Acute pulmonary thromboembolism is a catastrophic event, especially for hospitalized patients. The prognosis of pulmonary thromboembolism depends on the degree of pulmonary arterial occlusion. The mortality of massive pulmonary embolism is reportedly as high as 25% without cardiopulmonary arrest and 65% with cardiopulmonary arrest. In patients with unstable hemodynamics due to pulmonary thrombo...

Pulmonary thromboembolism is a life-threatening cardiovascular condition. The mortality rate is high in its current management. Besides supportive treatments, systemic thrombolysis and surgical thrombectomy play important roles in the comprehensive management of pulmonary embolism (PE). The percutaneous catheter-based rheolytic thrombectomy is a promising alternative for management of massive p...

OBJECTIVES To assess the feasibility of performing pulmonary angiography using MRI with contrast enhancement in patients with pulmonary vascular disease. METHODS We present our experience in ten individuals, two controls and eight patients who underwent the exam after injection of a gadolinium-based contrast agent on a 1 Tesla MR scanner using a time-of-flight sequence and breath-holding duri...

Pulmonary arteriovenous malformations (PAVMs) are abnormal connections of the pulmonary artery to the pulmonary vein, which bypass the normal pulmonary capillary bed.1 This leads to a right-to-left shunt the diameter of the feeding vessel. The normal pulmonary capillary bed measures only 8 to 10 mcm in diameter and serves not only to oxygenate blood but also to filter small thrombi and bacteria...

Right heart thrombus represents a mobilized deep venous thrombosis that is lodged temporarily in the right atrium and ventricle, and is often referred to as "emboli in transit." Floating right heart thrombus is an uncommon but life-threatening condition, and usually coexists with an already massive pulmonary embolism. The presence of floating right heart thrombus appears to substantially increa...

This study correlated levels of activated fibrinolysis with the presence, extent, and rate of resolution of angiographically documented pulmonary emboli. Pulmonary emboli demonstrable by angiography were associated with detectable fibrin split products in the serum of 24 of 25 patients. In the absence of increased fibrin split products, pulmonary emboli large enough to be demonstrated by angiog...

Twenty-five patients with proven pulmonary emboli were followed for at least 20 weeks with serial scans and, in select cases, angiograms to determine the factors influencing the rate of resolution. Fifteen patients showed complete resolution at some time during the observation period. Five of these 15 patients experienced recurrent embolic episodes either before or after complete resolution. Th...

INTRODUCTION Acute pulmonary embolism has varied presentations ranging from asymptomatic, incidentally discovered emboli to massive embolism, causing immediate death. Tumor embolism is a rare but unique complication of malignancies. This uncommon catastrophe of a malignant tumor in a young patient, culminating as a pulmonary embolism, is being reported for the first time. CASE PRESENTATION A ...
