Redo-coronary artery bypass grafting( redo-CABG) still remains a challenging operation and is associated with a significantly higher risk of morbidity and mortality when compared with primary CABG. The higher risk of redo-CABG is largely attributable to the increased technical difficulty and the greater incremental risk in redo-CABG patients. Annual reports by the Japanese Association for Thoracic Surgery in recent years reveled that the absolute and relative number of redo-CABG gradually decreased, and in-hospital mortality did not change significantly over this periods and was much higher than primary CABG. The increasing use of percutaneous coronary intervention (PCI) for previous CABG patients could be a reason for the decrease of redo-CABG, and therefore surgery of redo-CABG is becoming more limited. This paper presents the current indications, safe surgical technique, and perioperative management of redo-CABG patients, as well as the contemporary results of redo-CABG in our institution.

Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Abdominal artery that follows the curvature of the stomach. The right gastroepiploic artery is frequently used in CORONARY ARTERY BYPASS GRAFTING; MYOCARDIAL REVASCULARIZATION, and other vascular reconstruction.
Coronary artery bypass surgery on a beating HEART without a CARDIOPULMONARY BYPASS (diverting the flow of blood from the heart and lungs through an oxygenator).
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Inferior and external epigastric arteries arise from external iliac; superficial from femoral; superior from internal thoracic. They supply the abdominal muscles, diaphragm, iliac region, and groin. The inferior epigastric artery is used in coronary artery bypass grafting and myocardial revascularization.
