Coil embolization in the treatment of pulmonary arteriovenous malformations.

Twenty-eight pulmonary arteriovenous malformations in six patients were treated with coil embolization. The technique of embolization and the precautions taken to avoid complications are described. All patients had good relief of their symptoms and an improvement in arterial oxygenation. The observed complications were minor and our technique has now been modified to avoid these.
