The true incidence of thrombosis and pulmonary embolism in patients requiring temporary transvenous pacing via the femoral vein in unknown. Twenty-nine patients, mean age 66.2 years (range 38-79 years) who required temporary pacing were studied by bilateral contrast venography and perfusion lung scanning after removal of the pacing catheter. The patients were subdivided into two subgroups based...

Initial studies have shown that patients infected with SARS-CoV-2 are at high risk of venous-thromboembolic events (VTE).[1][1] Post-mortem COVID-19 disease frequently show diffuse alveolar damage, pulmonary emboli and microthrombi in the lungs.[2][2] Derangement

A 61-year old Hispanic woman with a history of primary antiphospholipid syndrome with pulmonary emboli and who was status post a vena caval filter placement to prevent recurrent pulmonary emboli, presented with acute onset of right upper quadrant abdominal pain. Acute cholecystitis was diagnosed and she underwent a surgically uncomplicated cholecystectomy. The postoperative course was complicat...

via and lower extremity veins using ttmTc-albu. mm microspheres was performed in 53 patients with pulmonary emboli or venous disease. In 25 patients who underwent both contrast and RNV studies, there were no false-positive studies and one false-negative. In this series the accu racy of RNV exceeded that of Doppler alone. When the results of these two methods were combined, false-negative studie...

A patient underwent exercise testing during evaluation for unexplained dyspnea. Evidence of ventilation-perfusion mismatch was noted and subsequent testing revealed multiple pulmonary emboli. Ventilation perfusion parameters by serial exercise testing progressively improved during the course of the patient's illness but did not totally normalize. A discussion of the utility of exercise testing ...

Endocarditis is a rare presentation of group B streptococcal infection. Its association with pulmonary septic embolism was only barely studied and limited data is available up to date. Multiple septic emboli is a common complication of bacterial endocarditis, but only a few cases have been documented in relation to group B streptococcus. We present the case of an 87 year old female patient with...

We submit here an unusual case in which a user of crack cocaine presented with progressive dyspnea of subacute duration and was subsequently found to have concurrent pericardial and pleural effusions and pulmonary emboli. To our knowledge, there is only one prior case report that describes a potential causal relationship between crack cocaine and the development of a pleural effusion, via an eo...

CHEST, 71: 5, MAY, 1977 a major complication of this procedure, is reported in 10 to 50 percent of the cases.4’5 7 8 Although the indirect method of inferior vena cava interruption using an umbrella filter has resulted in significant reduction of morbidity and mortality, it is not free of complications. Because of the risks associated with different methods of inferior vena cava interruption, t...
