AI Article Synopsis
- Directional coronary atherectomy (DCA) is a method to remove plaque from coronary arteries, but it typically requires an 8Fr guiding catheter, which poses certain limitations.
- The study explored using a transradial approach (TRA) to perform DCA with an 8Fr sheathless guiding catheter, which can be inserted if a 6Fr sheath fits easily.
- In five successful cases, this new approach proved effective and not uncomfortable for patients, potentially reducing bleeding complications during the procedure.
Article Abstract
Background: Directional coronary atherectomy (DCA) revived in Japan since 2014. DCA is a special device to remove the atherosclerotic plaque of coronary artery in percutaneous coronary intervention (PCI). However, DCA procedure is recommended to perform by 8Fr system, which is one of the limitations of DCA.
Case Series: Since transradial approach is the main access route for PCI, we considered how to perform DCA by TRA. The external diameter of 8Fr guiding catheter (GC) and 6Fr sheath are 2.70 and 2.67 mm. Then, if 6Fr sheath can be inserted without any resistance, 8Fr GC is considered to be insertable. We performed 5 cases of DCA by the transradial 8Fr sheathless GC approach, all cases were successful without discomfort associated with insertion and removal of the 8Fr GC.
Conclusion: DCA by the transradial 8Fr sheathless GC approach might be one of options to avoid bleeding complication and serve more comfortable treatment for the patients.

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

Herein, we report a case of carotid artery stenting with proximal flow protection for severe stenosis of the left internal carotid artery using transbrachial and transradial artery approaches. Because an abdominal aortic aneurysm was present, we avoided the transfemoral approach. The procedure was successfully performed with a combination of an 8-Fr balloon guide catheter and microballoon catheter on separate axes.

Article Synopsis
- The study explores the use of transradial access (TRA) with a balloon guide catheter (BGC) for carotid artery angioplasty and stenting, as this method hasn't been extensively researched before.
- Researchers analyzed a database of patients who underwent this procedure from January 2021 to June 2022, focusing on demographics, complications, and conversion rates.
- The findings indicate that using the Walrus BGC through an 8-Fr sheath for carotid stenting is both safe and effective, with very few complications and a low need for conversion to femoral access.

Effectiveness and Safety of the Transradial 8Fr Sheathless Approach for Revascularization of Chronic Total Occlusions.

The experience with the transradial approach in percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) in the United States is limited. We looked at the safety and feasibility of a home-made sheathless transradial technique (STT) with regular 8Fr catheters in CTO PCI. In March 2013, we developed an 8Fr STT for CTO PCI.
