The radial artery: current concepts on its use in coronary artery revascularization

Area of Science:

• Cardiovascular Surgery
• Vascular Grafting
• Coronary Artery Bypass Grafting

Background:

• The radial artery (RA) is an alternative arterial conduit for coronary artery bypass grafting (CABG).
• Evidence suggests superior long-term patency of RA compared to saphenous vein grafts.
• Current utilization of RA in CABG remains suboptimal despite its benefits.

Purpose of the Study:

• To comprehensively review the current evidence on radial artery utilization in CABG.
• To provide guidance on optimal patient selection, harvesting techniques, and intraoperative strategies for RA conduits.
• To discuss methods for preventing graft spasm and improving outcomes in RA-based CABG.

Main Methods:

• Systematic review of randomized controlled trials and meta-analyses.
• Appraisal of evidence on RA outcomes, patient selection, and surgical techniques.
• Analysis of graft spasm prophylaxis and intraoperative management strategies.

Main Results:

• Radial artery grafts demonstrate superior long-term patency rates compared to saphenous vein grafts.
• Optimal harvesting and intraoperative management can mitigate risks associated with RA use.
• Evidence supports RA as a safe and effective conduit in selected CABG patients.

Conclusions:

• The radial artery is a valuable conduit for CABG, offering excellent long-term patency.
• Standardized techniques for harvesting and intraoperative management are crucial for maximizing RA graft success.
• Further research and adoption of RA may enhance overall CABG revascularization strategies.
