The relation among glutathione-related enzyme activities, thiobarbituric acid-reactive substances of the human aorta and internal mammary artery, and serum lipids was studied in 40 male patients undergoing coronary revascularization. Glutathione peroxidase and glutathione reductase activities were significantly higher in the internal mammary artery, whereas glutathione transferase activity was ...
OBJECTIVE The aim of this study was to analyse the arterial wall mechanics and the vasoreactive properties of the radial artery in comparison with those of the internal mammary artery and to discuss their implications for coronary bypass grafts. METHODS Measurements of pressure and diameter were obtained from cylindrical segments, whereas measurements of reactivity were obtained from ring seg...
OBJECTIVE We developed a thoracoscopic internal mammary artery harvest technique using an ultrasonic scalpel, the Harmonic Scalpel (Ethicon Endo-Surgery, Cincinnati, OH). This is the first report of 9 month follow-up using this technique. METHODS The Harmonic Scalpel is activated ultrasonically by vibrating at 55000 Hz. Compared with electrocautery, lower heat (<100 degrees C) and less smoke ...
BILATERAL ligation of the internal mammary arteries was proposed by Fieschi as a simple surgical means of treating patients with coronary artery disease. The procedure aims to increase the blood pressure in the pericardiophrenic branches of the internal mammary arteries and, thereby enhancing coronary anastomoses to the myocardium. Observations made on patients have been conflicting,' as have t...
