Feasibility of Distal Radial Access in High Bleeding Risk Patients Who Underwent Percutaneous Coronary Intervention.
Korean Circ J

Division of Cardiology, Department of Internal Medicine, Yonsei University College of Medicine and Cardiovascular Center, Yongin Severance Hospital, Yongin, Korea.
Backgrounds And Objectives: The distal radial access (DRA), a potential alternative to the trans-radial approach (TRA), may offer advantages in terms of access site complications due to its smaller vessel diameter, especially for high bleeding risk (HBR) patients. This study aims to investigate the feasibility of DRA in HBR patients.
Methods: Based on data from the KODRA registry, a prospective, multicenter cohort, this study analyzed 1,586 patients who underwent successful percutaneous coronary intervention (PCI) via DRA.
Endovascular Treatment of Malfunctioning Dialysis Fistulas: A Multicenter Retrospective Analysis Comparing Transradial and Conventional Transvenous Access.
Catheter Cardiovasc Interv

Radiology Unit, University Hospital Dulbecco, Catanzaro, Italy.
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.

- Transradial arterial access offers advantages over femoral access in coronary interventions, including reduced bleeding, improved patient comfort, and shorter hospital stays, leading to increasing interest in its use for peripheral vascular procedures.
- Despite its benefits, challenges remain, and ongoing development of specialized equipment is necessary for effective use in these interventions.
- Current studies suggest that transradial access is generally safe and associated with fewer complications, but further large-scale randomized trials are needed to fully understand its impact on patient outcomes and to identify suitable patient selection criteria.
Enhancing neuroprosthesis calibration: the advantage of integrating prior training over exclusive use of new data.

Neuroprostheses typically operate under supervised learning, in which a machine-learning algorithm is trained to correlate neural or myoelectric activity with an individual's motor intent. Due to the stochastic nature of neuromyoelectric signals, algorithm performance decays over time. This decay is accelerated when attempting to regress proportional control of multiple joints in parallel, compared with the more typical classification-based pattern recognition control.

Objectives: The association of contrast volume to the risk of contrast-related acute kidney injury (CR-AKI) appears to have resulted in a change in daily practice toward using lower contrast volume for all patients. Distal transradial access (dTRA) has advantages in terms of faster haemostasis and lower rates of proximal radial artery occlusion. The present study aimed to describe the authors' experience with the combination of ultra-low contrast (ULC) strategy and dTRA for routine coronary procedures in a real-world and broad population of all-comers patients.
