Axillary-coronary artery bypass reconstruction as an alternative in coronary artery reoperations.

Abstract

Background and aims: The increasing incidence of reoperations in coronary surgery associated with higher perioperative risks is a challenge for refinement of the surgical methods. The aim of the work is to prove the feasibility and satisfactory intermediate results of minimally invasive axillary-coronary artery bypass reconstruction in redo coronary surgery in case the left internal mammary artery had already been harvested.

Material and methods: Three patients (six months, two and six years after primary coronary artery bypass grafting) admitted for redo coronary surgery because of a recurrence of angina and proven malfunction of the left internal mammary artery-left anterior descending coronary artery anastomosis. An axillary-coronary venous graft was performed via left anterior small thoracotomy (LAST) on a beating heart in all three cases.

Results: Excellent patency of the graft was noted on control angiography within 9 days after the procedure together with good clinical improvement in midterm follow-up.

Conclusion: Minimally invasive axillary-coronary artery bypass via LAST access in redo coronary surgery is a good alternative in cases where the left internal mammary artery cannot be used.
