Pulmonary embolism as a part of venous thromboembolic disease has a broad spectrum of clinical presentations from minimal disease to life-threatening right heart failure. Therapy has to be guided by the risk associated with the individual clinical state of the patient. As long as hemodynamics are entirely stable, anticoagulation is given in order to prevent early or late recurrence, thereby allowing for endogeneous thrombolysis and recovery.

Abstract:

Thesis (M.A.)--Boston University<br>Background: Pulmonary embolism (PE) is a rare condition associated with high morbidity and mortality in children. The diagnosis of PE in children is challenging, considering the often non-specific clinical signs and symptoms associated with this condition. Computed tomography with pulmonary angiography (CTPA) is currently the diagnostic gold standard, but carries the risk of radiation-induced malignancy. For these reasons, the optimal diagnostic management strategy for the care of children with suspected PE in the emergency department (ED) setting is undefin

Abstract:

Background Acute pulmonary embolism (PE) carries a high burden of mortality and morbidity. PE remains the third leading cause of cardiovascular mortality and carries a substantial economic burden which is driven by the costs of hospitalization. Low-risk PE is safely managed as an outpatient, thus accurate assessment of prognosis is an important part of the management of patients presenting to hospital with PE. Current guidelines recommend the use of clinical risk scores such as the Pulmonary Embolism Severity Index (PESI) or its simplified version (sPESI).There remains scope for refining thes

Abstract:

Pulmonary embolism (PE) is an obstruction within the pulmonary arterial tree and in the majority of cases arises from a thrombosis that has travelled to the lungs via the venous system. Pulmonary embolism (PE) is a fatal condition which affects all age groups and is the third most common cause of death in the US. Computed tomographic angiography (CTA) imaging has recently emerged as an accurate method in the diagnosis of pulmonary embolism. Each CTA scan contains hundreds of CT images, so the accuracy and efficiency of interpreting such a large image data set is complicated due to various PE l

Abstract:

Pulmonary embolism (PE) is a common clinical problem affecting 600,000 patients per year in the United States. Although the diagnosis can be easily confirmed by imaging techniques, such as computed tomographic angiography of the chest, the identification of underlying mechanism leading to PE is important for appropriate duration of anticoagulation, and prevention of subsequent episodes. The differential diagnosis of underlying mechanism is broad and must include careful review of medication history. Drug-related thromboembolic disease can be easily missed and may have catastrophic consequences

Pulmonary embolism (PE) and schizophrenia are common and life threatening conditions with long-term mortality due to cardiovascular and non-cardiovascular causes. In both conditions, the predictors of long-term dysfunction or mortality are poorly studied but both are suspected to have subclinical cardiac dysfunction which has not been defined. The increased risk of thrombosis recurrence in patients with PE, and thrombosis incidence in patients with schizophrenia indicates a shared predisposition to thrombosis in these conditions.

Diana.sobieraj@hhchealth.org<br>Objective To systematically review the literature and to quantitatively evaluate the efficacy and safety of extended pharmacologic treatment of venous thromboembolism (VTE) through network meta-analysis (NMA). Methods A systematic literature search (MEDLINE, Embase, Cochrane CENTRAL, through September 2014) and searching of reference lists of included studies and relevant reviews was conducted to identify randomized controlled trials of patients who completed initial anticoagulant treatment for VTE and then randomized for the extension study; compared extension

Abstract:

INTRODUÇÃO: A hipertensão pulmonar tromboembólica crônica (HPTEC) é uma doença vascular pulmonar progressiva, cuja incidência varia de 0,56% a 3,2% em indivíduos com embolia pulmonar aguda (EPA) recorrente. Apesar do avanço nas opções de tratamento para HPTEC, a tromboendarterectomia pulmonar (TEAP) continua sendo padrão ouro, levando a melhora hemodinâmica e aumento da sobrevida. OBJETIVOS: Avaliar o impacto que mudanças técnicas intraoperatórias implementadas tiveram na evolução dos pacientes submetidos à TEAP em relação à morbimortalidade imediata e tardia, e também sobre o desenvolvimento

Abstract:

INTRODUCTION: Pulmonary embolism (PE) is a major cause of mortality during pregnancy. It is estimated that about 20% of maternal deaths in north america are due to PE. A lung V/Q study in a standard (non-gravid) patient typically consists of a low dosage ventilation study followed by a higher dosage perfusion study. In some centers however, perfusion-only imaging, without accompanying ventilation imaging has been employed. In this method, a several-fold lower dose of radioactivity is used. Perfusion-only imaging has multiple advantages. In addition to reduction of radiation dose to the moth

Abstract:

Background: Pulmonary embolism (PE) accounts for almost 40% of perioperative deaths after bariatric surgery. Placement of prophylactic inferior vena cava (IVC) filter before bariatric surgery to improve outcomes has shown varied results. We performed a meta-analysis to evaluate postoperative outcomes associated with the preoperative placement of IVC filters in these patients. Methods: A systematic review was conducted by three investigators independently in PubMed, EMBASE, the Web of Science and Scopus until February 28, 2013. Our search was restricted to studies in adult patients undergoing b

Abstract:

INTRODUÇÃO: Os tomógrafos multidetectores (TCMD) aumentaram a sensibilidade na detecção do tromboembolismo pulmonar (TEP). Observa-se, no entanto, um substancial aumento no número de imagens e, conseqüentemente, no tempo de análise pelo radiologista. Uma possível solução, para este problema, é a realização de reconstruções em projeção de intensidade máxima (MIP) que reduz o número de imagens para análise. Existe ainda uma nova modalidade de imagem utilizando reconstrução MIP em planos rotacionais sobre um eixo horizontal ao nível dos hilos pulmonares (reformatação em pás de roda moinho, PRM),

Abstract:

This thesis investigates the feasibility of low-dose multi-slice CT pulmonary angiography in the diagnosis of pulmonary embolism based on experiments on a 3D printed realistic pulmonary artery model and patient data analysis. The research findings show that significant dose reductions in radiation dose and contrast medium have been achieved using low-dose CT pulmonary angiography protocols without affecting diagnostic image quality.

There are many studies on V/Q SPECT using Technegas as a ventilation agent but very limited studies available on 81m Kr gas. Aim: To

Abstract:

Introduction: The diagnosis of Pulmonary Embolism (PE) is challenging to make and is often missed in the Emergency Centre. The true incidence of PE in South Africa is unknown. The diagnostic work-up of PE has been improved by the use of Clinical decision rules (CDRs) and CT Pulmonary Angiography (CTPA) in high-income countries. Currently used CDRs have not been validated in the South African environment, where HIV and TB are highly prevalent. Both conditions are known to induce a hyper-coagulable state. Methods: This study was a retrospective chart review of patients with suspected PE that had

Abstract:

The intensive care unit treats the most critically ill patients in the hospital, and as such the clinical staff in the intensive care unit have to deal with complex, time-sensitive and life-critical situations. Commonly, patients present with multiple organ dysfunctions, require breathing and cardiovascular support, which make diagnosis and treatment even more challenging. As a result, clinical staff are faced with processing large quantities of often confusing information, and have to rely on experience and trial and error. This occurs despite the wealth of cardiovascular metrics that are ava

Відомо, що серед пацієнтів терапевтичного профілю найчастіше ТЕЛА виникає при інсульті (65%), інфаркті міокарда (ІМ) (22%), а також у людей похилого віку (9%). Це призводить до розвитку гіпертензії малого кола кровообігу та легеневого серця. Мета. Визначити перспективу застосування D-димеру для діагностики ТЕЛА.
