Liver ischemia/reperfusion injury has been extensively studied during the last decades and has been implicated in the pathophysiology of many clinical entities following hepatic surgery and transplantation. Apart from its pivotal role in the pathogenesis of the organ's post reperfusion injury, it has also been proposed as an underlying mechanism responsible(More)
In split-liver transplantation, the entire portal flow is redirected through relatively small-for-size grafts. It has been postulated that excessive portal blood flow leads to graft injury. In order to elucidate the mechanisms of this injury, we studied the hemodynamic interactions between portal vein- and hepatic artery flow in an experimental model in(More)
BACKGROUND Blood loss during liver resection constitutes the primary determinant of the postoperative outcome. Various techniques of vascular control and maintenance of a low central vein pressure (CVP) have been used in order to prevent intraoperative blood loss and postoperative complications. Our study aims at assessing the effects of different levels of(More)
BACKGROUND The aim of this study was to compare ischemic preconditioning with the intermittent vascular occlusion technique in liver resections performed under inflow and outflow occlusion. METHODS Fifty-four patients with resectable liver tumors assigned were randomly to undergo surgery with either ischemic preconditioning (IP group, n = 27) or with(More)
PURPOSE Severe pulmonary hypertension (PH) is a major cause of right ventricular (RV) dysfunction. Various iv vasodilator modalities have been used with limited results because of lack of pulmonary selectivity. The aim of the present controlled study was to evaluate the efficacy of inhaled iloprost, a synthetic prostacyclin analogue, in patients with(More)
Liver resections are frequently associated with significant ischemia-reperfusion (I-R) injury of the liver remnant. The aim of this study was to investigate whether deferoxamine (DFO) can ameliorate I-R injury during major hepatectomies performed under vascular exclusion of the liver in a porcine model. Twelve female domestic pigs were divided into control(More)
PURPOSE Idiopathic intracranial hypertension (IIH) is a rare condition characterized by raised intracranial pressure (ICP) without related pathology in either the brain or the composition of cerebrospinal fluid (CSF). Herein, we provide a brief review of the clinical presentation of IIH and the anesthetic considerations in parturients diagnosed with the(More)
E ach year, .16,000 patients receive whole organ transplants in the United States alone, and this number is expected to increase yearly (1). Because the 1-yr survival rate for most transplant recipients is approaching 80%–90% and continues to improve annually, an increasing number of patients who received a transplant present for either elective or(More)
OBJECTIVE Pain is one of the most undertreated medical complaints, with barriers to effective pain management lying in poor education of health professionals and misconceptions regarding patients in pain. The aim of this study was to assess whether an elective undergraduate course on chronic pain offered in Greek medical schools influences knowledge and(More)
BACKGROUND Experimental findings have demonstrated a beneficial role of retrograde blood flow from hepatic veins that takes place during the Pringle maneuver in liver resections. The cytoprotective effect of hepatovenous back-perfusion has not been evaluated in humans. A randomized prospective study was designed to compare the response of liver cells to(More)
