a 22-year-old woman presented with acute left-sided pleuritic chest pain and dyspnea 6 days after surgery for revision of the stenotic central aortopulmonary shunt. she had a history of tetralogy of fallot (tof), pulmonary valve stenosis, ventricular septal defect and major aortopulmonary collateral artery. her waterston shunt was placed when she was 5 years old and stented and re-dilated after...

pulmonary embolism is considered as a great masquerader due to its frequent nonspecific signs and symptoms. typically pulmonary embolism is under-diagnosed or over-diagnosed. in this study a patient with pulmonary embolism is reported in which the patient exhibited two unusual manifestations namely; right upper quadrant abdominal pain and st-t elevation in anterior precordial leads. due to the ...

background: considering the importance of using more appropriate imaging technique for accurate diagnosis of pulmonary thromboembolism (pte) with less side eff ects, we aimed to evaluate the quality of pulmonary 64-multidetector computed tomographic (mdct) angiography in pregnant and postpartum women with suspected pte in isfahan. materials and methods:in this descriptive study, radiological fi...

OBJECTIVES To evaluate the feasibility of CT pulmonary angiography for identification of naturally occurring pulmonary thromboembolism in dogs using predefined diagnostic criteria and to assess the ability of echocardiography, cardiac troponins, D-dimers and kaolin-activated thromboelastography to predict the presence of pulmonary thromboembolism in dogs. METHODS Twelve dogs with immune-media...

This review was undertaken with an eye of providing an evidence-based guide for internists in the utilization of the various techniques in the diagnosis of pulmonary emboli. Pulmonary angiography represents a group of tests that are used alone or in combination to evaluate for the presence of pulmonary emboli (PE)† and encompasses computed tomography (CT) pulmonary angiography (which is noninva...

During the 1990s, computed tomography (CT) and magnetic resonance (MR) imaging underwent extensive technological advancement and expanded clinical use in patients with venous thromboembolic disease, particularly with regard to evaluation of the pulmonary vasculature. In many institutions, helical (spiral) CT pulmonary angiography has become the initial imaging study of choice to evaluate patien...

STUDY OBJECTIVE Ready availability of computed tomography (CT) angiography for evaluation of pulmonary embolism in emergency departments (EDs) is associated with a dramatic increase in the number of CT angiography tests. The aims of this study are to determine whether a validated prediction algorithm embedded in a computerized decision support system improves the positive yield rate of CT angio...

INTRODUCTION Although the advent of multi-detector row computed tomography (CT) has enabled better visualization of subsegmental pulmonary (SSP) arteries, SSP embolism is of uncertain clinical significance. We aimed at answering the following questions: Is spiral CT an accurate method to detect SSP embolism? How are subsegmental perfusion defects managed in outcome studies including spiral CT? ...
