BACKGROUND The use of endoscopic saphenous vein harvesting (ESVH) for coronary artery bypass grafting (CABG) is growing. This study was done to investigate the extent of endothelial injury in ESVH compared with that of the standard open method (OSVH), and under various physical and chemical preservation factors. METHODS We endoscopically removed the… (More)
OBJECTIVE The development of a thoracoscopically assisted technique to be performed with the patient under local anesthesia for both diagnostic and therapeutic purposes when treating pleural effusions and empyemas in high-risk surgical patients. METHODS Twenty patients with pleural effusion or empyema who were also determined to be at high risk for… (More)
OBJECTIVE Interleukin-10 (IL-10) is an anti-inflammatory cytokine that suppresses lymphocyte functions, regulates production of proinflammatory cytokines, and suppresses nitric oxide production by activated macrophages. We examined IL-10 expression and its value as a surrogate index for nitric oxide (NO) production in endothelial cultures obtained from… (More)
Preservation of myocardial high-energy phosphates correlates with the heart's ability to resume normal function following aortic crossclamping (AXC). The ability of the canine myocardium to synthesize and maintain ATP during 180 minutes of AXC was evaluated in 12 hearts subjected to either blood or crystalloid cardioplegic arrest. Group 1 hearts were… (More)
Background: Gamma interferon (IFN-γ) is produced by activated natural killer and T cells under pathologic circumstances. The objective of our study was to compare the level of IFN-γ in open and endoscopic methods of vein harvesting for coronary artery bypass surgery (CABG).
