Can the Left Internal Mammary Artery Be Used During Coronary Artery Bypass Graft Surgery in Patients Undergoing Bone Marrow Transplant? A First Case Report

Introduction: With the improvements in neoplasm treatments and the increased survival of patients with neoplastic diseases, we have entered a new era of having to deal with the complications of senile patients. The issue of bone fusion or the side effects of its delay, such as malunion or infections, are among the concerns for any surgery in patients whose bone marrow is affected by treatment or whose bone marrow blood flow is impaired. The left internal mammary artery (LIMA) is used for coronary artery bypass graft (CABG) surgery with its 2 - 3 times longer lifespan compared to saphenous vein grafts, but its harvest from the sternum affects the sternum blood flow and the outcome of its use is still not identified in patients undergoing bone marrow transplant. This case report is the first report on this issue. Case Presentation: A 60-year-old man with diffuse large B cell lymphoma who had undergone bone marrow transplant a year before had then developed chest pain, which was diagnosed as vessel disease; he was selected for CABG surgery. The LIMA was harvested during the surgery and the left anterior descending artery (LAD) was anastomosed. The saphenous vein graft was also anastomosed to the diagonal artery, obtuse marginatus (OM), posterior descending artery (PDA), and posterior left ventricle (PLV). After the surgery, the patient was followed up for six months, during which time no specific incidents occurred and no sternum-related complications were observed either. Conclusions: In this case report, the use of LIMA in a patient who had undergone a bone marrow transplant and CABG surgery was not associated with any increase in sternum-related complications.
