BACKGROUND/AIMS: Pneumonia is a significant risk factor for the development of venous thrombosis (VT). Cell-adhesion molecules (CAMs) are linked to the pathogenesis of both pneumonia and VT. We hypothesized that remote infection would confer a prothrombogenic milieu via systemic elevation of CAMs. METHODS: Lung injury was induced in wild-type (C57BL/6) mice by lung contusion or intratracheal inoculation with Klebsiella pneumoniae or saline controls. K. pneumoniae-treated mice and controls additionally underwent inferior vena cava (IVC) ligation to generate VT...

Venous thromboembolism (VTE), which constitutes pulmonary embolism and deep vein thrombosis, is a common disorder associated with significant morbidity and mortality. Landmark trials have shown that direct oral anticoagulants (DOACs) are as effective as conventional anticoagulation with vitamin K antagonists (VKA) in prevention of VTE recurrence and associated with less bleeding. This has paved the way for the recently published guidelines to change their recommendations in favor of DOACs in acute and long-term treatment of VTE in patients without cancer...

Intravenous leiomyomatosis is a benign smooth muscle tumor which despite its histology can have devastating consequences. Furthermore, the clinical manifestations are variable and nonspecific, typically leading to delayed or missed diagnosis. Thus, it is critical for clinicians to be aware of this condition and have a high index of suspicion in a middle-aged woman with a history of uterine leiomyoma presenting with an inferior vena cava mass to enable early diagnosis and treatment. We report a case of a large intravenous leiomyoma which was initially considered to be a very large deep venous thrombosis; with thorough preoperative planning, it was successfully removed intact and in entirety with a single-stage operation...

BACKGROUND: In boron neutron capture therapy (BNCT), positron emission tomography (PET) with 4-borono-2-(18)F-fluoro-phenylalanine (FBPA) is the only method to estimate an accumulation of (10)B to target tumor and surrounding normal tissue after administering (10)B carrier of L-paraboronophenylalanine and to search the indication of BNCT for individual patient. Absolute concentration of (10)B in tumor has been estimated by multiplying (10)B concentration in blood during BNCT by tumor to blood radioactivity (T/B) ratio derived from FBPA PET...

BACKGROUND: The clinical presentation of non-Hodgkin lymphoma (NHL) varies tremendously depending upon the type of lymphoma and the areas of involvement. NHL can rarely present as an abdominal mass compressing the inferior vena cava. The clinical presentation due to obstruction of inferior vena cava has often been called the inferior vena cava syndrome (IVCS). It can present acutely or chronically. CASE PRESENTATION: A 35-year-old male presented with 3 months history of fever, anorexia, weight loss and abdominal discomfort...

OBJECTIVE: Adrenal venous sampling (AVS) is recommended by clinical guidelines to distinguish surgically curable types of primary aldosteronism, but remains widespread underused mainly due to difficulty in successful sampling. When considering that the right adrenal vein is angled caudally, AVS through upper extremity approach may be more appropriate. The purpose of this study was to establish the technique ofAVS via median cubital vein (MCV), and evaluate its safety and feasibility. DESIGN AND METHOD: From January 2012 to June 2015, 194 consecutive patients diagnosed as primary aldosteronism underwent AVS via MCV at the Fuwai Hospital...

A case of pericardial constriction with rhythmic, nonrespiratory pulsations in inferior vena cava is presented. Hepatic vein flow showed wave form classical of pericardial constriction. Backward transmission of changes in right atrial pressure resulted in rhythmic, nonrespiratory pulsations in inferior vena cava. This echocardiographic finding could help in diagnosis of pericardial constriction.

Non-CE MRA techniques (true steady-state free-precession, SSFP) have been used effectively for the selective visualization of the portal venous system and inferior vena cava. Budd-Chiari Syndrome (BCS) encompasses a number of conditions that cause the obstruction of the hepatic outflow tract from the small hepatic veins to the junction of the inferior vena cava (IVC) and right atrium. The purpose of this study was to diagnose BCS with IVC obstruction using respiratory triggered three-dimensional (3D) true SSFP with T-SLIP and compare to digital subtraction angiography (DSA)...

INTRODUCTION: The Fontan procedure (FP) has become the standard operation for patients with single ventricle physiology. However, a long period of elevated systemic venous pressure and low cardiac output after the procedure result in chronic inflammation and liver cirrhosis, which may eventually lead to the occurrence of hepatocellular carcinoma (HCC). CLINICAL FINDINGS: We described the case of a 16-year-old female who developed HCC after the FP. At 21 months, the patient received a lateral tunnel FP, and 14 years later, she began complaining of abdominal distension, telangiectasia, and fatigue...

Background: Percutaneous nephrostolithotomy is an important approach for removing kidney stones. Puncturing and dilatation are two mandatory steps in percutaneous nephrolithotomy (PCNL). Uncommonly, during dilatation, the dilators can cause direct injury to the main renal vein or to their tributaries. Case Presentation: A 75-year-old female underwent PCNL for partial staghorn stone in the left kidney. During puncturing and dilatation, renal vein tributary was injured, and the nephroscope entered the renal vein and inferior vena cava, which was clearly recognized...

INTRODUCTION: Expressing exogenous genes after naked DNA delivery into hepatocytes might achieve sustained and high expression of human proteins. Tail vein DNA injection is an efficient procedure for gene transfer in murine liver. Hydrodynamic procedures in large animals require organ targeting, and improve with liver vascular exclusion. In the present study, two closed liver hydrofection models employing the human alpha-1-antitrypsin (hAAT) gene are compared to reference standards in order to evaluate their potential clinical interest...

BACKGROUND & AIMS: Portal hypertension (PH) is a serious adverse event of liver cirrhosis. The hepatic venous pressure gradient or portal pressure gradient (PPG) accurately reflects the degree of PH and is the single best prognostic indicator in liver disease. This is usually obtained by interventional radiology (IR) although it is not routinely performed. Recently, we developed a simple novel technique for EUS-guided PPG measurement (PPGM). Our animal studies showed excellent correlation between EUS-PPGM and IR-PPGM...

Importance: Trauma patients admitted to the hospital are at increased risk of bleeding and thrombosis. The use of inferior vena cava (IVC) filters in this population has been increasing, despite a lack of high-quality evidence to demonstrate their efficacy. Objective: To determine if IVC filter insertion in trauma patients affects overall mortality. Design, Setting, and Participants: This retrospective cohort study used stratified 3:1 propensity matching to select a control population similar to patients who underwent IVC filter insertion at Boston Medical Center (a level I trauma center at Boston University School of Medicine) between August 1, 2003, and December 31, 2012...
