[On/off-pump beating coronary artery bypass grafting after thoracoplasty].

ABSTRACT

Off-pump coronary artery bypass grafting (CABG) [OPCAB] or on-pump beating CABG (conventional CABG) was performed in 3 post-thoracoplasty patients. Considering their poor respiratory function after thoracoplasty, OPCAB is considered more suitable than conventional CABG with cardio-pulmonary bypass in such cases with severe coronary lesions. However, because the sternum inclines or the pleural cavity may be polluted in these patients, special care is necessary for the operation. In such cases, it may be impossible to bypass to the circumflex artery in OPCAB, and is necessary to consider the use of percutaneous cardiopulmonary support (PCPS), cardio-pulmonary bypass or hybrid therapy before the operation.
