OBJECTIVE We determined whether minimally invasive direct coronary artery bypass (MIDCAB) leads to excellent postoperative pulmonary function, and which contributes more to this--minithoracotomy or avoidance of cardiopulmonary bypass. METHODS Pulmonary function 1 week before and 2 weeks after surgery was evaluated in 8 patients undergoing MIDCAB (Group(More)
In coronary insufficiency produced by Kawasaki disease, myocardial revascularization using saphenous vein, internal mammary arteries, and a combination of both grafts has been performed with considerable success. Recently, we successfully used a right gastroepiploic artery as another conduit in coronary revascularization of a 6-year-old boy with Kawasaki(More)
A metastatic ball tumor in the right atrium originating from esophageal cancer is extremely rare. A 53-year-old woman had two such tumors without any other types of metastasis. These tumors were associated with severe thrombocytopenia caused by the consumption of platelets. Even after repeated transfusions of platelets and fresh frozen plasma, the(More)
We investigated sources of bacterial contamination of intraoperative salvaged blood producted by autologous transfusions device (CS; CELL SAVER 5, Heamonetics Corp., Braintree, MA). Eleven patients undergone open heart surgeries including 2 emergency operations with a median sternotomy enrolled in this study. Blood samples were drawn from salvaged blood(More)
In cardiac surgery, several studies have shown bacterial contamination rates of intraoperative salvaged blood ranging from 12.7 to 96.8%. We evaluated the relation between intraoperative salvaged blood transfusion produced by the Cell Saver 5 device (Haemonetics Corp., Braintree, MA, USA) and postoperative infection determined by bacteriological study and(More)
In this prospective study, we evaluated contamination of surgical fields in open heart operations by salvaged blood culture used in autologous transfusions device (Cell Saver 5, Heamonetics Corp., Braintree, MA, USA). And also, we prospectively investigated an efficacy of pre- and intra-operative prophylactic antibiotics administrations (cefazolin). Thirty(More)
BACKGROUND Clinical outcomes and problems following off-pump coronary artery bypass grafting (OPCAB) in elderly patients have not been clarified. METHODS AND RESULTS The surgical results of elderly patients aged 75 years or older (n=50; 38 males, mean age, 78.8 years) were reviewed and compared with those of younger patients (n=95; 79 males, mean age,(More)
We treated a 53-year-old man who had a dorsal pancreatic aneurysm and three pancreaticoduodenal aneurysms with celiac obstruction. Resection of the dorsal pancreatic aneurysm and bypass grafting from abdominal aorta to common hepatic artery with his saphenous vein were performed. A diagnosis of the aneurysm caused by arteriosclerotic changes was confirmed(More)
