Coronary artery bypass revascularization using bilateral internal thoracic arteries in diabetic patients: a...

Area of Science:

• Cardiovascular Surgery
• Diabetic Patient Management

Background:

• Coronary artery bypass graft (CABG) surgery is a common treatment for coronary artery disease.
• Diabetic patients often present with more complex coronary artery disease, posing unique surgical challenges.
• The use of bilateral internal thoracic arteries (BITA) in CABG is debated, especially in high-risk populations like diabetics.

Purpose of the Study:

• To evaluate the safety and efficacy of skeletonized bilateral internal thoracic artery grafting in diabetic patients undergoing CABG.
• To assess the impact of BITA grafting on sternal wound infection and early mortality in this cohort.
• To compare long-term and cardiac mortality between patients receiving BITA grafts versus other grafting strategies.

Main Methods:

• Retrospective analysis of diabetic patients who underwent CABG.
• Comparison of outcomes between patients receiving skeletonized BITA grafts and those receiving other arterial or venous grafts.
• Assessment of deep sternal wound infection, early mortality, remote mortality, and cardiac mortality.

Main Results:

• Skeletonized BITA grafting was not associated with an increased risk of deep sternal wound infection.
• No increased early mortality was observed in patients undergoing BITA grafting.
• Patients with BITA grafts experienced significantly lower remote mortality and cardiac mortality.

Conclusions:

• Coronary artery bypass graft surgery utilizing skeletonized bilateral internal thoracic artery grafts is a safe and effective strategy for diabetic patients.
• BITA grafting in diabetic patients leads to improved long-term survival and reduced cardiac mortality.
• This technique represents an excellent surgical option, challenging previous concerns about its application in diabetic populations.
