background: lactic acidosis in cardiac surgical patients is a manifestation of systemic inflammation and excess pro-inflammatory cytokine production. this investigation was designed to integrate basic concepts about lactate acidosis with a clinically used of serum lactate in patients under coronary artery bypass surgery (cabg) by on pump method. methods: from august to september 2012, 15 patien...

BACKGROUND The positive impact of Roux-en-Y gastric bypass on weight, comorbidities, and health-related quality of life is well documented. However, 50 percent of patients regain some of the lost weight after 2 years with Roux-en-Y gastric bypass and present a mean weight regain of 10 to 15 percent after several years, partially losing the previously obtained benefits. The authors hypothesize t...

introduction aortic surgery has made much progress recently. yet the combination of aortic surgery and coronary artery bypass grafting has remained a major issue for the surgeons. patient and observation herein, we present a case of severe aortic insufficiency with aortic aneurysm concomitant with single coronary artery disease on the right coronary artery. the patient underwent bentall procedu...

A review of 122 patients treated for pancreatic adenocarcinoma from January 1978 through December 1984 was accomplished to determine patient survival and the effect of surgical palliation. One hundred patients underwent laparotomy, including biopsy only (n = 42), biliary bypass (n = 30), gastric bypass (n = 1), biliary and gastric bypass (n = 14), and curative resection (n = 13). Total patient ...

BACKGROUND & AIMS Mechanisms underlying weight loss maintenance after gastric bypass are poorly understood. Our aim was to examine the effects of gastric bypass on energy expenditure in rats. METHODS Thirty diet-induced obese male Wistar rats underwent either gastric bypass (n = 14), sham-operation ad libitum fed (n = 8), or sham-operation body weight-matched (n = 8). Energy expenditure was m...

Register bypass provides additional datapaths to eliminate data hazards in processor pipelines. The difficulty with register bypass is that the cost of the bypass network is substantial and grows substantially as processor width or pipeline depth are increased. For a single application, many of the bypass paths have extremely low utilization. Thus, there is an important opportunity in the desig...

An extracorporeal bypass was performed in mongrel dogs for 2 hours with or without hypertonic mannitol infusions. In animals given mannitol, the plasma osmolality was elevated maximally to 344 +/- 7.1 mOsm/L and the urine volume was maintained well during bypass. A hypertonic mannitol solution was effective in maintaining the CPAH during and after bypass, but was not effective in minimizing the...

introduction: anxiety and depression are among major problems encountered by most patients after cardiac surgery. they can have serious consequences for patients’ quality of life, physical and psychological morbidity, and follow-up treatments. accordingly, the present study was conducted to determine the status of depression and the associated factors in coronary artery bypass grafting (cabg) p...

a 73-year-old woman who had undergone coronary artery bypass grafting for coronary artery stenosis six years ago, presented with right lower extremity claudication. angiography revealed right external artery stenosis. elective external iliac ptca was performed complicated with simultaneous external iliac artery and vein rupture that was an exceedingly rare event. retroperitoneal laparotomy with...

conclusions to our knowledge, this is the first case of ctc that was identified incidentally in the retrocaval position and caused intermittent obstruction of vena cava. case presentation the present study reports on a 66-year-old female with coronary artery disease (cad) who was scheduled for coronary artery bypass grafting (cabg) at our hospital. during mediastinal exploration and pericardiot...
