[Chiari network and pulmonary embolism].

We present the case of a patient with acute pulmonary embolism, Chiari network thrombus, and deep vein thrombosis in lower extremities. Chiari networks are present in the right atrium in a minority of population and are usually of no clinical significance. On the other hand it may be associated with such pathological changes as patent foramen ovale, intraatrial thrombus, or atrial arrhythmias. In our case thrombus was trapped by a Chiari's network.
