access groups (TR access 10.5%, transfemoral access 11.5%; p = 0.82). The upper extremity was not affected by cold intolerance after TR access at 30-day follow-up (p = 0.91). Conclusions Upper limb function was not affected when coronary catheterizations and interventions were performed through the radial artery
