Filter by:Obesity if a health endemic problem over the entire world. Bariatric surgery is the best chance for those patients with morbid obesity to loss weight and to maintain the loosed weight. Metabolic surgery is the new name for bariatric surgery like sleeve gastrectomy and gastric by pass due to the recognized changes in the homeostasis of the hormonal secretion responsive to the hunger status. After sleeve gastrectomy we observe many patients with thrombus of the portal vein system. This phenomena may be attributed to changes in the portal flow due to devascularization of the great curvature of the stomach. The aim of the study is to compare the portal flow by intra-operative Doppler ultrasound before and after surgery of the two procedures as sleeve gastrectomy and gastric bypass, were the vascularization is not changed by the surgery.
The purpose of this study is to determine the effect and safety of anticoagulation after endoscopic therapy in cirrhotic patients with portal vein thrombosis and to explore its effect on long-term rebleeding rate and mortality.
Anticoagulant therapy is generally recommended for all patients presenting with acute symptomatic splanchnic vein thrombosis, starting with either low-molecular weight heparin (LMWH) or unfractionated heparin and continuing with the vitamin K antagonists in most patients. Rivaroxaban is approved for the treatment of deep vein thrombosis and pulmonary embolism, but no studies have assessed the safety of rivaroxaban in the setting of splanchnic vein thrombosis. The investigators aim to collect prospective information on the safety of rivaroxaban in a pilot cohort of 100 patients with acute splanchnic vein thrombosis without liver cirrhosis.
This randomized phase III trial studies the side effects of and compares apixaban and dalteparin in reducing blood clots in patients with cancer-related venous thromboembolism. Venous thromboembolism is a condition in which a blood clot forms in a vein and then breaks off and moves through the bloodstream. Patients with cancer are at increased risk for venous thromboembolism. Apixaban and dalteparin are drugs used to prevent blood clots from forming or to treat blood clots that have formed. It is not yet known whether apixaban or dalteparin is more effective in reducing blood clots in patients with cancer related venous thromboembolism. ADAM-VTE
The purpose of this study is to determine the safety and efficacy of anticoagulation in the treatment of non-occlusive portal vein thrombosis in patients with liver cirrhosis.
portal vein thrombosis may be a negative prognostic marker of variceal bleeding in liver cirrhosis. Compared with conventional endoscopic and pharmacological therapy, transjugular intrahepatic portosystemic shunt may further improve the outcomes of portal vein thrombosis in liver cirrhosis with variceal bleeding.
To determine the effect and safety of anticoagulation after endoscopic therapy in cirrhotic patients with portal vein thrombosis and to explore whether it can decrease the short-term rebleeding rate.
Patients with portal vein thrombosis, who have chronic liver diseases especially liver cirrhosis associated with low levels of AT III, will receive intravenous injection of NPB-06 or placebo. The superiority of NPB-06 to placebo as anticoagulative agent will be verified in a randomized, double-blind, parallel-assignment design based on the proportion of patients obtained complete recanalization or partial recanalization of portal vein thrombosis. The safety of NPB-06 will be evaluated based on adverse events and adverse drug reactions (ADRs) observed between administration and 21 days after administration in comparison with the placebo group.
Several studies have confirmed that patients with cirrhosis possess an imbalance in procoagulant versus anticoagulant activity due to increased factor VIII and decreased protein C. Moreover, in the last two decades there has been an increased recognition that not only bleeding but also thrombosis complicates the clinical course of cirrhosis. The prevalence and pathogenesis of portal vein thrombosis (PVT) in patients with cirrhosis without hepatocellular carcinoma are not clearly defined. The Aim of this study is to assess the prevalence of portal vein thrombosis in patients with cirrhosis without hepatocellular carcinoma, and to prospectively assess the risk factors, outcome, and prognosis in these patients. The investigators plan to enroll two hundred patients with liver cirrhosis. The patients are going to follow up for one year and evaluate at baseline and every 6 months by liver function tests, coagulation test, upper abdomen ultrasound. All relevant clinical events will be evaluated at every follow up.
A retrospective study based on analysis of medical records of patients with hepatocellular carcinoma treated at the Hospital Sírio-Libanês (Sao Paulo-Brazil) between 2001 and 2011 with diagnosis confirmed by imaging or histological specimen underwent surgical resection with curative intent. The study aims to determine the prognostic value of vascular complications related to cancer and to evaluate the survival rate of these patients, comparing the data with those reported in the literature.
