We describe the case of a 19-year-old woman with no significant medical history who developed progressive right-sided neck pain and palpitations one month following pregnancy complicated by preeclampsia. Family was for unprovoked deep vein thrombosis (DVT) pulmonary embolism (PE) in her father at age 44. Systemic examination revealed mild swelling right upper extremity on palpation. Computed to...

Vena caval filters: keeping big clots down Pulmonary emboli are usually unexpected, and research has concentrated on eliminating the source, deep vein thrombosis .' Once a deep vein thrombosis has developed we rely heavily on anticoagulation, even though evidence that this works is poor.2 Surgeons have thus been attracted by the idea of trapping clots in the leg or pelvic veins, where they are ...

Quantification of pulmonary emboli has become important in assessing the results of thrombolytic therapy and in following the natural history of thromboemboli. This study evaluated angiography as a quantitative procedure by comparing sequential changes in emboli of known size and weight with alterations on angiograms. Twenty-four aged thrombi formed in vivo were embolized intact into 12 recipie...

Pulmonary embolism is now known to be a common disorder, but it is often difficult to diagnose, particularly when recurrent embolization gradually leads to the development of obstructive pulmonary hypertension. The abnormalities of pulmonary function produced by emboli have been the subject of several recent reports ; many of these studies, however, have been performed in the acute phase follow...

Pulmonary emboli seldom recur, and when recurrence does occur it is not associated with permanent sequelae unless there is progressive pulmonary arterial hypertension. Five patients with clinical and perfusion lung scan evidence of recurrent pulmonary embolism presented with abnormal cardiac rhythms without evidence of progressive pulmonary hypertension. Twenty-four-hour ambulatory electrocardi...
