Although pulmonary artery angiosarcoma is rare, it can be misdiagnosed as pulmonary embolism because of its similar clinical and diagnostic features. The diagnosis is often delayed and the misdiagnosis brings unnecessary treatment. Because we made a wrong diagnosis of pulmonary artery angiosarcoma as an acute pulmonary embolism, we did thrombolytic therapy which could be dangerous to the patien...

Abstract Background Pulmonary embolism (PE) is a common condition with considerable morbidity and mortality; it more often diagnosed post-mortem by pathologists than in vivo clinicians. Prompt accurate diagnosis difficult because PE may be clinically silent, the symptoms are vague nonspecific, addition, there no definitive, non-invasive diagnostic test to establish its diagnosis. The aim of thi...

Acute pulmonary embolism remains a common cause of mortality. Early diagnosis and appropriate risk stratification is necessary to individualize treatment strategy. Computed tomography scan of the pulmonary arteries is routinely used to diagnose acute pulmonary embolism and in some cases is useful to assess right ventricular dilation. In patients with acute pulmonary embolism, right ventricular ...

BACKGROUND Pulmonary embolism continues to be a significant cause of death. The aim was to derive and validate a risk prediction model for in-hospital death after acute pulmonary embolism to identify low risk patients suitable for outpatient management. METHODS A confirmed acute pulmonary embolism database of 1,426 consecutive patients admitted to a tertiary-center (2000-2012) was analyzed, w...

RATIONALE Clinical probability assessment is a fundamental step in the diagnosis of pulmonary embolism. OBJECTIVES To develop a predictive model for pulmonary embolism based on clinical symptoms, signs, and the interpretation of the electrocardiogram. METHODS The model was developed from a database of 1,100 patients with suspected pulmonary embolism, of whom 440 had the disease confirmed by...

To determine the sensitivities and specificities of ventilation/perfusion lung scans for acute pulmonary embolism, a random sample of 933 of 1493 patients was studied prospectively. Nine hundred thirty-one underwent scintigraphy and 755 underwent pulmonary angiography; 251 (33%) of 755 demonstrated pulmonary embolism. Almost all patients with pulmonary embolism had abnormal scans of high, inter...
