Management of vascular surgery in treatment of transradial access-related interventional therapy complications

Objective Transradial access (TRA) has become the primary access for coronary intervention. With the increase in the number of patients with TRA, its complications have attracted the attention of clinicians.TRA-related complications can be categorized into intraoperative and postoperative complications according to the period of occurrence, and into hemorrhagic and nonhemorrhagic complications according to whether bleeding events are involved or not. If intraoperative complications such as radial artery entrapment, perforation, spasm, and catheter bending and fracture can be recognized early, they can be intervened by endoluminal methods and have a good prognosis. Hematoma, pseudoaneurysm and arteriovenous fistulae can occur as a result of intraoperative complications and improper management of the puncture point, for which early surgical intervention should be made if conservative methods fail to work in order to avoid forearm osteofascial compartment syndrome leading to amputation. Radial artery occlusion, as the most common TRA-related complication, patients may not have hand ischemia symptoms, but radial artery patency is clinically important, so radial artery occlusion should be monitored, detected and intervened as early as possible. Currently, there are few studies on TRA-related complications and a limited number of cases, and large-sample, high-quality clinical studies are urgently needed.
