Only 4-6% of children with renal tumor show inferior vena caval or right atrial infiltration at presentation. Tumor emboli are even rarer, and so far, sudden death as the presenting symptom has only been described at presentation in Wilms' tumor in eight cases. We report a unique case of Wilms' tumor that presented with small pulmonary emboli and immediately after as that was diagnosed before d...

BACKGROUND Tissue factor (TF) is the initiation factor of the extrinsic coagulation pathway, and plays a critical role in the process of thrombosis. This study aimed to investigate the expression of TF and to explore their clinical effect on the pulmonary artery after acute pulmonary thromboembolism. METHODS Thirty-four Japanese white rabbits (Level II animals) supplied by Tianjin Medical Uni...

A 50-year-old male with sudden syncope and witnessed seizure activity was discovered to have pulmonary emboli. Although he denied shortness of breath, d-dimer testing was positive and a ventilation-perfusion scan was positive for bilateral pulmonary emboli; cardiac ECHO also confirmed elevated right ventricular pressures. The literature on this unusual presentation for seizures as the initial m...

Orthopaedic patients are at particularly high risk for pulmonary embolism. There has been a trend recently toward overdiagnosis of pulmonary embolism; thus, evaluation of the nature of a clinically relevant pulmonary embolism is needed, as is assessment of the timing, risks, and outcomes of therapeutic anticoagulation in surgical patients. Recent literature shows the incidence of pulmonary embo...

Although the syndrome of "subacute cor pulmonale" caused by multiple tumour emboli to the pulmonary arteries has been well-described,' few reports have recorded detailed haemodynamic measurements from the pulmonary circulation in this setting. We describe a woman with known metastatic breast carcinoma who developed dyspnoea of hidden origin. Perfusion lung scanning and pulmonary angiography wit...

Periprostatic or paravaginal venous thromboses are rarely considered clinically as sites of clot origin in patients with pulmonary thromboembolism. The majority of emboli have been demonstrated to originate in the veins of the legs. This report raises awareness of pelvic vein thrombosis as a potential source of pulmonary embolism that is rarely considered or detected clinically, and which usual...

I MPRESSIVE pathologic evidence has accumulated that suggests that recurrent showers of small pulmonary emboli are commonly undetected clinically.1 3 The eventual development of obstructive pulmonary hypertension and cor pulmnonale in some cases is well known, but effective therapy of this late stage of the disease is not available. It has been reported, however, that prompt treatment can resul...
