RESUMO
Introduction: The radial artery is currently the most widely used access site for PCI procedures both acute and stable patient settings. Thanks to advantages in pharmacological therapy as well as in interventional devices, the rate of ischemic complications following PCI has significantly decreased. Nevertheless, this has been counterbalanced by an increased risk of periprocedural and late bleeding event, that can occur both at access and non-access sites. Choice of access site for PCI is of paramount importance to reduce the risk of access-related bleeding events. Areas covered: The aim of this review is to provide an overview of the actual available evidence comparing the transradial versus transfemoral approach to reduce hemorrhagic events. The most robust evidence comes from large randomized trials, partly also from observational registries, which compared the transradial and transfemoral approach. Expert opinion: Results show that radial access has proved to be decisive in reducing the incidence of hemorrhagic events. Furthermore, it showed a significant reduction in mortality and AKI compared to transfemoral access. However, increased experience in the use of the radial approach has led to less practice in the use of the femoral approach, which may be useful in cases of emergency, complications or inability to use the radial artery.
