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...

Patients presenting to the emergency department with dyspnea after recent coronary artery bypass graft (CABG) present a unique diagnostic challenge. There have been no previous reports in the literature of a patient with bilateral pulmonary emboli (PE) and bilateral pneumothoraces after CABG. We describe an adult male who presented with shortness of breath after recent CABG. He was found to hav...

Subendocardial hydatid . cysts may rupture into the right or left chamber of the heart to produce pulmonary or systemic embolisation.' Few cases have been reported,2 and I believe that this case is the first to be reported in the United Kingdom in which a primary hydatid cyst in the interventricular septum caused multiple emboli in the pulmonary and systemic arterial circulation. The electrocar...

USING transesophageal echocardiography, echogenic material can be shown in the right ventricle during many orthopedic procedures. Recently, transcranial Doppler–recorded microembolic signals have been described during femoral fracture fixation, suggesting that medullary pressurization may be associated with systemic microembolism and pulmonary fat and marrow emboli. Although reamed, locked intr...

Right heart thrombus in transit (RHTT) is a rare, severe form of venous thromboembolism that carries a high mortality rate. The optimal treatment for RHTT has not been well established. Thrombolysis is a therapeutic modality for RHTT but carries the risk of bleeding complications including intracranial hemorrhage. Low-dose thrombolysis has been shown to be effective in treating submassive pulmo...

Lemierre syndrome, which can result from a recent oropharyngeal or odontogenic infection, is characterized by clinical or radiographic signs of thrombosis of the internal jugular vein, distant infected emboli and the presence of anaerobic pathogens, usually Fusobacterium necrophorum. The septic emboli resulting from the infected thrombophlebitis of the internal jugular vein give the syndrome it...

BACKGROUND Studies aimed at assessing whether the emboli lodged in the central pulmonary arteries carry a worse prognosis than more peripheral emboli have yielded controversial results. AIMS To explore the impact on survival and long-term prognosis of central pulmonary embolism. PATIENTS AND METHODS Consecutive patients diagnosed with acute symptomatic pulmonary embolism by means of compute...

Paradoxical cerebral emboli from cardiac and pulmonary sources are well described in the peer-reviewed literature. We outline a case with a hepatic etiology and describe diagnostic and management options. Though this paper represents the first documentation of such, we believe that transpulmonary shunting with concurrent paradoxical cerebral microemboli is more prevalent than recognized. We int...

A 30-year-old female with no significant past medical history was referred to our facility with sudden onset of shortness of breath. She had a low clinical probability for pulmonary thromboembolism and a computed tomography angiogram showed enlarged pulmonary arteries but no in situ thrombi. She developed recurrent episodes of hypotension and hypoxia, and was transferred to the intensive care u...
