Bronchial arteriography and embolotherapy were performed to control hemoptysis in 11 patients with advanced stages of cystic fibrosis. Two patients suffered massive, 1 moderate, and 8 mild but recurrent hemoptysis. The embolization procedures were performed with Gelfoam, Ivalon, and coils in one to four separate procedures. Altogether, 19 of 20 procedures were successful, with follow-up periods ranging from 9 months to 8 years. No serious complications were encountered except for one femoral artery pseudoaneurysm which required surgical repair. Rapid digital subtraction angiography and "roadmapping" were considered helpful in avoiding the complication of reflux embolization and expediting the procedures. Bronchial embolization is a life-saving procedure for severe hemoptysis in patients with cystic fibrosis and is considered safe enough to include the indications of moderate and mild/recurrent hemoptysis to improve the quality of life in these patients.
