Abstract

Abstract : Background . This prospective study compared the success rate and safety of a distal transradial artery (dTRA) approach to that of the conventional transradial artery (TRA) for coronary angiography or percutaneous coronary intervention. Methods . From January 2019 to April 2020, nine hundred consecutive patients (height < 190 cm) scheduled for coronary angiography or percutaneous coronary interventions were randomly and equally assigned to receive either dTRA or conventional TRA catheterization. Results . Successful access was achieved in 96.00% and 96.67% of the dTRA and conventional TRA groups, respectively (P = 0.814 ). Compared with the TRA group, patients in the dTRA experienced significantly less hemostatic band removal time (150.5 ± 50.5 cf. 210.6 ± 60.5 min, P = 0.032 ); minor bleeding of the access site (2.44% cf. 6.44%, P = 0.038 ); hemostatic band cost (USD; 0.1 cf. 59.4, P = 0 ); and postprocedural radial artery occlusion (1.56% cf. 3.78%, P = 0.035 ). A lower body mass index was a higher risk factor for dTRA access failure (odds ratio = 0.79, P = 0.024 ), with a cutoff of 22.04 kg/m 2 . Conclusion. Compared to conventional TRA, dTRA had a comparable high success rate, with fewer associated complications. Clinicians should use the dTRA with caution in patients with low body mass index.
