Filter by:In the experimental setting inhibition of platelet activation was able to reduce immune-mediated necroinflammatory liver disease and consecutively hepatocellular carcinoma development. Therefore, antiplatelet therapy may not only have a preventive effect on hepatic artery patency but also on tumor recurrence. So far and to the best of our knowledge, no study investigated the effect of antiplatelet therapy on hepatic arterial patency, tumor recurrence and graft survival after primary liver transplantation.
In liver cirrhosis (LC),the activity of von Willebrand factor (vWF)-cleaving enzyme ADAMTS13 is reduced in LC patients and consequent progression of liver injury. Remarkably, it has been reported that a severe vWF/ADAMTS13 imbalance develops during liver transplantation (LT) and persists even after LT. Such changes are thought to contribute to postoperative thrombotic complications, which may lead to early adverse events of thrombotic microangiopathy after living-donor LT (LDLT). We investigated whether vWFPCR could predict EAD or graft failure following LT and compared it with FVIIIPCR, procoagulant, such as vWF and FVIII and anticoagulant, such as PC.
The aim of this study is to observe the efficacy and safety of lenvatinib in preventing recurrence of hepatocellular carcinoma patients with portal vein tumor thrombus after liver transplantation.
Researchers are trying to improve the understanding of systolic function of the heart at the time of liver reperfusion in patients undergoing orthotopic liver transplantation.
This is a multi-center prospective, observational study of the Quantra System with the QStat Cartridge in trauma patients and patients undergoing liver transplant.
Post-operative care following liver transplantation is characterized by a high incidence of infective and immunological complications. Restauration of liver function following liver transplantation is progressive and characterize a period of immuno-infective vulnerability. The purpose of this study is to characterize the early post-operative immune function in children after liver transplantation.
This is a pilot study designed to investigate the alterations in the gut microbiome that occur during the course of kidney transplantation, liver transplantation, allogeneic hematopoietic stem cells and mesenchymal stem cells transplantation in association with the clinical outcomes.
This study describes Cefazolin pharmacokinetics variation to target levels during liver transplantation.
Severe coagulopathy and operative bleeding are common in liver and multivisceral transplant recipients. This is related to reduced synthesis and function of clotting proteins in end-stage liver disease, thrombocytopaenia, thrombocytopathy, accelerated fibrinolysis, portal hypertension, inflammatory adhesions and intraoperative hemodilution. A pro-coagulant state is also a common finding in both groups, sometimes associated with fatal thromboembolism, and the balance between anti- and pro-coagulant effects is easily disrupted by intraoperative events. Use of point-of-care intraoperative viscoelastic testing, capable of discriminating between various potential causes of coagulopathy and of identifying some hypercoagulable states, is now routine in this setting. This has been shown to guide treatment faster and more reliably than standard laboratory screening tests. However, traditional viscoelastic tests based on a pin-and-cup arrangement are sensitive to technical error, movement and physical clot disruption, and the validity of measurements is highly dependent on operator training. A newer method (TEG® 6S) based on light reflection from a blood meniscus reduces scope for operator error but remains sensitive to movement. Measurement of ultrasonic resonance (or 'sonic estimation of elasticity via resonance [SEER] sonorheometry') using the Quantra® analyzer surgery appears to minimize these problems in studies performed in healthy volunteers, in spinal surgery and in both elective and urgent cardiac procedures. Pilot testing in the latter group suggests it may also differentiate qualitatively between fibrinogen and platelet deficiency, but the range of intrinsic coagulation disturbances in this context is limited. This study proposes to assess the validity of the Quantra® analyzer in a population with more extreme coagulopathy, including severe fibrinolysis, and recognized thrombophilic states.
Liver transplantation was historically associated with massive blood loss. Many factors have contributed to the decline in bleeding and transfusion in the past two decades including refinement of surgical techniques, anesthetics management and the use of point of care guided goal-directed hemostatic therapies. Increasing awareness of the adverse associations of allogenic transfusion has driven the quest for transfusion-free transplantation. Pre-operative management of preoperative anemia and targeted correction of coagulopathy is done to decrease blood transfusion. Liver transplantation is associated with the potential for massive operative blood loss, which has been recognized as one of the main causes of morbidity and mortality after liver transplantation. Therefore, a fine surgical procedure to reduce intraoperative hemorrhage is necessary for favorable outcomes of liver transplantation.
