Abstract
The occurrence, in one patient, of a life-threatening pulmonary embolus 3 days following
insertion of a Mobin-Uddin umbrella filter promoted a review of our experience with
this device. Over the past 5 years, 41 patients had umbrella filters inserted at the
Beth Israel Hospital. Five patients (12%) had proven or probable pulmonary embolization
following filter placement. In four of the seven autopsied patients, thrombus was
found on the cardiac side of the umbrella, and in one of these patients a fresh embolus
was also found in the pulmonary artery. We conclude that the standard (nonheparin-impregnated)
Mobin-Uddin umbrella device offers incomplete protection against pulmonary embolization
in patients who cannot concurrently receive anticoagulant drugs.
