ReviewClinical and radiological diagnosis of pulmonary thromboembolism.
Pulmonary thromboembolism has poorly specific clinical symptomatology, which increases the diagnostic suspicion, multiplying the number of patients who will need to undergo imaging tests to confirm the diagnosis. In recent years, pulmonary angiography using multidetector scanners (CT angiography) has been the most widely used imaging test due to its availability and accuracy, which exceeds that of lung ventilation-perfusion (V/Q) scintigraphy. ⋯ We therefore need to base our approach on previously validated strategies that, taking into account the clinical probability and using highly sensitive diagnostic tests such as D-dimer, will enable us to exclude many patients from undergoing this imaging test. In this article, we review the diagnostic techniques and strategies that are applied for diagnosing pulmonary thromboembolism in hemodynamically stable and unstable outpatients, hospitalised patients, patients with a history of venous thromboembolism and pregnant women.

The purpose of this guide is to suggest, based on the available clinical evidence, the prevention measures for venous thromboembolism during pregnancy, childbirth and postpartum in expert recommendations and international guidelines. Venous thromboembolism is a cause of maternal death, and it is therefore important to consider those situations in which the risk is greater and for which women should undergo preventive treatment. ⋯ Low-molecular-weight heparin is the treatment of choice for these women. Prophylaxis might be necessary during the antenatal or postnatal period, and the duration and indication will vary depending on the risks and benefits.
