BACKGROUND Hyperdense middle cerebral artery sign is an appearance of the middle cerebral artery on non-contrast-enhanced computed tomography. Embolic occlusion of the pulmonary arterial system is referred to as pulmonary embolism. When pulmonary embolism coexists with a patent foramen ovale, increased pressure in the right atrium may result in widening of the foramen and consequently, cause se...

Syncope is the state of lack of consciousness and temporal loss of postural tone. Syncope might be in association with a variety of benign and life-threatening conditions. Pulmonary embolism (PE) has been shown to be associated with syncope in 13-30 percent of cases. This article presents a novel case report of PE whom syncope was his only manifestation.

This is a preliminary report of 28 patients with ulcerative colitis who we surgically treated with "J" pouch endorectal pull-through operation from 1978 to 1996. All patients are continent with a median stool frequency of 4 times per day, no night soilage. low postoperative complications and one mortality due to pulmonary embolism.

Untreated massive pulmonary embolism is associated with a high mortality. Pulmonary embolectomy has been largely superceded by thrombolytic therapy, but there are cases in which pulmonary embolectomy remains the treatment of choice. We present three case reports and discuss the merits of the various treatments available for massive pulmonary embolism. The primary treatment of massive pulmonary ...

The high-probability ventilation-perfusion lung scan is accepted as supportive of pulmonary embolism and often negates further diagnostic evaluation; however, there are processes that mimic the clinical presentation and radiographic findings of pulmonary emboli, including a unilateral segmental or greater perfusion defect. We present the findings in a patient whose presentation and ventilation-...

Although pulmonary artery angiosarcoma is rare, it can be misdiagnosed as pulmonary embolism because of its similar clinical and diagnostic features. The diagnosis is often delayed and the misdiagnosis brings unnecessary treatment. Because we made a wrong diagnosis of pulmonary artery angiosarcoma as an acute pulmonary embolism, we did thrombolytic therapy which could be dangerous to the patien...

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...

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...
