Insights
This case study shows that using the right internal mammary artery and both inferior epigastric arteries is a safe alternative for myocardial revascularization when other grafts fail. These vessels can be safely utilized for coronary artery bypass grafting.
Area of Science:
- Cardiovascular Surgery
- Vascular Grafting
Background:
- Coronary artery bypass grafting (CABG) is a common procedure for myocardial revascularization.
- Venous grafts, such as saphenous veins, are frequently used but are prone to occlusion.
- Internal mammary arteries and inferior epigastric arteries are alternative autologous vascular conduits.
Observation:
- A patient who previously underwent triple CABG using the left internal mammary artery and saphenous veins required reoperation due to venous graft occlusion.
- Limited availability of vascular substitutes necessitated the use of alternative arterial grafts.
Findings:
- The right internal mammary artery and both inferior epigastric arteries were successfully employed for myocardial revascularization.
- This surgical approach achieved successful revascularization in the absence of conventional graft options.
Implications:
- Bilateral internal mammary arteries and inferior epigastric arteries represent viable and safe options for arterial grafting in CABG.
- This case expands the armamentarium of vascular conduits for complex coronary revascularization procedures.
Abstract:
A patient having undergone triple coronary artery bypass grafting with the left internal mammary artery and both shorter saphenous veins was reoperated on because of occlusion of the venous grafts. As there was no other vascular substitute available, the right internal mammary artery and both inferior epigastric arteries were used to achieve myocardial revascularization. This case demonstrates that bilateral internal mammary arteries and inferior epigastric arteries can be used safely.
