Background: This study investigated the safety and efficacy of coronary angiography (CAG) and percutaneous coronary intervention (PCI) via distal transradial artery access (d-TRA).
Methods: For this single-centre prospective cohort study, a total of 1066 patients who underwent CAG or PCI procedures from September 2019 to November 2020 were included. Patients were divided into two groups: the d-TRA group (346) and the conventional transradial artery access (c-TRA) group (720) based on access site. A total of 342 pairs of patients were successfully matched using propensity score matching (PSM) for subsequent analysis.
Results: No significant differences in puncture success rate, procedural method, procedural time, sheath size, contrast dosage or fluoroscopy time were noted between the two groups. The puncture time in the d-TRA group was longer than that in the c-TRA group (P < 0.01), and the procedure success rate was lower than that in the c-TRA group (90.94% vs. 96.49%, P = 0.01). The haemostasis time in the d-TRA group was shorter than that in the c-TRA group (P < 0.01), and the visual analogue scale (VAS) was lower than that in the c-TRA group (P < 0.01). In addition, the prevalence of bleeding and haematoma in the d-TRA group was lower than that in the c-TRA group (1.75% vs. 7.31%, P < 0.01; 0.58% vs. 3.22%, P = 0.01, respectively). No significant difference in the incidence of numbness was noted between the two groups. No other complications were found in two groups.
Conclusion: d-TRA is as safe and effective as c-TRA for CAG and PCI. It has the advantages of improved comfort and fewer complications. Trail registration Chinese Clinical Trial Registry, ChiCTR1900026519.

Background: Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis fistulas, addressing the existing gap in comprehensive literature.

Background: Transradial secondary access (TR-SA) may serve as an alternative to the traditional femoral secondary access (TF-SA) for pigtail placement in transcatheter aortic valve replacement (TAVR).
Objectives: The aim of this study was to assess the incidence of secondary access-related vascular complications after TR-SA or TF-SA in TAVR.
Methods: The PULSE (Plug or sUture based vascuLar cloSurE after TAVR) registry retrospectively evaluated data of 10,120 patients who underwent transfemoral TAVR at 10 heart centers from 2016 to 2021.

Background And Purpose: Transradial access (TRA) for cerebral angiography has become more popular due to fewer complications and greater patient comfort compared to transfemoral access. However, the frequency and nature of neurologic complications linked to TRA remain unclear. This study aimed to determine the incidence of symptomatic neurologic complications after transradial cerebral angiography, identify risk factors, and characterize clinical and imaging features of these complications.

Radial artery occlusion (RAO) is a relatively common but benign complication following transradial endovascular approaches. Radial artery thrombectomy offers a potential strategy for re-access. Transradial access in the occluded vessel has been described as safe and feasible in recent literature; however, the step-by-step technical details have not been defined.

Introduction: Given radial artery conduits are increasingly utilized for coronary artery bypass grafting (CABG), avoiding transradial access (TRA) for invasive coronary angiography (ICA) may benefit patients who ultimately undergo CABG. We sought to predict the likelihood of severe multivessel disease (MVD) before ICA to guide this decision.
Methods: This was a single-center study of 1485 patients with stable symptoms who underwent ICA.
