  3. Diagnostic algorithm: Pulmonary embolism

    show more
    Description: A diagnostic algorithm for pulmonary embolism (estimated frequencies of test results and associated prevalences of pulmonary embolism for a hypothetical cohort of 1000 outpatients) [1]. If a very sensitive D-dimer assay is used, it can be the first test performed: a negative result excludes pulmonary embolism regardless of clinical assessment category and a positive test can be followed by a ventilation–perfusion scan [2]. A ventilation–perfusion scan can be performed as the initial test without using clinical assessment of the probability of pulmonary embolism as part of the diagnostic process [3]. Pulmonary angiography or helical CT may be considered if the clinical assessment of pulmonary embolism probability is low, particularly if a D-dimer test has not been done [4]. Additional testing (e.g., helical CT, bilateral venography) may be considered if overall assessment suggests a high probability of pulmonary embolism (e.g., 50%–80%), symptoms are severe or cardiopulmonary reserve is poor [5]. Venography should be considered if there is an increased risk of a false-positive ultrasound result (e.g., previous venous thromboembolism, equivocal ultrasound findings, preceding findings suggest low probability of pulmonary embolism [e.g., ≤ 10%]) [6]. It is reasonable not to repeat ultrasound testing, or to do only 1 more ultrasound after 1 week, if preceding findings suggest a low probability of pulmonary embolism (e.g., ≤ 10%) [7]. If helical CT is used in place of ventilation–perfusion lung scanning: (i) intraluminal filling defects in segmental or larger pulmonary arteries are generally diagnostic for pulmonary embolism; (ii) all other findings (i.e., a normal CT scan or intraluminal filling defects confined to the subsegmental pulmonary arteries) are nondiagnostic and can be managed as shown for a nondiagnostic lung scan.

  4. CT (chest), (axial), Adult Male Pulmonary Embolism with Right Heart Strain

    show more
    Description: There are occlusive pulmonary emboli within the left and right main pulmonary arteries. The thrombus within the right main pulmonary artery extends into the right lower lobe segmental arteries. The heart is slightly enlarged with enlargement of the ventricle deviating the intraventricular septum indicating right heart strain. Additionally the main pulmonary artery measures approximately 3.2 cm in diameter indicating pulmonary arterial hypertension. Lung windows demonstrates patchy consolidation at the right lower lobe peripherally which represents infarcted lung parenchyma. There is a small right-sided pleural effusion. The left lung is clear. There is no evidence of enlarged hilar or mediastinal lymphadenopathy. The visualized portions of the upper abdominal viscera including the adrenal glands are normal. Evaluation of bone windows demonstrate no abnormality. IMPRESSION: Bilateral central pulmonary emboli with left lower lobe pneumonia infarction.
