Post-pneumonectomy coronary artery bypass graft surgery.
BMJ case reports(2024)
Abstract
Postpneumonectomy changes, including ipsilateral diaphragmatic elevation and rib crowding, mediastinal shifting of the heart and reduction of respiratory functional reserve by 45%-55%, make cardiac surgery challenging in terms of access to the heart and great vessels. There is a paucity of literature on coronary artery bypass graft (CABG) surgery in patients with a history of pneumonectomy. We report a case of a male in his 70s with a history of left pneumonectomy who underwent a successful on-pump CABG surgery using the left internal mammary artery graft and great saphenous vein graft. The patient was extubated postoperatively and discharged in a stable condition. With no consensus available for optimal preoperative, intraoperative and postoperative management for these high-risk patients, our case report adds to the rare literature regarding successful on-pump CABG after pneumonectomy.
