OBJECTIVE: The hypothesis of this study is that human subchondral bone exhibits abnormal patterns of perfusion in osteoarthritis (OA) that can be characterized by kinetic parameters of blood flow using dynamic contrast enhanced (DCE) MRI. DESIGN: Fifteen subjects with advanced OA of the knee and 7 control subjects without OA were studied at 1.5 Tesla with DCE-MRI. Region of interest (ROIs) analysis of pharmacokinetic perfusion parameters were used to examine initial uptake and washout of the contrast agent in the lateral tibial plateau...

INTRODUCTION: Phlegmasia cerulea dolens (PCD) is a rare complication of deep venous thrombosis (DVT). Massive ileo-femoral DVT is usually the cause and prompt treatment is mandatory as it represents a medical emergency. Reported amputation rates range from 12% to 25% and mortality ranges from 25% to 40%. Limb ischemia results from obstruction to arterial inflow secondary to extreme levels of venous hypertension. Primary treatment goal is restoration of venous outflow and can be achieved by endovascular or surgical techniques...

Budd-Chiari syndrome (BCS) is a clinical condition resulting from impaired hepatic venous drainage, in which there is obstruction to the hepatic venous outflow at any level from the small hepatic veins to the junction of the inferior vena cava and the right atrium leading to hepatic congestion. The diagnosis of BCS is based on imaging, which can be gathered from non-invasive investigations such as ultrasonography coupled with venous Doppler, triphasic computed tomography (CT) and magnetic resonance imaging (MRI)...

Postthrombotic syndrome (PTS) is the most common complication after iliofemoral deep vein thrombosis. It reduces quality of life and increases deep vein thrombosis (DVT)-related costs. The clinical symptoms and severity of PTS may vary; the most common symptoms include edema, pain (venous claudication), hyperpigmentation, lipodermatosclerosis, and ulceration. PTS is based on the principle of outflow obstruction, which may be caused by venous hypertension and may lead to valvular damage and venous reflux or insufficiency...

A variety of vascular liver disorders can induce hepatocellular tumors. They may be related to portal venous deprivation, venous outflow obstruction, or arterial diseases. Their common feature is an imbalance between hepatic arterial and portal venous blood flow leading to an increased hepatic arterial inflow. Consequently, hepatocellular tumors may arise, most commonly focal nodular hyperplasia-like lesions but hepatocellular adenomas and hepatocellular carcinoma may be seen as well. This article will review the most common vascular liver diseases associated with hepatocellular nodules (Budd-Chiari syndrome, congenital portosystemic shunt, hereditary hemorrhagic telangiectasia, and portal cavernoma)...

PURPOSE OF REVIEW: This article provides an overview of stroke in neonates, infants, and children. RECENT FINDINGS: Arterial ischemic stroke and cerebral venous sinus thrombosis are increasingly recognized in childhood as important causes of lifelong morbidity and mortality. Diagnosis of arterial ischemic stroke is frequently delayed, as acute neurologic deficits can be challenging to detect in the young child, and stroke is often not considered in the differential diagnosis...

Hepatic sinusoidal dilatation refers to the enlargement of the hepatic capillaries. Most of the time this condition is caused by hepatic venous outflow obstruction, which results in vascular stasis and congestion of hepatic parenchyma. In this setting, hepatic sinusoidal dilatation can be related to pericardial disease, heart failure, compression or thrombosis of the hepatic veins or inferior vena cava (i.e., Budd-Chiari syndrome) or central veins/sinusoids involvement (i.e., sinusoidal obstruction syndrome)...

BACKGROUND: Liver resection for intrahepatic cholangiocarcinoma (ICC) with invasion of the inferior vena cava (IVC) and hepatic veins (HV) is a challenging procedure. CASE PRESENTATION: We report a case of a 63-year-old woman with a 6-cm, centrally located liver mass. Her biochemistry results were normal except for a Ca19-9 level of 1199 U/ml. The liver biopsy was consistent with ICC and 60% macrosteatosis. Abdominal CT scans revealed a large central mass invading the left HV, middle HV and right HV, infringing on their junction with the vena cava...

OBJECTIVES: An optimal initial graft function after living-donor liver transplant depends on optimal graft hemodynamics. Nonmechanical impediments to free hepatic venous outflow, due to elevated central venous pressure, may obstruct the "functional" hepatic venous outflow. Here, we evaluated whether central venous pressure affected early graft function and outcomes in adult living-donor liver transplant recipients. MATERIALS AND METHODS: This prospective observational study included 61 living-donor liver transplant recipients without technical complications who received transplants from August 2013 to November 2014...

Budd-Chiari syndrome (BCS) is characterised by obstruction of hepatic venous outflow and may be triggered by the prothrombotic state associated with inflammatory bowel disease (IBD). We reported a case of Crohn's disease (CD) that presented with anasarca, ascites, symptomatic hepatomegaly, elevated liver enzymes, increased prothrombin time and low albumin. Oesophagogastroduodenoscopy and colonoscopy confirmed active CD. Abdominal CT showed hepatic vein thrombosis. Liver biopsy revealed severe perivenular sinusoidal dilation with areas of hepatocyte dropout, bands of hepatocyte atrophy and centrizonal fibrosis, suggestive of BCS...

RATIONALE: Cerebral venous thrombosis (CVT) comprises a group of cerebral vascular diseases resulting from cerebral venous outflow obstruction caused by various etiologies. The etiology of CVT is complex, including infectious and noninfectious factors. The diagnosis is difficult. As a result, many patients are misdiagnosed or never diagnosed. This patient was diagnosed with CVT due to unilateral internal jugular vein compression. PATIENT CONCERNS: In this report, we present a case of acute onset CVT in a 15-year-old female patient who presented with a headache, nausea, and vomiting as the main clinical manifestations...
