Since the development of percutaneouscoronaryintervention (PCI), the femoral artery has been used as the conventional route, which has the advantages of easy access and relatively simple operation, but it also has the disadvantages of long postoperative bed rest, restricted position, high incidence of postoperative bleeding and vascular complications ( 3-5%). These local complications sometimes require blood transfusion or surgical repair, which leads to prolonged hospitalization, increased hospital costs, and in severe cases, even permanent functional impairment or death. TRI has a fifteen-year history since the first transradial intervention (TRI) was performed by Dr. Keimeneij at the OLVG (OnzeLieveVrouweGasthuis) Center in Amsterdam in 1992. Several domestic and international studies have demonstrated that there is no significant difference between TRI and TFI in terms of procedure time and success rate, cardiac complications, equipment consumption, and fluoroscopy time, while TRI has the advantages of less bleeding and vascular complications, less patient pain, shorter hospital stay, and reduced hospital costs. The transradial route provides another ideal route for coronary intervention. In recent years, due to the improvement of interventional devices and the inherent advantages of radial artery puncture, TRI has gradually gained the attention and adoption of interventional cardiologists in some countries, and some interventional centers in large hospitals have adopted radial artery as the preferred route for PCI and have made great progress in clinical application.
