Abstract：Objective To explore the digital subtraction angiography (DSA) features and interventional embolization strategy of patients with cryptogenic hemoptyisis.Methods We retrospectively analyzed the DSA manifestations in patients with cryptogenetic hemoprysis,who were admitled to our liospital from January 2013 to December 2015 for interventional embolization stratrgy.The hemostatic and curative effects were observed after the operation.Results The main DSA showed the tortuous,thickening,disorders of responsible arteries,contrast agent spill,etc among the 36 patients.According to the DSA,the suitable interventional embolization method was chosen.Hemoptysis was stopped immediately after interventional embolization in all patients,and they were followed up for 11 months to 36 months.There were 5 cases (13.89％) with hemoptysis recurrence.The difference of simple gelatin sponge embolization,simple embolization microspheres embolization,embolization microspheres,gelatin sponge or coil mixed embolization was statistically significant in curative effect.Methods 2 and 3 were superior to method 1.Conclusion For patients with cryptogenic hemoptysis,the main DSA manifestations was bronchial artery abnormalities.The use of permanent embolization agent interventional embolization treatment,the recurrence rate is low,and the effect is significant.
