Improving efficiency of the diagnostic management of pulmonary embolism

Pulmonary embolism (PE) refers to a blood clot in the pulmonary artery or one of its branches, which is most commonly originating from deep venous thrombosis (DVT) of the legs or pelvis. Venous thrombo-embolism (VTE) encompasses both pulmonary embolism (PE) and deep venous thrombosis (DVT). VTE is the third most frequent cardiovascular disease and it is a major cause of mortality, morbidity and chronic disease and disability. In Europe, it affects 430,000 patients each year and worldwide the overall annual incidence is 100-200 per 100,000 inhabitants. The diagnostic process of patients with suspected PE is challenging due to the non-specific symptoms and clinical presentation. Integrated diagnostic algorithms including validated clinical decision rules, high sensitive D-dimer tests and imaging tests such as computed tomography pulmonary angiography (CTPA) may guide the clinician, and close adherence to the diagnostic algorithm is of crucial importance for the clinical outcome of patients with suspected PE. The focus of this thesis is the diagnostic management of patients with suspected PE. LUMC / Geneeskund
