Neste artigo é feita revisão acerca da importância do diagnóstico de tromboembolismo pulmonar, bem como os métodos de imagem disponíveis, com ênfase na tomografia computadorizada com dupla energia. Nos últimos anos, houve o desenvolvimento da tomografia computadorizada com dupla energia e essa ferramenta tem se mostrado promissora para avaliação da perfusão pulmonar por meio do mapa de iodo. Os métodos de imagem fornecem o diagnóstico definitivo, sendo a tomografia computadorizada o método mais utilizado atualmente. Devido ao quadro clínico e fatores de risco inespecíficos, o diagnóstico de tromboembolismo pulmonar torna-se um desafio. In this article, we will review the importance of diagnosing pulmonary thromboembolism, as well as the imaging methods employed, primarily dual-energy computed tomography.Ī acurácia no diagnóstico de tromboembolismo pulmonar é essencial para reduzir a morbimortalidade causada por esta enfermidade. The recent development of dual-energy computed tomography has provided a promising tool for the evaluation of pulmonary perfusion through iodine mapping. Currently, the imaging method most commonly used in the evaluation of pulmonary thromboembolism is computed tomography. Imaging methods provide the definitive diagnosis. The diagnosis of pulmonary thromboembolism is challenging because of the nonspecific nature of the clinical profile and the risk factors. The accurate diagnosis of pulmonary thromboembolism is essential to reducing the morbidity and mortality associated with the disease.

Radiologists need to know the normal findings in these patients so they can quickly identify possible complications, most of which can be diagnosed with intravenous contrast-enhanced MDCT.Pulmonary thromboembolism: new diagnostic imaging techniquesĪutho(rs): Julia Noschang 1 Marcos Duarte Guimarães 2 Diogo Fábio Dias Teixeira 3 Juliana Cristina Duarte Braga 3 Bruno Hochhegger 4 Pablo Rydz Pinheiro Santana 5 Edson Marchiori 6 The rate of complications in bariatric surgery is high and the associated mortality is not negligible. All of these complications were diagnosed with intravenous contrast-enhanced MDCT, except one, which required a barium transit study. We reviewed 155 cases and found 24 complications in 22 patients: 16 early complications (7 intraperitoneal hematomas, 5 anastomotic dehiscences, 2 intestinal obstructions, and 2 external hernias) and 8 late complications (3 internal hernias, 3 intestinal perforations, and 2 marginal ulcers). We classified complications into early complications (appearing within 30 days of the intervention) and late complications. We retrospectively studied all patients who underwent gastric bypass or sleeve gastrectomy at our center during 2013 or 2014. To review the complications of bariatric surgery and their diagnosis with intravenous contrast-enhanced multidetector computed tomography (MDCT). Deben reconocerse los hallazgos normales en estos pacientes para identificar rápidamente las posibles complicaciones, diagnosticadas en su mayoría mediante TCMDcCIV. La tasa de complicaciones en la cirugía bariátrica es elevada y su mortalidad no es despreciable. Todas las complicaciones se diagnosticaron mediante TCMDcCIV, excepto una que requirió un tránsito baritado. Se revisaron 155 casos y se diagnosticaron 24 complicaciones en 22 pacientes: 16 precoces (7 hematomas intraperitoneales, 5 dehiscencias anastomóticas, 2 obstrucciones intestinales y 2 hernias externas) y 8 tardías (3 hernias internas, 3 perforaciones intestinales y 2 úlceras en boca anastomótica). Las complicaciones se dividieron en precoces (durante el primer mes) y tardías. Material y métodosĮstudio retrospectivo de los pacientes intervenidos mediante by-pass gástrico o gastrectomía tubular en nuestro centro durante 2013 y 2014. Revisar las complicaciones de la cirugía bariátrica y su diagnóstico mediante tomografía computarizada multidetector con contraste intravenoso (TCMDcCIV).
