Transradial access(TRA)for performing interventional diagnosis and treatment can reduce access site complications.However,TRA can still cause complications in the operated limb,including radial artery spasm,radial artery perforation,hemorrhage,hematoma,radial artery dissection,osteofascial compartment syndrome,nerve injury,pseudoaneurysm,arteriovenous fistula,and radial artery occlusion,among which radial artery spasm is the most commonly seen.At present,the clinical recognition,prevention and treatment of complications of surgical limbs are still insufficient.Therefore,this consensus aims to make a detailed introduction about the identification,prevention and nursing of nine major types of complications of the surgical limb in interventional diagnosis and treatment procedures via radial artery access,to propose 24 recommendations which may provide a reference for medical institutions in carrying out the nursing care for complications of the surgical limb in interventional diagnosis and treatment procedures via radial artery access,and to reduce the occurrence of complications in patients.(J Intervent Radiol,2024,33:465-471)
