Objective To compare the efficacy and safety of biradial access with combined radial and femoral access for interventional treatment of coronary chronic total occlusion (CTO).
Methods Patients who underwent coronary artery CTO intervention via bilateral radial access or combined radial and femoral access were included. Baseline data, surgical strategy, intraoperative parameters (surgical time, exposure time, radiation dose, contrast agent dosage, and heparin dosage), surgical success rate, and postoperative complications between two groups of patients were compared.
Results A total of 336 patients were included in this study, of which 76.8% completed interventional treatment via biradial access. Compared with combined radial and femoral access group, procedural duration, contrast volume and heparin consumption were reduced in biradial access group (P < 0.05). The success rate of surgery in the bilateral radial access group was not inferior to that in the combined radial and femoral access group (P> 0.05). In addition, biradial access compared with combined radial and femoral access was associated with a significant reduction in incidence of coronary perforation, access vascular complications and acute kidney injury (P < 0.05).
Conclusions Due to its efficacy and safety in CTO-PCI, biradial access is widely applied in current CTO-PCI and deserved broader application in the future.
