A cavopulmonary assist device (CPAD) has been developed for failing Fontan support. This CPAD pumps blood from superior/inferior vena cavae to pulmonary artery. In this study, we compared failing Fontan support with CPAD versus VA ECMO in silico. A numerical lumped-parameter circulatory system model was used to simulate Fontan circulation. Failing Fontan was simulated by increased pulmonary resistance. Central venous pressure (CVP), mean pulmonary arterial pressure (mPAP), left atrial pressure (LAP), and univentricular outflow (CO) were simulated and compared to published clinical data...

INTRODUCTION: Venous thromboembolism is a multicausal disease. Understanding interactions between risk factors is the key to advance knowledge about the etiology of venous thrombosis. These interactions are still unclear. In addition to traditional risk factors, there is data about many other risk factors, recorded with few populations based prospective epidemiologic studies or punctually reported. Interactions between these risk factors remain unclear. The aim of our work is to identify and analyze combinations of risk factors...

BACKGROUND: Isolated superficial vein thrombosis (iSVT) (without concomitant deep vein thrombosis (DVT) or pulmonary embolism (PE)) is a frequent event but available data on long-term outcomes are scarce and retrospective. Therefore, we aimed to determine prospectively the risk and type of venous thromboembolic (VTE) recurrence after iSVT and compare it with that of proximal DVT. METHODS: Using data from the prospective, multicentre, observational, OPTIMEV study, we assessed at three years and after anticoagulants were stopped, the incidence and the type of VTE recurrence (iSVT/DVT/PE) of patients with a first objectively confirmed iSVT without cancer (n=285) and compared this to patients with a first proximal DVT without cancer (n=262)...

Objective: To investigate the risk factors of pulmonary embolism (PE) in senile and non-senile inpatients, and evaluate the predictive value of Caprini risk assessment model in these two populations. Methods: Case control study design was used in this study. All the PE patients diagnosed in West China Hospital of Sichuan University between January 2012 and December 2014 was included and divided into senile PE group (age ≥65 years old) and non-senile PE group (age <65 years old). Age matched controls (senile control group and non-senile control group) were selected from the patients admitted into the same departments during the same time period as PE patients, at a ratio of 2∶1...

BACKGROUND: The optimal management of patients with isolated distal deep vein thrombosis (IDDVT) concerning both the need for anticoagulation and its duration is undefined. OBJECTIVES: We performed a meta-analysis of randomized and cohort studies in patients with IDDVT to assess the clinical benefit of i) anticoagulation versus no anticoagulation and ii) anticoagulant treatment for 6 weeks vs. more than 6 weeks. METHODS: The primary outcome of this analysis was recurrent venous thromboembolism (proximal propagation, recurrence of deep vein thrombosis and pulmonary embolism)...

Rivaroxaban, dabigatran, apixaban and edoxaban are the four available new oral anticoagulants (NOAC) which are currently approved for venous thromboembolism prophylaxis after total hip and knee replacement. Large phase 3 and phase 4 studies comparing NOAC with low molecular weight heparins have shown similar results regarding the efficacy and safety of these two categories of anticoagulants. Management of bleeding complications is a matter of great significance. Three reversal agents have been developed: idarucizumab, andexanet alfa and ciraparantag...

Changes in the incidence of venous thromboembolism (VTE) during the last two decades have not been extensively studied. Therefore, we studied time trends in the incidence rates (IRs) of deep vein thrombosis (DVT) and pulmonary embolism (PE) in a cohort of 26,855 subjects, aged 25-97 years, enrolled in the Tromsø study in 1994/1995. The subject were followed-up throughout 2012, and all symptomatic, objectively confirmed, incident VTEs were identified using multiple sources (hospital discharge-, radiology procedure- and autopsy registry) and validated by review of medical records...

Developmental venous anomalies (DVAs) are congenital anatomical variants of normal venous drainage of normal brain. Although DVAs are often discovered on the occasion of a seizure, their involvement in epilepsy is poorly studied. Our objective was to determine whether DVA can cause seizures, in the cases where there is no associated lesion, including no cavernoma or dysplasia. Based on clinical history, cerebral MRI, EEG recording, and (18)F-FDG PET, we report 4 patients with DVA revealed by seizures. The first patient had a convulsive seizure caused by a hemorrhagic infarction due to thrombosis of her DVA...

A young woman developed a line-associated deep vein thrombosis (DVT), which was treated with low molecular weight heparin (dalteparin). 8 days later, the DVT had significantly extended-in spite of therapeutic heparin levels. A diagnosis of heparin-induced thrombocytopenia and thrombosis (HITT) was considered, but the platelet count had not dropped. Nevertheless, a HITT assay was carried out which came back positive, with a repeat assay confirming the result. Dalteparin was stopped and apixaban treatment started, with symptomatic recovery over the following days and weeks...

Small bowel intussusception (SBI) in pediatric patients resolves spontaneously in the majority of cases. Pathologic small bowel intussusception with a lead point is rare in children. Ultrasound (US) is the preferred initial imaging study for the diagnosis of intussusception. We report a case of long-segment SBI and secondary bowel obstruction caused by a large hamartomatous polyp. This case emphasizes unique, atypical ultrasound findings that may be encountered in small bowel intussusception, with correlative radiographic, CT (computed tomography) and intra-operative findings...

PURPOSE OF REVIEW: Symptoms suggestive of deep vein thrombosis (DVT) are extremely common in clinical practice, but unfortunately nonspecific. In both ambulatory and inpatient settings, clinicians are often tasked with evaluating these concerns. Here, we review the most recent advances in biomarkers and imaging to diagnose lower extremity DVT. RECENT FINDINGS: The modified Wells score remains the most supported clinical decision rule for risk stratifying patients...

L-Arginine (L-arg), widely known as a substrate for endogenous nitric oxide synthesis, can improve endothelial function associated with the vasculature, inhibit platelet aggregation, and alter the activity of vascular smooth muscle cells. P-selectin is a membrane component of the platelet alpha-granule and the endothelial cell-specific Wiebel-Palade body that plays a central role in mediating interactions between platelets and both leukocytes and the endothelium. The experiment was designed to evaluate the effect of novel microspheres with L-arg targeting P-selectin on the formation of deep vein thrombosis and repair of vascular wall in a rat model...

An in-depth focused study of specific cases of patients with recurrent thrombosis may help to identify novel circumstances, genetic and acquired factors contributing to the development of this disorder. The aim of this study was to carry out a detailed and sequential analysis of samples from a patient suffering from early and recurrent venous and arterial thrombosis. We performed thrombophilic tests, biochemical, functional, genetic and glycomic analysis of antithrombin and other plasma proteins. The patient carried a new type I antithrombin mutation (p...

Selectins, such as E-selectin (CD62E), function in venous thrombosis by binding and activating immune cells to initiate the coagulation cascade. GMI-1271 is a small molecule antagonist that inhibits E-selectin activity. Here we determine whether inhibition of E-selectin is sufficient to decrease acute venous thrombosis and associated inflammatory events in both prophylactic and treatment protocols without significantly affecting haemostasis. Male C57BL/6 mice underwent surgery for experimental thrombosis induction and were harvested at peak thrombus formation in our animal model, two days post induction...

Inherited quantitative (type I) or qualitative (type II) antithrombin deficiency (ATD) due to mutations in the SERPINC1 gene is a well-known risk factor for venous thromboembolism. ATD may also increase risk for arterial thrombosis. Few studies have investigated risk for thrombosis according to mutations. We addressed this topic in a large retrospective cohort study of 540 heterozygous carriers of SERPINC1 mutations and compared risk for first venous or arterial thrombosis associated with carrying of different type II or type I mutations...

Cerebral venous sinus thrombosis (CVST) is common in Asians, accounting for 15% of all strokes in the young. CVST causing malignant cerebral oedema with brain herniation and death are referred as malignant CVST. This study was aimed at evaluating the outcome of patients and factors predicting the outcome with malignant CVST after decompressive surgery. It was a retrospective, observational, single centre, hospital-based and cross-sectional study. Records of patients with malignant CVST who had decompressive surgery were analysed...
