INTRODUCTION: Hepatoblastoma with tumour thrombi extending into inferior-vena-cava and right atrium are often unresectable with an extremely poor prognosis. The surgical approach is technically challenging and might require major liver resection with vascular reconstruction and extracorporeal circulation. However, which is the best surgical technique is yet unclear. PRESENTATION OF CASE: A 11-months-old boy was referred for a right hepatic lobe mass(90×78mm) suspicious of hepatoblastoma with tumoral thrombi extending into the inferior-vena-cava and the right atrium, bilateral lung lesions and serum alpha-fetoprotein level of 50...

Recent advances in atherosclerotic plaque detection have shown that not only does lipid core size and depth play important roles in plaque rupture and thrombi formation, but lipid composition, especially cholesterol deposition, is equally important in determining lesion vulnerability. Here, we demonstrate a spectral analysis assisted photoacoustic imaging approach to differentiate and map lipid compositions within an artery wall. The approach is based on the classification of spectral curves obtained from the sliding windows along time-of-flight photoacoustic signals via a numerical k-means clustering method...

Aneurysm of the proximal ulnar artery is extremely rare. Ultrasonography, computed tomography and magnetic resonance imaging generally provide accurate diagnosis of aneurysm. A 29 year-old woman who had undergone an excision biopsy of a mass in her right arm by an orthopedic surgeon was referred to our department. We resected the mass and interposed it with a reversed great saphenous vein. Histopathological examination suggested that the mass was a pseudoaneurysm consisting of organized thrombi with recanalization...

The post-Pulmonary Embolism (post-PE) syndrome is being increasingly recognized as a long-term consequence of PE. Its most severe manifestation, chronic thromboembolic pulmonary hypertension (CTEPH), affects a small proportion of PE survivors. However, many more with less severe post-PE syndrome have reduced quality of life and functional capacity. The pathophysiology is incompletely understood, but involves unresolved pulmonary artery thrombi, right ventricular damage, and abnormal gas exchange. Treatment has only been established for CTEPH, and further studies are required to determine how less severe forms of the post-PE syndrome should be treated and if preventive strategies can reduce its incidence...

Venous thromboembolism (VTE) is a significant problem in the perioperative period, increasing patient morbidity, mortality, and health care costs. It is also considered the most preventable of the major postoperative complications. Despite widespread adoption of prophylaxis guidelines, it appears that morbidity from the disease has not substantially changed within the past 2 decades. It is becoming clear that current prophylaxis efforts are not sufficient. Using more potent anticoagulants may decrease the incidence of VTE, but increase the risk for bleeding and infection...

The clinical impact of in-stent thrombosis is high because it is associated with high mortality and 20 % of the patients suffer a recurrent event within the two following years. The aim of this study was to characterise the morphologic and proteomic profile of in-stent thrombi (IST) in comparison to thrombi developed on native coronary arteries (CT) to identify a differential molecular signature. The study included 45 patients with ST-elevation-myocardial-infarction (STEMI) treated by primary-percutaneous-intervention and thrombus aspiration: 21 had IST and 24 had CT...

BACKGROUND AND PURPOSE: The introduction of stent retrievers allows for a complete extraction and histological analysis of human thrombi. Ischemic stroke is a major health issue, and differentiation of underlying causes is highly relevant to prevent recurrent stroke. Therefore, histopathologic analysis of the embolic clots after removal may provide valuable information about underlying pathologies. This study analyzes histological clot composition and aims to identify specific patterns that might help to distinguish causes of ischemic stroke...

Handling and restraining rabbits for routine procedures may be impossible without prior sedation, result in unnecessarystress or injury to the rabbit or handler, and increase experimental variability. Parenteral administration of sedatives can cause stress also, as well as localized pain and tissue damage, especially in fractious animals. Detomidine hydrochloride, an α2-adrenergic receptor agonist, is commercially available in an oral transmucosal (OTM) gel formulation that is FDA-approved for sedation and restraint in horses...

Right heart thrombus in transit is an increasingly recognized medical emergency with very high mortality rate. Echocardiography helps to establish the diagnosis and can differentiate between right heart thrombi that result from atrial fibrillation and those originating from deep venous thrombosis. We present two cases of right heart thrombus in transit diagnosed with echocardiography that were managed with different approaches.

BACKGROUND: The diagnosis of thrombus in the left atrium in patients with persistent atrial fibrillation (AF) and may be inconsistent because of variability in thrombus morphology. In some cases it is challenging and requires unusual approach. New Doppler-derived methods might be helpful to identify such thrombi. We evaluated quantitative differences in mechanical function of the left atrial appendage (LAA) basal segments using tissue Doppler imaging (TDI)and speckle tracking echocardiography (STE) in patients with non-valvular AF with and without LAA thrombus and compared them with SR patients...

: Giant left atrium is frequently associated with rheumatic mitral valve disease. The incidence of left atrial thrombus among patients with mitral stenosis and atrial fibrillation varies from 7 to 38%. Anticoagulation therapy achieves a high rate of resolution of left atrial appendage (LAA) and left atrial cavity thrombi, but in selected patients surgical therapy must be considered. An 81-year-old woman presented to our emergency department with repeated episodes of transient ischemic attack. She had a history of carotid artery stenosis, chronic lymphocytic leukemia, rheumatic heart disease, and paroxysmal atrial fibrillation...

PURPOSE: To investigate whether the results of early tests for hypercoagulability are correlated with the development of central retinal vein occlusion risk factors later in life and to evaluate the necessity of these tests in younger patients. METHODS: This was a retrospective, observational case series. From January 1995 to December 2014, 55 patients aged below 56 years with central retinal vein occlusion (CRVO) were enrolled in the study. Laboratory evaluations for homocysteine, activated protein C resistance, protein C activity, protein S activity, antithrombin III activity, antiphospholipid antibodies, and anticardiolipin antibodies were obtained at the onset of CRVO...

The amyloid precursor protein (APP), primarily known as the precursor of amyloid peptides that accumulate in the brain of Alzheimer's disease patients, is abundant in platelets but its physiological function remains unknown. In this study, we investigated the role of APP in hemostasis and thrombosis using APP knockout (KO) mice. Ex vivo aggregation, secretion, and integrin αIIbβ3 inside-out activation induced by several agonists were normal in APP-deficient platelets, but the number of circulating platelets was reduced by about 20%, and their size was slightly increased...

Background and purpose Because computed tomography (CT) is the most commonly used imaging modality for the evaluation of acute ischemic stroke patients, developing CT-based techniques for improving clot characterization could prove useful. The purpose of this in-vitro study was to determine which single-energy or dual-energy CT techniques provided optimum discrimination between red blood cell (RBC) and fibrin-rich clots. Materials and methods Seven clot types with varying fibrin and RBC densities were made (90% RBC, 99% RBC, 63% RBC, 36% RBC, 18% RBC and 0% RBC with high and low fibrin density) and their composition was verified histologically...

BACKGROUND AND PURPOSE: Increasing thrombus length (TL) impedes recanalization after intravenous (IV) thrombolysis. We sought to determine whether the clinical benefit of aspiration thrombectomy relative to IV r-tPA (recombinant tissue-type plasminogen activator) may be greater at longer TL. METHODS: THERAPY was a randomized trial of aspiration thrombectomy plus IV r-tPA versus IV r-tPA alone in large-vessel stroke patients with prospective TL measurement ≥8 mm...

Thromboembolic cerebrovascular accident remains a rare but potentially devastating complication of catheter-based atrial fibrillation (AF) ablation. Uninterrupted oral anticoagulant therapy with warfarin has become the standard of care when performing catheter-based AF ablation. Compared with warfarin, apixaban, a factor Xa inhibitor, has been shown to reduce the risk of stroke and major bleeding in nonvalvular AF. With an increase in apixaban use for stroke prophylaxis in patients with AF, there is an increased interest in the safety and efficacy of uninterrupted apixaban therapy during AF ablation...

Atrial fibrillation (AF) is a common type of arrhythmia that increases significantly the risk of blood clots in the heart and of stroke. Therefore, stroke prevention is a key goal of AF treatment. In the past, patients were required to take anticoagulants for the remainder of their life, to regularly the monitor international normalized ratio (INR) of prothrombin time (PT), and to avoid possible negative interactions with various drugs and foods. Left atrial appendage occlusion (LAAO), a novel device and technique, was thus developed for AF patients with contraindications to anticoagulants and a high risk of bleeding...
