Cholesterol crystal embolization (CCE) is a complication of atherosclerosis. A 67-year-old Japanese man underwent coronary artery bypass grafting. After the surgery, he underwent coronary angiography via the right femoral artery. Twelve days later, he suddenly developed acalculous cholecystitis and was treated with antibiotics. Gradual deterioration in renal function, purplish discoloration ...

Iatrogenic aortic dissection has been described, albeit infrequently, after coronary artery surgery performed under cardiopulmonary bypass. Since the advent of beating heart coronary surgery, several authors have described an apparent increase of this complication related to the application of a lateral clamp on the ascending aorta to perform the proximal ...

Extracorporeal support during cardiac surgery initiates an inflammatory response, causing damage to cardiac, pulmonary and renal tissue [Post Pump Syndrome (PPS)]. This is accompanied by a neutrophil leucocytosis and lymphopenia, but less is known about the role of monocytes and markers of monocyte activity. We studied 19 patients undergoing cardiac ...

The majority of patients undergoing coronary bypass surgery have at least one internal thoracic artery used as a conduit. Internal thoracic artery atherosclerosis is a rare but distal anastamotic stenosis or occlusion can occur often early after surgery. Percutaneous coronary intervention is a management option. A patient with a left ...
