Background: Little information exists regarding mid-term and long-term patency of radial artery grafts.
Methods And Results: We performed restudy coronary angiography at 5.2+/-0.4 years after surgery on 50 asymptomatic patients who had undergone coronary artery bypass graft surgery, using at least 1 radial artery graft, to determine both graft patency and presence of narrowing. We examined preoperative clinical or angiographic variables that might predict graft occlusion. Radial artery graft patency was 89%, with 91% of grafts free of narrowing. Preoperative New York Heart Association anginal class < or =2, target vessel proximal stenosis < or =70%, and small target vessel supply territory were predictive of graft occlusion.
Conclusions: At 5 years after surgery, radial artery grafts have disease-free patency rates that are similar to other graft types.

The comparative efficacy and safety of Tiger II versus judkins catheters in coronary angiogram via the radial artery access: a meta-analysis.

Background: Trans-radial coronary angiogram (TR-CAG) has gained popularity due to lower complication rates compared to transfemoral access. Operators can use either conventional catheters, such as Judkins, or single dedicated catheters, such as Tiger-II. This meta-analysis compared the safety and efficacy of Tiger-II versus Judkins catheters in TR-CAG.

Endovascular treatment (EVT) for patients with lower extremity artery disease is widely used as a less invasive alternative to surgical bypass. Recently, transradial artery intervention has gained popularity owing to its minimally invasive nature. The distance from the radial artery to the target vessel is critical for success; however, effective pre-assessment methods have not yet been established.

Background: We aim to share our experience of transradial access (TRA) for cerebral angiography and intervention in five patients ranging from 6 days to 7 months of age.
Methods: In this institutional review board-approved, retrospective case series, we reviewed all patients who underwent TRA for cerebral angiography with and without intervention. We describe three techniques for radial artery cannulation, namely: (1) bareback; (2) with a micropuncture sheath; and (3) with an intravenous catheter.
Feasibility and Safety of Distal Radial Artery Access with Recanalization of a Chronic Radial Artery Occlusion for Subsequent Coronary Angiography and Intervention.
Acta Cardiol Sin

Department of Internal Medicine, Division of Cardiology, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University College of Medicine, Kaohsiung, Taiwan.
Aims: This study aims to verify the feasibility and safety of percutaneous coronary intervention (PCI) after a distal transradial approach (dTRA) with radial artery occlusion (RAO) recanalization.
Methods: Between July 2018 and January 2022, 30 patients underwent PCI following attempted RAO recanalization via dTRA. Among these cases, the target radial arteries could not be recanalized in five patients, necessitating alternative vascular access.
The Effects of Local Heating on Facilitating Radial Angiography: A Randomized Controlled Trial.

Article Synopsis
- The study explores how local forearm heating can improve the radial angiography process by making it quicker and more efficient for patients and healthcare professionals.
- The clinical trial involved 80 patients, comparing outcomes between those who received infrared heating before the procedure and those who did not.
- Results showed that patients who were heated experienced fewer complications and shorter procedure times, suggesting that using local heat can enhance patient comfort and the overall angiography process.
