Common hepatic artery as an inflow site for off-pump coronary artery bypass grafting

Area of Science:

• Cardiovascular Surgery
• Vascular Biology
• Surgical Innovation

Background:

• Coronary artery bypass grafting (CABG) is a critical intervention for ischemic heart disease.
• Identifying suitable inflow vessels is crucial for successful CABG, especially in off-pump procedures.
• The ascending aorta and gastroepiploic artery are common inflow sites, but alternatives are sometimes necessary.

Purpose of the Study:

• To evaluate the common hepatic artery (CHA) as an alternative inflow site for coronary artery bypass grafting.
• To assess the feasibility and efficacy of using the CHA for saphenous vein graft bypass to the right coronary system.
• To determine if the CHA can provide adequate blood flow and a short bypass distance when standard inflow sites are compromised.

Main Methods:

• Off-pump coronary artery bypass grafting (OPCAB) was performed.
• The common hepatic artery (CHA) was utilized as the inflow vessel.
• A saphenous vein graft was anastomosed from the CHA to the right coronary artery system.

Main Results:

• The common hepatic artery (CHA) demonstrated sufficient blood flow for a saphenous vein graft bypass.
• A short-distance bypass to the right coronary system was achieved using the CHA.
• The CHA proved to be a suitable alternative inflow site when the ascending aorta and gastroepiploic artery were deemed inadequate.

Conclusions:

• The common hepatic artery (CHA) is a feasible and effective inflow option for coronary artery bypass grafting.
• CHA inflow can ensure adequate perfusion and facilitate short bypass grafts in complex surgical scenarios.
• This approach expands the options for inflow vessel selection in off-pump coronary artery bypass grafting, enhancing surgical versatility.
