Emergency coronary artery bypass grafting after substernal gastric tube interposition for esophageal cancer.
A 67-year-old man who had undergone substernal gastric tube interposition due to esophageal cancer showed ST changes on electrocardiography. Diagnosis was severe stenosis of the left anterior descending branch that required emergency coronary artery bypass grafting. Preoperative computed tomography (CT) showed the feeding arteries of the gastric tube were in contact with the left internal mammary artery. Therefore, we felt harvesting this artery could be dangerous and decided to perform a median sternotomy, approaching from the right side of the gastric tube. The pericardium was easily and safely reached. We undertook on-pump cardiac arrest single coronary artery bypass grafting of the left anterior descending artery with a saphenous vein graft. The postoperative course was uneventful without mediastinitis. Cardiac surgery after esophageal cancer is often performed from a left thoracotomy. But, we recommend a median sternotomy be performed as an option. Preoperative contrast-enhanced CT should be considered as it may indicate the need for a significant revision such as a median sternotomy.
