Complete arterial revascularization in the diabetic patient--early postoperative results

Area of Science:

• Cardiovascular Surgery
• Diabetic Patient Management
• Arterial Grafting Techniques

Background:

• Arterial grafts offer prognostic benefits for diabetic patients undergoing coronary artery bypass grafting (CABG).
• Graft availability and sternal complications have limited the use of arterial grafts in diabetic patients.
• Complete arterial coronary artery bypass grafting (caCABG) with skeletonized grafts, radial arteries (RA), and T-graft approach may reduce perioperative risks in diabetic patients.

Purpose of the Study:

• To evaluate the safety and efficacy of caCABG in diabetic patients compared to non-diabetic patients.
• To assess the utility of skeletonized arterial grafts, RA, and T-graft approach in diabetic patients.
• To determine if caCABG in diabetic patients yields comparable outcomes to non-diabetic patients.

Main Methods:

• Retrospective analysis of perioperative data from 174 diabetic and 402 non-diabetic patients who underwent caCABG.
• Graft utilization included bilateral internal thoracic arteries (ITA) or ITA and RA.
• Comparison of patient characteristics, including incidence of 3-vessel disease and left ventricular ejection fraction.

Main Results:

• No significant differences in the need for intra-aortic balloon pump, myocardial infarction, or sternal complications between diabetic and non-diabetic groups.
• In-hospital mortality rates were comparable: 1.7% for diabetic patients versus 2.2% for non-diabetic patients.
• Diabetic patients showed a higher incidence of 3-vessel disease and lower left ventricular ejection fraction.

Conclusions:

• caCABG using skeletonized arterial grafts and the T-graft approach is as safe in diabetic patients as in non-diabetic patients.
• The use of RA as a second graft obviates the need for bilateral ITA harvesting.
• This approach offers a viable and safe revascularization strategy for diabetic patients with coronary artery disease.
