[Therapeutic embolization of pulmonary arteriovenous malformations]

It is reported on the practicability and the results of therapeutic embolizations in 7 patients with pulmonary av-malformations. The embolizations were carried out by detachable balloons. In all cases there were immediate and well-defined occlusions. In direct fistulas the embolization represents a curative procedure. However, in cases of angiomatous malformations with slow flow character, only a reduction of shunt or decreasing of size is obtained.
