[Emergency coronary artery bypass grafting for acute myocardial infarction presenting as cardio-pulmonary arrest during a marathon race; report of a case].

We report a case of coronary artery bypass grafting for acute myocardial infarction which presented as cardio-pulmonary arrest during a marathon race. A 57-year-old man collapsed at the 18-km point in the Toyohashi half marathon. He was treated with an automated electrical defibrillator( AED) for ventricular fibrillation in an ambulance.

[Double-patch technique through right ventriculotomy for residual shunt after infarct exclusion technique for post-infarction ventricular septal perforation].

We report a case in which the double-patch technique was used to repair residual shunt after infarct exclusion technique for post-infarction ventricular septal perforation (VSP). A 68-year-old man was diagnosed with post-infarction VSP and surgical interveniton was performed by infarct exclusion technique through left ventriculotomy. Residual shunt was observed by left ventriculography, and he developed cardiac failure in spite of medical therapy.

Intramucosal PCO2 measurement as a new monitoring method of free jejunal transfer following pharyngo-laryngo-esophagectomy.

The choices for practical monitoring of free jejunal transfer have been quite limited because of its own characteristics, such as buried form, lack of skin surface, and the structure of a hollow viscous tract. Physiologically, it is known that tissue hypoxia caused by compromised perfusion leads to an increase of partial pressure of carbon dioxide (PCO2). Because of its physiological properties, the diffusion of carbon dioxide is always equilibrated between the mucosa of a hollow viscous organ and its lumen.
