The radial artery as a bypass graft

Area of Science:

• Cardiovascular Surgery
• Vascular Grafts

Background:

• The radial artery is being re-evaluated for use as an arterial graft in coronary artery bypass grafting (CABG).
• Its ready availability and safe harvesting with adequate collateral circulation make it a promising alternative.
• Concerns regarding subclinical atheroma require careful consideration.

Purpose of the Study:

• To assess the feasibility and early outcomes of using the radial artery as an arterial graft in CABG.
• To evaluate the safety and efficacy of radial artery harvesting techniques.
• To explore the potential benefits, including cost savings and early patient discharge.

Main Methods:

• Radial artery harvesting using a "minimal touch" technique with vasodilators to prevent vasospasm and occlusion.
• Graft configuration options include single, "Y"-anastomosed with internal mammary artery, or sequential grafting.
• Evaluation of early mortality and complication rates.

Main Results:

• Early mortality and complication rates associated with radial artery grafting are low.
• The technique minimizes the need for leg incisions, potentially leading to cost savings and earlier patient discharge.
• Early results demonstrate encouraging outcomes for radial artery grafts.

Conclusions:

• Radial artery grafting is a safe and effective option for CABG with promising early results.
• Further long-term follow-up is necessary to establish late patency rates and impact on patient survival.
• This approach offers potential advantages in terms of resource utilization and patient recovery.
