Pulmonary embolism is considered to originate from embolization of a deep-vein thrombosis, resulting in two manifestations of one disease: venous thrombosis. However, in up to 50% of patients with pulmonary embolism no deep-vein thrombosis is found with ultrasonography. An explanation for this low proportion is currently lacking. Other imaging modalities may increase the yield of detection of d...

cardiovascular surgery, pulmonary embolism remains the most serious postoperative complication. All efforts should be directed at eliminating the factors that contribute to its incidence. Recently, there has been a revival of interest in its treatment after Cooley and BealI1 reported the first successful pulmonary embolectomy using cardiopulmonary bypass in 1961. Around the same time hyperbaric...

Paradoxical embolism is defined as a systemic arterial embolism requiring the passage of a venous thrombus into the arterial circulatory system through a right-to-left shunt. It is a relatively rare phenomenon, representing about 2% of all cases of arterial embolism. We report a case of a 79-years-old woman admitted to hospital because of dyspnea and lower left limb pain. CT scan revealed multi...

results the incidence of diagnosed thrombo-embolic complication was 32 of 1,153 admitted patients (2.8%; 95% confidence interval: 1.9 to 3.9) with a median interval of 14 days after anti-tb treatment initiation. the incidence of dvt and pte was 2% and 1%, respectively. thrombo-embolic events and dvt were more common in men than in women: 4.2% versus 1.3% (p = 0.003) and 3.5% versus 0.4%, respec...

peptide and troponin I were normal (65.5 pg/mL and < 0.01 ng/mL, respectively). Doppler ultrasound of the lower extremities showed no deep vein thrombosis, and echocardiography showed left ventricular diastolic dysfunction (grade 1) with no right-sided abnormalities. Chest CT showed embolized polymethylmethacrylate cement in the azygos system and pulmonary arteries (Figures 1 and 2, respectivel...

Embolism from the heart or the thoracic aorta often leads to clinically significant morbidity and mortality due to transient ischemic attack, stroke or occlusion of peripheral arteries. Transthoracic and transesophageal echocardiography are the key diagnostic modalities for evaluation, diagnosis, and management of stroke, systemic and pulmonary embolism. This document provides comprehensive Ame...

Patient. A case of peripheral leiomyosarcoma presenting with features of pulmonary thromboembolism is described.Discussion. Persistence of the embolus despite triple-armed thrombolytic therapy and the presence of intravascular tumour invasion suggest the rare entity of pulmonary tumour embolism from a leiomyosarcoma.

Idiopathic hypereosinophilic syndrome is characterized by prolonged eosinophilia without an identifiable underlying cause and multiple-organ dysfunction, most frequently involving the heart, the central or peripheral nervous system and the lungs. We describe a case in which a patient with asthma who had idiopathic hypereosinophilic syndrome with pulmonary involvement presented with symptoms of ...

OBJECTIVE To compare the arterial response of cases of acute and chronic embolism, seeking to associate ischemic pulmonary remodeling with progression to chronicity. METHODS Retrospective analysis of 61 necropsies of patients who died in the Instituto do Coração (31 cases of pulmonary embolism and 30 cases of acute myocardial infarction). Slides of pulmonary tissue were obtained from all case...
