Bronchial arteries embolization is a routine treatment of hemophtysis. In patients affected by cystic fibrosis hemophtysis is often very serious, dangerous for their life. The extent of pulmonary lesions, the frequent bilaterality and respiratory dysfunction are contraindications to operation. The authors report their experience on three patients affected by cystic fibrosis with hemophtysis, in which bronchial embolization has been the only therapeutic choice. It performed a good result with immediate stopping of hemophtysis. In all three cases results were not serious relapses, but only rare slight hemophtysis.
