Obstructive sleep apnoea is a risk factor for pulmonary embolism. Elevated D-dimer levels and other biomarkers are associated with recurrent pulmonary embolism. The objectives were to compare the frequency of elevated D-dimer levels (>500 ng·mL(-1)) and further coagulation biomarkers after oral anticoagulation withdrawal in pulmonary embolism patients, with and without obstructive sleep apnoea,...

Pulmonary embolism is a very dangerous difficult-to-detect medical condition. To diagnose pulmonary embolism, medical practitioners combine indirect signs of this condition into a single score, and then classify patients into low-probability, intermediate-probability, and high-probability categories. Empirical analysis shows that, when we move from each category to the next one, the probability...

The incidence of venous thromboembolism after major trauma has been estimated to be as high as 60%, despite appropriate prophylaxis. Pulmonary embolism is associated with deep venous thrombosis and also with significant rates of morbidity and mortality. This study examined risk factors for pulmonary embolism among patients with pelvic and lower-extremity fractures in the National Trauma Data Ba...

Anticoagulantis an agent that is used to prevent the formation of blood clots. Anticoagulants, such as heparin or warfarin work on chemical reactions in the body to lengthen the time it takes to form a blood clot. Heparin the anticoagulant drug that is used to prevent blood clots from forming during and after surgery and to treat various heart, lung, and circulatory disorders in human body. Hep...

BACKGROUND The limitations of the current diagnostic standard, ventilation-perfusion lung scanning, complicate the management of patients with suspected pulmonary embolism. We previously demonstrated that determining the pretest probability can assist with management and that the high negative predictive value of certain D -dimer assays may simplify the diagnostic process. OBJECTIVE To determ...

Background. Pulmonary embolism is a common and potentially lethal condition. Most patients who die from massive pulmonary embolism do so within the first few hours of the event. The clinical manifestations of pulmonary embolism are nonspecific, which makes the diagnosis difficult. Case Report. We present a case of massive pulmonary embolism presenting as an acute surgical abdomen that underwent...

INTRODUCTION Coexistence of pulmonary embolism and systemic arterial embolism suggest the diagnosis of paradoxical embolism which suggests the presence of intracardiac defects such as patent foramen ovale (PFO). CASE PRESENTATION A 42 year old man was found to have a paradoxical embolism in the systemic arterial circulation, in the setting of pulmonary embolism and deep vein thrombosis (DVT) ...

BACKGROUND To investigate the incidence of pulmonary embolism and risk factors for this condition after obstetric and gynecologic surgery, as well as the efficacy of intermittent pneumatic compression. METHODS A total of 6,218 patients operated at Keio University Hospital excluding obstetric or infertility-related surgery and uterine cervical conization were evaluated retrospectively to deter...

Major pulmonary embolism occurring insidiously over several weeks (subacute massive pulmonary embolism) has a high mortality and may not respond well to standard anticoagulant or thrombolytic treatment. A priming dose of plasminogen was used to enhance thrombolysis produced by a streptokinase infusion in five consecutive patients with subacute massive pulmonary embolism. In each patient a drama...

The diagnosis of pulmonary embolism may be confounded by a clinical presentation that is often subtle or atypical. Therefore pulmonary angiography, although invasive, has been widely used to prove pulmonary embolism. The aim of this review is to discuss the value of non-invasive techniques, such as lung scan and chest computed tomography scan, in the diagnosis of pulmonary embolism. Ventilation...
