OBJECTIVE We tested whether correlation between embolism area and pulmonary arterial pressure may serve as an indicator of pulmonary arterial hypertension in patients with acute pulmonary thromboembolism. PATIENTS AND METHODS In total, 204 patients who underwent spiral computed tomography (CT) pulmonary angiography and ultrasonic cardiogram were enrolled. The patients were stratified accordin...

OBJECTIVE Pulmonary embolism is a major cause of maternal death. The work up for suspected pulmonary embolism is complex, with many potential diagnostic options. We performed a cost analysis to evaluate which of several diagnostic strategies was the most cost-effective with the least number of deaths from pulmonary embolism. STUDY DESIGN We created a decision tree to evaluate the following st...

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 ...

A pulmonary embolism and cerebral infarction are the second and third most common acute cardiovascular diseases after a myocardial infarction. Early diagnosis and appropriate management are important clinical challenges. In this case, a fatal pulmonary embolism and extensive cerebral infarction caused cardiac arrest during spinal anesthesia for total hip replacement surgery. Transesophageal ech...

Pneumatic lithotripsy is a minimally invasive technique mainly for the treatment of urinary staghorn stones. Previous literatures have reported some therapeutic complications during or after this procedure, but calculi embolism has not been mentioned before.We report here a fatal case of calculi-induced pulmonary embolism in an adult woman who underwent pneumatic lithotripsy. An autopsy did not...

Background—Heart diseases increase the risk of arterial embolism; whether they increase the risk of pulmonary embolism without peripheral venous thrombosis is less certain. Methods and Results—We conducted a nationwide, population-based case-control study in Denmark using patients diagnosed with pulmonary embolism and/or deep venous thrombosis between 1980 and 2007. We computed odds ratios to e...

Pulmonary embolism carries a significant morbidity and mortality. Metastatic choriocarcinoma presenting as pulmonary embolism is a rare event. Here, we report a case of a 25-year-lady with a history of worsening shortness of breath for 4 months who was treated as a case of pneumonia and tuberculosis. Owing to the worsening condition, she had a contrast enhanced computed tomography (CECT) chest ...

CONTEXT Ventilation-perfusion (V(dot)Q(dot) lung scanning and computed tomographic pulmonary angiography (CTPA) are widely used imaging procedures for the evaluation of patients with suspected pulmonary embolism. Ventilation-perfusion scanning has been largely replaced by CTPA in many centers despite limited comparative formal evaluations and concerns about CTPA's low sensitivity (ie, chance of...

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...
