Background and aim Transradial approach (TRA) is being used increasingly as the preferential vascular access site for both diagnostic and interventional procedures. However, concerns have risen about the risk of clinically meaningful neurologic complications. We aimed to assess the association between the risk of stroke/transient ischemic attack (TIA) and the transradial (vs. transfemoral) approach. Methods and Results Data from 16,710 cases included in a single centre prospective registry between January 2006 and November 2012 was analyzed. Radial procedures were considered as those in which the radial access was used either primarily ( n = 4,195) or after conversion ( n = 36). Potential cases with neurologic events were targeted by cross‐referencing patients who underwent both cardiac catheterization and cranial‐computed tomography (cranial‐CT) during the same admission episode ( n = 67). Procedure‐related events were defined as a definitive non‐CABG related stroke/TIA occurring within 48 hr of the procedure. TRA increased from 0.7% in 2006 to 75% in 2012. Total incidence of stroke/TIA was 0.16% and did not change over the study period ( P = 0.26). There was no significant difference in stroke/TIA rates between groups (0.165% vs. 0.160%; P = 1.0). After correction for baseline differences and propensity score matching, TRA was not an independent predictor of stroke/TIA (OR 1.21; 95% CI 0.49–2.98 and 1.3; 95% CI 0.55–3.54, respectively). Results were consistent in pre‐specified sub‐groups according to age (≥65 y.o. vs. younger), gender, interventional vs. diagnostic and ACS vs. stable. Conclusion Rates of documented stroke/TIA were low. Our observational study suggests that widening the use of the TRA is not associated with an increased risk of clinically relevant procedure‐related neurologic complications. © 2015 Wiley Periodicals, Inc.
