13. Capnography variables and d-dimer in patients with suspected pulmonary embolism / Variaveis capnograficas e d-dimeros em pacientes com suspeita de tromboembolismo pulmonar
Métodos para confirmar o diagnóstico de tromboembolismo pulmonar (TEP) são relativamente invasivos, de alto custo e nem sempre disponíveis. Justifica-se a busca de métodos mais acessíveis, de baixo custo, minimamente invasivos e que possam ser realizados à beira do leito. Foi objetivo deste estudo estabelecer um protocolo de triagem diagnóstica de TE

14. Alterações das concentrações plasmáticas de troponina I e de metaloproteinases 2 e 9 da matriz extracelular após embolia aguda em cães / Severity dependent increases in circulating cardiac troponin I and MMP-2 and 9 concentrations after experimental acute pulmonary thromboembolism
Making the diagnosis of acute pulmonary thromboembolism (APT) and assessing its severity is very challenging. While cardiac troponin I (CTI) levels are promising in risk stratification, no previous study has examined whether there is a linear relation between CTI levels and the severity of APT. Moreover, matrix metalloproteinases (MMPs) are involved in the p

15. Multidetector computed tomography in the evaluation of the pulmonary embolism: use of the maximum intensity projection reconstructions / Tomografia computadorizada multidetectores na avaliação do tromboembolismo pulmonar: uso de reformatações em projeção de intensidade máxima
INTRODUCTION: Multidetector computed tomography (MDCT) has been making possible the increase of the sensibility in the detection of the pulmonary embolism (PE). It is observed, however, that there is a substantial increase in the number of images and, consequently, in the time of analysis for the radiologist. A possible solution to this problem is accomplish

16. Valor do teste de dosagem do Dímero - D plasmático no diagnóstico do tromboembolismo venoso agudo / Value of measure plasmatic D Dimer test to diagnosis of the acute thrombolism venous
Introduction: The thromboembolic disease is a multicausal complex disturb with signals and symptoms that confusing itself with other diseases. Because its gravity strategies search objecting to get a faster diagnosis. The measure plasmatic D dimer test seems to be an alternative for exclusion of the diagnostic of acute venous thromboembolism. Objectives: To

17. Multiple recurrences of cardiac myxomas with acute tumoral pulmonary embolism
We report the case of a 42-year-old female with a second recurrence of cardiac myxoma. Her first diagnosis was at the age of 24 years, when cardiac tumors were withdrawn from her right ventricle and left atrium. Her first recurrence was at the age of 36 years, when tumors were removed from the left and right atria, and the right ventricle. Six years later, t

18. Plasma DNA in the diagnosis of pulmonary embolism.
To assess the diagnostic value of measuring free plasma deoxyribonucleic acid (DNA) in patients suspected of having pulmonary embolism, we prospectively assayed the plasma of 40 consecutive patients who underwent pulmonary angiography for the presence of free plasma DNA. Fifteen of them had angiographic evidence of pulmonary embolism. Of these 15 only two (1

19. Massive pulmonary embolism 3 hours after cardiopulmonary bypass. An exceeding rare case.
A 70-year-old woman underwent an aortocoronary bypass. Three hours later, she experienced severe pulmonary embolism, diagnosed by transesophageal echocardiography and followed by cardiac arrest. Resuscitation maneuvers were unsuccessful. Autopsy confirmed the diagnosis. When pulmonary embolism occurs after cardiopulmonary bypass for cardiac surgery, it usual

20. Plasma cross linked fibrin degradation products in pulmonary embolism.
Plasma concentrations of cross linked fibrin degradation products, a marker of intravascular thrombosis and fibrinolysis, were measured in 495 patients with suspected pulmonary embolism referred for ventilation-perfusion lung scanning to determine whether concentrations are increased in pulmonary embolism and their potential use in diagnosis. Lung scans were

21. Diagnosis of pulmonary embolism
NO SINGLE NONINVASIVE TEST for pulmonary embolism is both sensitive and specific. Some tests are good for “ruling in” pulmonary embolism (e.g., helical CT) and some tests are good for “ruling out” pulmonary embolism (e.g., D-dimer); others are able to do both but are often nondiagnostic (e.g., ventilation–perfusion lung scanning). For optimal effic

22. Pulmonary embolism due to compression of the inferior vena cava by a hepatic hemangioma.
We describe a 35-year-old man who had a pulmonary embolism with thrombosis of the inferior vena cava, apparently resulting from compression by a hepatic hemangioma. The diagnosis of pulmonary embolism was confirmed by pulmonary angiography; however, the hemangioma was detected only incidentally, as a hyperechoic mass, during an echocardiogram for intracardia

23. Recurrence of pulmonary embolism during anticoagulant treatment: a prospective study.
The risk of early recurrence of pulmonary embolism in patients with venous thromboembolic disease treated by anticoagulants is not well established. To determine the risk linked to contemporary proximal deep venous thrombosis, a prospective study was organised to give clinical and scintigraphic surveillance to 50 patients with angiographically proved pulmona

24. Cross sectional Doppler echocardiography as the initial technique for the diagnosis of acute pulmonary embolism.
OBJECTIVE--To determine the value of cross sectional Doppler echocardiography and derived indices of right ventricular pressure and function in the initial diagnosis of pulmonary embolism. BACKGROUND--Most deaths from acute pulmonary embolism occur because of a delay in diagnosis. Ventilation-perfusion scans are not sufficiently sensitive, whereas angiograph
