Patrones imagenológicos en el diagnóstico de edema agudo de pulmón

Abstract

INTRODUCTION: Lung edema according to its etiology is classified as cardiogenic and non-cardiogenic, cardiogenic is due to the accumulation of fluid in interstitial and alveolar spaces, a consequence of the increase in cardiac filling pressures, and non-cardiogenic is evidence of fluid accumulation within of the alveolar space without increased pulmonary capillary wedge pressure. Objective: To describe the Imaging Patterns used in the diagnosis of Acute Pulmonary Edema (APE) through a review of the most up-to-date literature published in the last 4 years, using the PubMed database, to create a document that is useful for students and residents. of Medicine. According to data from the (INEC), during 2020, pulmonary edema was the eighteenth cause of mortality in Ecuador with a rate of 0.9%, of the 1,057 deaths caused, the prevalence in female patients was 39.4%, while in male patients it represented 60.6%. Conclusions: The diagnosis is based on identifying the PAD through imaging studies and with this reaching the etiology through an individual analysis and the identification of signs and symptoms, other respiratory, cardiac, as well as infectious causes must be taken into account. and toxic. Conventional chest x-ray is useful for the imaging diagnosis of lung edema in inaccessible areas, but it has been shown that lung ultrasonography shows greater diagnostic accuracy, but even so, tomography has greater clinical utility and is still the gold standard for diagnosis.
