Filter by:The purpose of this study is to evaluate the comparative effectiveness of nadroparin versus transjugular intrahepatic portosystemic shunt in cirrhotic patients with refractory asymptomatic portal vein thrombosis using a design of a multicenter, randomized controlled trial
The aim of this study is to identify incidence of portal vein thrombosis after umbilical catheter and to identify the risk factor of this condition ,location of PVT and prognosis of PVT.
Portal vein thrombosis (PVT) can lead to a further increase in portal venous pressure and increase the risk of rebleeding. Whether patients with acute esophagogastric variceal bleeding with occlusive PVT benefit from preemptive TIPS is still controversial. The present study is directed at comparing the outcome of patients with acute variceal bleeding with occlusive PVT treated by standard therapy (vasoactive drugs + endoscopic variceal ligation) with or without preemptive TIPS (performed during the first 1-3 days after endoscopic procedure). The primary outcome is survival free of variceal rebleeding at 6 weeks from inclusion.
The aim of study is to evaluate different etiological and risk factors that lead to chronic portal vein thrombosis and to delineate a management plan for chronic portal vein thrombosis in children.
The goal of this multicenter retrospective cohort study is to investigate the clinical outcomes and prognostic factors after hepatic resection in patients with HCC exhibiting PVTT, and to develop a prognostic index that can be helpful in determining the treatment strategy.
This study is the first to compare the efficacy and safety of recombinant human adenovirus type 5 injection via hepatic artery infusion combined with TACE-based combination therapy for the treatment of patients with stage IIIa primary hepatocellular carcinoma with portal vein carcinoma thrombosis, providing a safe and reliable treatment method for the clinical treatment of this group of patients, and also providing a reference and basis for the treatment of other tumors with this new treatment model.
Patients with clinically significant portal hypertension allocated to implantation of a transjugular intrahepatic portosystemic shunt (TIPS) at the Department of Medicine II of the University Medical Center Freiburg, Germany will be offered to participate in this prospective observational trial. Clinical and laboratory as well as outcome parameters will be assessed before and within the first 12 months after TIPS implantation following a regular follow-up schedule with clinical visits at the University Medical Center Freiburg. During follow-up visits, serum/plasma samples and peripheral blood mononuclear cells (PBMC) are collected and stored in a associated biobank.
This study is investigator initiated, single-institution, prospective, phase 2 open-label study to determine the efficacy and safety of combination therapy of atezolizumab/bevacizumab and proton beam therapy to portal vein tumor thrombosis with or without main primary tumor in patients with stage 3 or higher hepatocellular carcinoma (HCC) with Vp2-4 portal vein invasion who had not undergone systemic therapy for HCC. The primary endpoint of this study is progression-free survival and secondary endpoints are overall survival (OS), time to progression (TTP), objective response rate, disease control rate (DCR), and time to local disease progression (LTP).
Immunothrombosis has recently been used to describe the responses/mechanisms in thrombosis. Systemic inflammatory markers are prognostic markers for a variety of thrombotic conditions; however, their potential value in predicting portal vein thrombosis (PVT) is unknown. This study aimed to establish an easy-to-use nomogram based on systemic inflammatory markers to predict portal vein thrombosis (PVT) in patients with liver cirrhosis.
In case of acute portal vein thrombosis (PVT) prothrombotic factors are identified in about 60% of cases, while a local condition is present in 30% of cases. Prothrombotic factors may indicate a long term anticoagulant therapy whereas the risk of recurrence seems low when a local condition is isolated (cholecystitis, angiocholitis, liver abces, diverticulitis, appendicitis, acute/chronic pancreatitis, chronic bowel inflammatory disease, acute hepatitis due to cytomegalovirus, bacteroïdes pylephlebitis, abdominal neoplasia such as adenocarcinoma of the colon, abdominal traumatism or surgery such as cholecystectomy, bariatric surgery or splenectomy). To date the impact of prothrombotic factors associated with local conditions responsible for acute PVT has not been well studied except for acute or chronic pancreatitis. No significant association has been pointed out in this pathology. The aim is to determine what are the risk factors of thrombotic recurrence or extension associated with local conditions responsible for acute non cirrhotic PVT, and to evaluate the rate of secondary long term anticoagulant therapy.
