Abstract 9273: Meta-Analysis of Stroke After Transradial Versus Transfemoral Artery Catheterization
Objectives: To assess the risk of stroke after transradial (TR) versus transfemoral (TF) artery cardiac catheterization.
Background: TR catheterization is gaining popularity due to its association with lower bleeding and access site complications, improved patient comfort, and lower costs compared to TF catheterization; however, there is concern that TR catheterization may be associated with an increased risk of neurological complications.
Methods: We conducted a meta-analysis of randomized studies published until 2013 reporting risk of stroke in TR vs. TF catheterization.
Results: Data from 11,273 patients in 13 studies were collated. The majority of patients were men, and 8,987 (79.7%) were enrolled in acute coronary syndrome trials. Very few patients had a history of prior coronary artery bypass grafting, and approximately 2/3 of patients underwent percutaneous coronary intervention. Stroke occurred in 25 of 5,659 patients in the TR group, vs. 24 of 5,614 patients in the TF group. There was no difference in stroke rates between the TR and TF groups (Figure , risk difference 0.00%, 95% confidence interval -0.29% - 0.25%, p=0.88). This finding was consistent in a number of sensitivity analyses (excluding non-ST elevation acute coronary syndrome (ACS) trials, non-ACS trials, trials reporting in-hospital events or 30-day events, trials requiring radial expertise).
Conclusions: TR catheterization is not associated with a significant increase in stroke compared to TF catheterization.
