CONTEXT AND OBJECTIVE The location of embolism is associated with clinical findings and disease severity in cases of acute pulmonary embolism. The level of gamma-glutamyl transferase increases under oxidative stress-related conditions. In this study, we investigated whether gamma-glutamyl transferase levels could predict the location of pulmonary embolism. DESIGN AND SETTING Hospital-based cr...

Introduction: Pulmonary embolism (PE) is a common lethal disease that its clinical symptoms may be seen in many other diseases. Computed tomography pulmonary angiography (CTPA) is a valuable diagnostic modality for detection of PE. In addition, it can accurately detect the other diseases with clinical symptoms similar to PE. The aim of this study is to evaluate the frequency of PE and nonemboli...

Although stroke volume may decrease markedly after acute pulmonary embolism, left ventricular end-diastolic pressure (LVEDP) usually changes very little, which suggests that compliance or contractility or both are reduced. To test the hypothesis that the altered LV function during pulmonary embolism is primarily due to reduced preload mediated by increased pericardial constraint, hemodynamics a...

A blind assessment of abnormalities of pulmonary scintiscans in patients with pulmonary emboli and other clinical conditions showed that there was no abnormality specific for pulmonary embolism. However, a normal lung scan virtually excluded pulmonary embolism and an area, or areas, of absent perfusion was confirmatory evidence of embolism, without infarction, if the chest radiograph was normal...

UNLABELLED Background Context. Vertebroplasty is a minimally invasive procedure most commonly used for the treatment of vertebral compression fractures. Although it is relatively safe, complications have been reported over time. Among those complications, massive cement pulmonary embolism is considered a rare complication. Here we report a case of massive diffuse cement pulmonary embolism follo...

BACKGROUND The evaluation of right ventricular (RV) dysfunction by echocardiography is one of the most important established determinants of the prognosis of acute pulmonary embolism. The aim of the study was to investigate possible association between diameter of right descending pulmonary artery on chest X-rays and RV dysfunction by echocardiography in hemodynamically stable pulmonary embolis...

In cases of pulmonary embolism, the visualization of a free-floating right heart thrombus on conventional transthoracic echocardiography is extremely rare. Even rarer is an echocardiographic recording of migration of a free-floating clot from the right heart into the pulmonary vasculature leading to pulmonary embolism. We present a unique case of an elderly man who presented with dyspnoea, in w...

Arterial hypoxemia is a common finding in acute pulmonary embolism, and its severity is generally assumed to be proportional to the extent of pulmonary artery obstruction. We studied blood gases (during room air breathing and 100% oxygen breathing) and hemodynamic data is seven patients with massive pulmonary embolism and circulatory failure. All measurements were made before and 30 minutes aft...

BACKGROUND Symptomatic pulmonary embolism constitutes a significant risk following abdominal flap breast reconstruction. Reported rates vary from 0 to 6 percent. The authors assessed risk factors associated with symptomatic pulmonary embolism and constructed a prediction model to identify high-risk patients. METHODS Patients undergoing deep inferior epigastric perforator or transverse rectus ...

CONTEXT The clinical validity of using computed tomography (CT) to diagnose peripheral pulmonary embolism is uncertain. Insufficient sensitivity for peripheral pulmonary embolism is considered the principal limitation of CT. OBJECTIVE To review studies that used a CT-based approach to rule out a diagnosis of pulmonary embolism. DATA SOURCES The medical literature databases of PubMed, MEDLIN...
