Predicting severe multivessel coronary artery disease to guide access strategy in patients undergoing invasive coronary angiography.
Coron Artery Dis
December 2024
Department of Cardiology, Austin Health.
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.
Clinical Outcomes of Shifting from Transfemoral-First to Transradial-First Approach in Carotid Artery Stenting: A Retrospective Two-Timeframe Comparison at a Single Center.

Carotid artery stenting (CAS) has traditionally been performed using the transfemoral approach (TFA). Recently, the transradial approach (TRA) has gained attention for its lower invasiveness and reduced complication risk. This study compares outcomes between two access strategy timeframes, TFA-first and TRA-first, to evaluate how this shift influences outcomes in a real-world setting.

Objectives: This study evaluates the feasibility, safety, and efficiency of using a balloon guide catheter (BGC) through transradial access (TRA) for mechanical thrombectomy (MT) in patients with anterior circulation strokes.
Methods: A retrospective case series of patients who underwent MT using BGC through TRA for acute ischemic stroke in the anterior circulation was conducted. Data collected included procedural times (from puncture to revascularization), technical success, complication rates, and clinical outcomes.
Feasibility and Safety of the Distal Transradial Access for Noncardiac Intervention.
Interv Radiol (Higashimatsuyama)
November 2024
Department of Diagnostic Radiology and Radiation Oncology, Chiba University Graduate School of Medicine, Japan.
Purpose: Distal transradial access through the anatomical snuffbox has been highlighted in recent research because it provides extremely low invasiveness. It has demonstrated its feasibility and safety for cardiac intervention. However, its characteristics for noncardiac intervention are not well known.

Article Synopsis
- Distal transradial access (dTRA) through the anatomical snuffbox offers benefits for endovascular treatments but faces challenges due to the small diameter of the radial artery affecting the use of balloon-guide catheters (BGCs).
- A study involving 170 patients treated with sheathless dTRA using an 8Fr Optimo BGC found a radial artery occlusion (RAO) rate of 28%, with a significant correlation between smaller artery diameter and higher RAO risk.
- The research suggests a threshold of 2.4 mm for radial artery diameter to predict RAO risk, indicating that careful evaluation of artery size is essential for choosing large-bore BGCs; further studies are needed for validation and
