A good knowledge of clinical presentation and of risk factors for pulmonary embolism is mandatory to improve adequate clinical suspicion. Some recent improvements in diagnostic strategy have to be emphasized. A low D-dimer level has a good negative predictive value to rule out pulmonary embolism. Ventilation-perfusion lung scan is the most often used imaging technique. In case of non diagnostic...

Abstract Thrombosis in general, and especially venous thromboembolism (VTE) is one of the most common complications associated with COVID-19 infection. We present a 48 years old male patient dyspnea severe multisite post Covid-19 disease thrombotic complications, pattern never seen before, that includes both ventricles, pulmonary arteries peripheral vein involvement, assessed by echocardiograph...

The primary pulmonary artery sarcomas are rarely seen, can imitate pulmonary thromboembolism. The prognosis of patients with pulmonary artery sarcomas is dependent on its early and accurate diagnosis. Placed below is a description of a case of a 51-year-old man presented with dry cough and breathlessness was initially thought to have a Koch's lesion. AKT was given but the patient did not improv...

This paper proposes an efficient customized level set algorithm to segment Pulmonary Artery (PA) tree in 3D pulmonary Computed Tomography Angiography (CTA) images. In this algorithm, to reduce the search area the lung regions from the original image are first segmented and the heart region is extracted by selecting the regions between the lungs. A pre-processing algorithm based on Hessian matri...

massive hemoptysis is one of the most important respiratory emergencies and pulmonary infiltrating diseases are among the rare causes of hemoptysis. bronchial artery embolization (bae) is a safe and effective treatment in these patients. our case was a 45 years old woman with a 7 year history of hodgkin's lymphoma who presented with massive hemoptysis of 20 days duration. ct scan revealed prebr...

Abstract Background The prevalence of coronary artery fistula (CAF) among Egyptian population is increasing due to widespread availability CT angiography using high-end scanners. purpose this observational study was determine the incidence and types CAF detected during routinely performed angiography. Results Among 2263 retrospectively evaluated studies, only in 17 (0.75%) patients with proxima...

Rhabdomyosarcoma (RMS) is an uncommon type of soft-tissue malignancy which mainly influences children. Primary pulmonary RMS (PPR) is extremely uncommon. Here, we describe a case of PPR complicated by pulmonary artery extensive embolism. A 41-year-old Chinese woman characterized of repeating cough complained of chest congestion. Despite first diagnosis of pulmonary infection, antibiotic therapy...

embolism (PE) is two to three patients for every 1,000 who present with nonspecific clinical signs and symptoms (1). In patients with a malignant tumor, the incidence of PE is increased by 4-6 times compared to the general population who present with nonspecific clinical signs and symptoms. The risk of thrombus formation increases even more in patients who are receiving chemotherapy and have an...

BACKGROUND Helical computed tomography (CT) techniques for the diagnosis of pulmonary embolism have been refined over the past decade. Helical CT is widely used in the diagnosis of pulmonary embolism despite the lack of well-designed trials supporting this approach. Although helical CT correlates well with pulmonary angiography in detecting central emboli, critics argue that it misses more dist...
