Resumo(s)
PTE (Pulmonary Thromboembolism) is the third most common cause of cardiovascular death, with more than 600,000 cases per year in the US. This pathology has a wide spectrum of presentations and severity, with some patients experiencing shock, requiring urgent thrombolysis, while others can be safely treated on an outpatient basis with anticoagulation treatments alone (John, Marti Poletti, Perrier, 2014).
The degree of pulmonary arterial obstruction and the previous cardiorespiratory status determine the hemodynamic consequences of PTE, the elevation of pulmonary pressure is insignificant until the obstruction of the pulmonary arterial bed is greater than 30–50%, whereby above this threshold it increases rapidly, causing an elevation of pulmonary vascular resistance and consequently significant pulmonary hypertension with enlargement of the proximal arterial vessels, resulting in an afterload on the right ventricle and therefore its dilation. (Bryce, Perez-Johnston, Bryce, Homayoon, & Santos -Martin, 2019; John, et al., 2014).
The main objective is to assess the anatomical changes that may be present in patients diagnosed with PTE. In order to be able to reach the main objective of the work and answer the pre-defined research questions, there was a need to also define specific objectives, which consisted of analyzing which alterations were the most evidence of the presence of PTE; relate verifiable anatomical alterations through pulmonary Angio-CT with gender; relate verifiable anatomical alterations through pulmonary Angio-CT with age; to relate the curvature of the interventricular septum and the dilation of the right ventricle and also to relate the dilation of the pulmonary artery trunk and the dilation of the right ventricle.
