Literature article: an uncommon cause of myocardial ischemia after coronary artery bypass grafting: ¿the dangerous drainage¿.The authors presented patient with chief complaint of chest pain.The patient had a history of coronary artery bypass graft.The patient underwent cardiac catheterization which showed significant stenosis bypass to the right marginal artery and the native right coronary artery (rca).Coronary surgery where a venous bypass to the rca was performed.The patient showed signs of myocardial ischemia on serial electrocardiograms and supported with lab analyses of increased creatine kinase and troponin i.A postoperative cardiac catheterization was performed which showed that the silicon drain was putting pressure on the bypass, thereby impeding blood flow through the venous graft.The drain was immediately removed, and the bypass recovered its functionality.The author stated that myocardial ischemia and/or infarction occurring after cabg should prompt consideration of the possibility of mechanical compromise of a bypass graft by a drainage tube, even when soft silicone drains are used.
