The currently available randomized data provide no evidence of benefit of thrombolytic therapy compared with heparin for the initial treatment of unselected patients with acute pulmonary embolism. However, subgroup analyses indicate a benefit of thrombolysis compared with heparin in trials that included patients with major pulmonary embolism but no benefit in trials that excluded these patients. This apparent heterogeneity of treatment effect appears to be due to an effect of thrombolytic therapy on death, the incidence of which was approximately 5-fold higher in heparin-treated patients enrolled in trials that also included patients with major pulmonary embolism. Patients at risk of dying of major pulmonary embolism are also those most likely to achieve benefit from thrombolytic therapy, because more rapid clot lysis can reverse hypotension and prevent irreversible shock that leads to death.. Registry data indicate that right ventricular dysfunction in patients with acute pulmonary embolism is ...

The concentration of fibrin split products (FSP) was measured, by using a modification of the staphylococcal clumping test, in 46 patients who had pulmonary angiography for suspected acute pulmonary embolism and in 12 normal control subjects. The concentration was significantly higher in 19 patients with angiographically documented pulmonary embolism (mean FSP, 158 µg/ml) than in 22 patients without (mean, 8 µg/ml; P , 0.001)-in 18 of the 19 patients the concentration was , 10 µg/ml; in 19 of the 22 patients without pulmonary embolism it was 10 µg/ml or less. The levels were highest in patients with acute symptoms (,3 days) and in those with significant increases in total pulmonary resistance, as measured at cardiac catheterization. Fibrin split products concentration seems to be increased (,10 µg/ml) in most patients with acute pulmonary embolism. We had only one false-negative finding; however, the specificity of an elevation of this variable in acute pulmonary embolism needs further ...

The same initial and long-term anticoagulation is suggested for unsuspected pulmonary embolism as for patients with symptomatic embolism. Based on these indications, cancer patients with unsuspected pulmonary embolism would be anticoagulated for at least 6 months or until the disease is active, which in most cases would mean indefinite treatment. In fact, dedicated studies on the treatment of unsuspected pulmonary embolism are missing, leaving doubts over the need for (indefinite) anticoagulation which exposes these patients to an increased risk of major bleeding events. Concerns over the need for anticoagulant treatment may especially hold for pulmonary embolism of the distal pulmonary tree since segmental and sub-segmental PE seem to have a more benign course than more proximal embolism.. The scope of this study is to evaluate the current treatment approaches for unsuspected pulmonary embolism and to assess their efficacy and safety in a large prospective cohort of cancer patients. ...

Streptokinase therapy for the treatment of massive pulmonary embolism is superior to heparin therapy, although infusion of the recommended doses through a peripheral vein carries a substantial risk of hemorrhagic complications. By infusing low doses of this fibrinolytic agent through a pulmonary catheter in proximity to the embolic obstruction, rapid resolution of the pulmonary embolism can be accomplished. The induction of a local fibrinolytic state carries less risk of hemorrhagic complications than conventional streptokinase therapy. Further clinical studies are needed; however, this method of treatment of potentially fatal massive pulmonary embolism offers an attractive alternate to utilization of a fibrinolytic agent through a peripheral vein. The reduced risk of hemorrhagic complications could broaden its indications for therapy for pulmonary embolism to include situations in which embolic pulmonary obstruction has a high incidence of occurrence, that is, the postoperative state or the post
The association between prolonged sitting and pulmonary embolism was first reported among air raid shelter users in London during World War II," said Mr Shirakawa. "Nowadays, a long haul flight in an economy class seat is a well known cause of pulmonary embolism that is called economy class syndrome.". He continued: "Pulmonary embolism is a serious, sometimes fatal, lung-related vascular disease characterised by sudden onset of symptoms such as chest pain or difficulty breathing. The disease is caused by obstruction of the pulmonary arteries by blood clots, generally formed in the leg vessels. Risk factors include cancer, prolonged bed rest or sitting, and oral contraceptive use.". The current study is the first prospective assessment of the association between prolonged television watching and fatal pulmonary embolism. The study included 86 024 participants (36 007 men and 50 017 women) aged 40 to 79 years who completed a self administered questionnaire including information about average ...
Multislice CT has been widely used in clinical practice for diagnosing cardiovasculardisease due to its reduced invasiveness and its high spatial and temporalresolution. As a reliable alternative to conventional pulmonary angiography, multisliceCT angiography has been recognized as the first line technique for detectingand diagnosing pulmonary embolism. A pulmonary embolism located in the mainpulmonary artery, as well as being located in the segmental branches, can beaccurately detected with multislice CT imaging, and especially with the use of 16-and 64-slice CT scanners. Visualization of pulmonary embolisms has traditionallybeen limited to 2D, multiplanar reformation and the 3D external surface visualizations.In this pictorial review, we present our experience of using 3D virtualintravascular endoscopy (VIE) to characterize and evaluate the intraluminalappearance of pulmonary embolisms in a group of patients who were suspectedof having pulmonary embolism and who were undergoing multislice CT ...

N2 - Septic pulmonary embolism (SPE) results when fragments of thrombus containing bacteria or fungi travel to the pulmonary circulation and lodge in segmental and subsegmental pulmonary arteries. Almost invariably such embolization implies the presence of an endovascular infection (typically endocarditis, septic thrombophlebitis, or catheter-related infection) as the source of embolism. Here we report a case of Staphylococcus aureus bacteremia complicated with SPE in a patient who had no septic foci other than a soft tissue infection. We found 17 similar cases in the literature and reviewed their clinical presentation and outcomes. The most common presenting symptoms were ...
Introduction: Pulmonary embolism (PE) affects 60-70 per 100,000 population. PE can be risk stratified into non massive, sub massive and massive based on clinical presentation and clot burden. Catheter directed thrombolysis (CDT) is a current strategy for management of massive PE (Class IIa) and has also been recommended by AHA for patients with submassive PE (Class IIb). Ultrasound enhanced (UE) CDT combines ultrasonic clot destruction with local thrombolysis and has been shown to reduce right ventricular dilation (RVD) and clot burden.. Objective: To evaluate the overall effectiveness of UE CDT in the management of massive and submassive PEs.. Methods: A retrospective cohort of consecutive patients with massive or submassive PE presenting to the ED between 2010-2016, and treated with UE CDT were included in the study. Demographic data along with complications, mortality rate and echocardiographic findings were abstracted from electronic medical records. The calculated Pulmonary Embolism ...

An angiogram, also called an arteriogram, is an X-ray image of the blood vessels. It is performed to evaluate various vascular conditions, such as an aneurysm (ballooning of a blood vessel), stenosis (narrowing of a blood vessel), or blockages.. A pulmonary angiogram is an angiogram of the blood vessels of the lungs. A pulmonary angiogram may be used to assess the blood flow to the lungs. One of the primary indications for the procedure is the diagnosis of a pulmonary embolus (clot). It may also be used to deliver medication into the lungs to treat cancer or hemorrhage.. In order to obtain a radiographic (X-ray) image of a blood vessel, an intravenous (IV) access is necessary so that a contrast dye can be injected into the bodys circulatory system, which includes the pulmonary (lungs) circulatory system. This contrast dye causes the blood vessels to be visible on X-ray film. This allows the doctor to see the size, shape, and many branches of the pulmonary vessels, in particular, the pulmonary ...
Acute venous thromboembolism resolves in most cases. However, an estimated 0.5%-3.8% of pulmonary embolism (PE) survivors develop chronic thromboembolic pulmonary hypertension (CTEPH) resulting from mechanical obstruction of the pulmonary arteries [1-3]. Most patients with CTEPH have experienced a PE in their lifetime; however, up to 25% of patients have never reported a thrombotic event [4].
Chronic thromboembolic pulmonary hypertension (CTEPH) is an uncommon consequence of acute pulmonary embolism. We report CTEPH in a 58-year-old male who had pleurisy with a small haemorrhagic pleural effusion three months ago. The six-month course of

CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). It is a preferred choice of imaging in the diagnosis of PE due to its minimally invasive nature for the patient, whose only requirement for the scan is an intravenous line. Modern MDCT (multi-detector CT) scanners are able to deliver images of sufficient resolution within a short time period, such that CTPA has now supplanted previous methods of testing, such as direct pulmonary angiography, as the gold standard for diagnosis of pulmonary embolism. The patient receives an intravenous injection of an iodine-containing contrast agent at a high-rate using an injector pump. Images are acquired with the maximum intensity of radio-opaque contrast in the pulmonary arteries. This can be done using bolus tracking. A normal CTPA scan will show the contrast filling the pulmonary vessels, appearing as ...

There have been 2 main treatments for acute pulmonary embolism (PE)-anticoagulant therapy alone or systemic thrombolytic therapy. Although systemic thrombolytic therapy is effective at preventing deaths from PE, it markedly increases bleeding, including intracranial and fatal bleeding (1). The recent PEITHO (Pulmonary Embolism Thrombolysis Study) (2), which compared tenecteplase with placebo in 1,000 PE patients without hypotension but with right ventricular dysfunction, found no clear net benefit from systemic thrombolytic therapy; the reduction in cardiovascular collapse (odds ratio: 0.30) was offset by the increase in major bleeding (odds ratio: 5.2). Consequently, systemic thrombolytic therapy is usually reserved for PE patients with hypotension (3). The ability to actively remove thrombus in patients with acute PE without increasing bleeding would be an important advance. Catheter-based therapy has that potential.. Catheter-directed thrombolysis (CDT) was initially developed for treatment ...

Septic pulmonary embolism (SPE) is an uncommon disease caused by thromboembolism associated with microorganisms. A 57-year old woman patient who was monitored for a prediagnosis of subileus suffered from sudden respiration problems in the hospital ward. The patient s history included atrial fibrillation and atrioseptal defect (ASD) operation. The patient was admitted to the intensive care unit (ICU) in order to apply non-invasive mechanical ventilation and keep her under observation because of low saturation and loss of consciousness. In the ICU, the patient s temperature was 38.8 C, which led to the diagnosis of sepsis. The chest X-ray showed bilateral and multiple patchy infiltrates. The thorax CT showed right lower pulmonary consolidation and left pulmonary pleuroparenchymal density with nodular shapes. The electrocardiogram showed mild pulmonary hypertension and third-degree tricuspid failure. These features indicated SPE because of the ASD operation in the past. The blood culture showed the ...
Pulmonary embolism (PE) is a common finding in patients with underlying malignancy and is the commonest cause of acute cor pulmonale. A 65-year-old woman with a background of non-small-cell lung cancer presented to the emergency department with nausea and vomiting after starting erlotinib; she was pyrexial and had raised C-reactive protein. Despite aggressive fluid resuscitation and antibiotics the patient remained tachycardic, hypotensive, profoundly hypoxic and had a persistent raised jugular venous pulse. Massive PE was therefore suspected. A bedside echocardiogram demonstrated a dilated right ventricle and evidence of pulmonary hypertension. A CT pulmonary angiogram excluded a PE but revealed progression of the right hilar tumour causing complete obstruction of the right upper and middle lobe pulmonary arteries. This case highlights an important differential diagnosis when assessing patients with an underlying intrathoracic tumour with findings suggestive of PE and the importance of ...

Despite this substantial public health burden, no systematic collection of VTE-related morbidity and mortality data exists in the U.S. The available information about disease prevalence and incidence consists of estimates based mainly on population-based epidemiologic studies and analysis of hospital discharge or health insurance claims databases. The limited scope of the available data has raised the question of whether a systematic surveillance system for VTE should be established. ...
September 15, 2015-A study of risk factors associated with symptomatic pulmonary embolism (PE) in patients with deep venous thrombosis (DVT) in lower limbs treated by catheter-directed thrombolysis (CDT) without inferior vena cava (IVC) filter placement was conducted. F.H. Li, MD, et al published the findings online ahead of print in the European Journal of Vascular & Endovascular Surgery (EJVES).. The investigators found that the risk of developing symptomatic PE is most markedly increased in patients with previous silent PE and heart disease; therefore, they concluded that selective (rather than routine) IVC filter placement is an appropriate approach.. As summarized in EJVES, the investigators studied 266 patients with acute/subacute iliofemoral, iliofemoropopliteal, and femoropopliteal thrombosis confirmed by computed tomography venography or ultrasound Doppler. All patients were treated with CDT, with computed tomography pulmonary angiography (CPTA) examination performed in all patients ...

Pulmonary embolism (PE) is a blockage of the main pulmonary artery or one of its branches by a substance that has travelled from elsewhere in the body through the bloodstream (embolism). Pulmonary embolism (PE) is the third most common cause of cardiovascular related mortality. Numerous diagnostic tools have been utilized in order to improve diagnosis and prompt appropriate treatment. Since the first introduction of Computed Tomography (CT) angiography in the setting of PE diagnosis algorithm, it has rapidly become as the first choice among imaging techniques. However, still there is long way to improve the abilities and lowering the possible hazards and problems. The purpose of this review is to evaluate and summarize the role of imaging tools in diagnosis of PE in suspected patients, with particular focus on CT angiography. We studied different areas related benefits, disagreements and challenges in utilizing CT angiography in the setting of PE diagnosis algorithm. Although CT angiography is still

Symptoms of pulmonary embolism are typically sudden in onset and may include one or many of the following: dyspnea (shortness of breath), tachypnea (rapid breathing), chest pain of a "pleuritic" nature (worsened by breathing), cough and hemoptysis (coughing up blood).[16] More severe cases can include signs such as cyanosis (blue discoloration, usually of the lips and fingers), collapse, and circulatory instability because of decreased blood flow through the lungs and into the left side of the heart. About 15% of all cases of sudden death are attributable to PE.[2]. On physical examination, the lungs are usually normal. Occasionally, a pleural friction rub may be audible over the affected area of the lung (mostly in PE with infarct). A pleural effusion is sometimes present that is exudative, detectable by decreased percussion note, audible breath sounds, and vocal resonance. Strain on the right ventricle may be detected as a left parasternal heave, a loud pulmonary component of the second heart ...

An illustration of a blockage in an artery in the lungs, known as a pulmonary embolism. A pulmonary embolism is most often caused by a deep vein thrombosis, a blood clot (thrombus) in the deep veins of the legs or pelvis, which may break apart, creating an embolus which migrates to the lungs. A small embolus may not present any symptoms, and can dissolve in the lungs over time. A large embolus can result in sudden death if blood cannot reach a large portion of the lung, resulting in cyanosis, difficulty breathing, chest pain, heart palpitations and collapse. - Stock Image C027/7039
Two catheter versions were tested. Version I (applied in patients 1-10) had a pigtail tip with an outer diameter of 8 mm and was embedded in a long sheath. Because of technical limitations of the fragmentation procedure in some of the patients, the design was improved. Version II (applied in patients 11-20) consisted of two catheters, one with a 12-mm pigtail for the main pulmonary arteries and one with 8-mm diameter for the lobar arteries.. In all patients, transesophageal or transthoracic echocardiography was performed before angiography to identify right heart strain, to demonstrate indirect signs of pulmonary embolism and to exclude right heart-transit thrombi. Pulmonary angiography and embolus fragmentation were carried out in a catheter laboratory near the intensive care unit (Siemens Coroskop HIP or Siemens Polytron 1000 VR; Siemens Medical Systems, Erlangen, Germany). Before central venous access from the femoral vein, femoral or iliocaval thrombosis was excluded by vascular ultrasound ...
Pulmonary embolism is a blockage in one or more of the arteries in or leading to the lungs caused by a clot, or embolus. In almost every case, the clot originates in a deep vein in the legs, arms, or pelvis, breaks loose, and travels to the lungs.

... is the pathological occlusion of the pulmonary artery. In other words, it is when this big-caliber blood vessel gets clogged up with a thrombus (a clot of blood), microorganisms, such as filaria (parasites) or with foreign matter. The pulmonary artery is the blood vessel that carries deoxygenated blood from the heart right ventricle to the lungs. Thus, in pulmonary embolism, the blood can not be oxygenated and, as a result, the patient dies from asphyxia, that is to say, he smothers to death. ...
