Radial artery occlusion after transradial interventions: a systematic review and meta-analysis

Abstract Objectives: To investigate the incidence and factors influencing radial artery occlusion (RAO) post trans-radial access (TRA) for cardiac catheterization. Background: RAO may occur post trans-radial intervention and limits the radial artery as a future access site and precludes its use as an arterial conduit. In this study, we investigate the incidence and factors influencing the RAO in the current literature. Methods & Results: We searched MEDLINE and EMBASE for studies of RAO in TRA. Relevant studies were identified and data was extracted. Data was synthesized by meta-analysis, quantitative pooling, graphical representation or by narrative synthesis. A total of 66 studies with 31,345 participants were included in the analysis. Incident RAO ranged between
