Coronavirus disease (COVID-19) may predispose patients to pulmonary embolism (PE), despite standard thromboprophylaxis. Our retrospective study aimed report the prevalence of PE in with COVID-19 and severe respiratory failure (SRF) treated intermediate- full-dose enoxaparin. We analyzed data from pneumonia SRF admitted our Respiratory Intensive Care Unit (RICU) February 27 April 20, 2020. All r...

UNLABELLED The aim was to compare ventilation/perfusion SPECT lung scintigraphy (V/Q-SPECT) and computed tomography pulmonary angiography (CTPA) in patients with suspicion of pulmonary embolism (PE). MATERIAL AND METHODS This prospectively designed study included 53 patients with intermediate or high clinical probability of PE. A V/Q-SPECT and CTPA was performed on all patients. The V/Q-SPECT...

BACKGROUND The increased use of computed tomography pulmonary angiography (CTPA) is often justified by finding alternative diagnoses explaining patients' symptoms. However, this has not been rigorously examined. METHODS We retrospectively reviewed CTPA done at our center over an eleven year period (2000 - 2010) in patients with suspected pulmonary embolus (PE). We then reviewed in detail the ...

We report a case of a type A aortic dissection with extension into the main pulmonary artery through a sinus of Valsalva fistula. Echocardiography and computed tomographic angiography of the chest were performed and bicuspid aortic valve, hemopericardium, and dilatation of the aortic root were found. A Stanford type A dissection was seen, extending to the distal transverse thoracic aorta, and t...

Background: Pulmonary embolism (PE) is a common disease in the USA responsible for up to 10% of hospital mortality. Modified wells score (MWS) and D-dimer assay are used to categorize patients into high or low probability of PE. Patient with high probability need Computed tomography pulmonary angiography (CTPA), while patients with low probability and low D-dimer can safely forgo the CTPA. Obje...

Major advances in computed tomography (CT) technology, specifically multidetector CT (MDCT) with vastly improved spatial and temporal resolution,1 have led to a surge in the diagnosis of acute pulmonary embolism (PE) using computed tomography pulmonary angiography (CTPA).2–5 For persons between 35 and 74 years old, hospital diagnosis rates in 1981 for PE were 127.7 per 100 000 for blacks and 98...
