The Particulars: In previous studies, transradial (TR) catheterization has been shown to have a lower risk of bleeding and access site complications when compared with transfemoral (TF) catheterization. TR catheterization has also been shown to improve patient comfort and cost less than TF catheterization. However, experts are concerned that the TR approach may have an increased risk of neurological complications.

Data Breakdown: Researchers conducted a meta-analysis of 13 studies containing stroke risk data on more than 11,000 patients who underwent TR or TF catheterization. The analysis found no difference in stroke rates between the two catheterization methods. The findings were also consistent in several sensitivity analyses.

Take Home Pearl: The risk of stroke appears to be similar following both TF and TR catheterization procedures.
