How to use the left internal thoracic artery which has been damaged during harvesting?

Area of Science:

• Cardiovascular Surgery
• Vascular Grafting
• Coronary Artery Bypass Grafting

Background:

• The internal thoracic artery is the preferred conduit for coronary artery bypass grafting due to its superior patency rates.
• Damage to the internal thoracic artery during surgical harvesting is a known complication, often resulting in the conduit being discarded.

Observation:

• A novel surgical approach is presented to utilize the distally intact portion of a proximally damaged left internal thoracic artery.
• This technique involves reversing the conduit and utilizing its retrograde blood supply from the superior epigastric and musculophrenic arteries.

Findings:

• The modified internal thoracic artery segment was successfully used as an in situ arterial conduit.
• This allowed for revascularization of the left anterior descending coronary artery despite proximal damage to the conduit.

Implications:

• This approach offers a method to salvage valuable arterial conduits that would otherwise be discarded.
• It may increase the availability of suitable grafts for coronary artery bypass procedures, potentially improving outcomes for patients.
