Background/Aim A reduction in portal vein inflow velocity seems to predispose to the emergence of portal vein thrombosis (PVT). Nonselective β-blockers (NSBBs), used to prevent variceal bleeding, may increase the development of PVT by reducing portal vein inflow velocity. In this retrospective case-control study, we evaluated the risk factors and clinical features of a first event of PVT in 130...

Portal vein thrombosis (PVT) is a frequent complication of liver cirrhosis and its prevalence increases with the severity of liver disease. Patients with liver cirrhosis and hepatocellular carcinoma may have either malignant or blunt (benign) PVT. In these patients, the diagnosis and characterization of PVT is important for the prognosis and further treatment. Ultrasound (US) is the modality of...

INTRODUCTION In recent years, there has been an increasing need for a reliable and practical tool for assessing fatigue-related impairment in the field. This study investigated the sensitivity of one potential tool, a 5-min version of the psychomotor vigilance task (PVT) specifically designed for use on personal digital assistants (PDA), to 28 h of sustained wakefulness. METHODS There were 15...

Portal vein thrombosis (PVT) is commonly classified into acute (symptom duration <60 days and absence of portal carvernoma and portal hypertension) and chronic types. However, the rationality of this classification has received little attention. In this study, 60 patients (40 men and 20 women) with PVT were examined using contrast-enhanced computed tomography (CT). The percentage of vein occlus...

Background: Cirrhotic patients have higher rates of hypercoagulable disorders. We hypothesized that orthotopic liver transplant (OLT) recipients with pre-operative portal vein thrombosis (PVT) have more postoperative thrombotic events than those without PVT. Aims: To compare rates of post-op thrombotic events and outcomes between those with and without pre-op PVT. Methods: All OLT recipients be...

BACKGROUND Portal vein thrombosis (PVT) is a rare but severe vascular disorder with an acute and a chronic course. Most patients have underlying liver cirrhosis; furthermore, thrombophilia is an important risk factor. However, idiopathic forms are also known. METHODS This review discusses nonsurgical treatment options in PVT. RESULTS AND CONCLUSION Therapy of acute PVT is based on anticoagu...

Background & Aims: Portal vein thrombosis (PVT) and Budd-Chiari syndrome (BCS) are two rare vascular disorders of the liver that can lead to life-threatening complications. We conducted a global survey to systematically analyze the scienti c publications in the elds of PVT and BCS. Methods: All papers regarding PVT and BCS were identi ed via the PubMed, EMBASE, and Cochrane library databases. e...

INTRODUCTION To identify the impact of portal vein thrombosis (PVT) and associated medical and surgical factors on outcomes post liver transplant (LT). MATERIAL AND METHODS Two analyses were performed. Analysis One: cohort study of 505 consecutive patients who underwent LT (Alberta) between 01/2002-12/2012. PVT was identified in 61 (14%) patients. Analysis Two: cohort study of 144 consecutive...

The paraventricular nucleus of the thalamus (PVT) is thought to regulate behavioral responses under emotionally arousing conditions. Reward-associated cues activate PVT neurons; however, the specific PVT efferents regulating reward seeking remain elusive. Using a cued sucrose-seeking task, we manipulated PVT activity under two emotionally distinct conditions: (1) when reward was available durin...
