The interventional treatment of intractable epistaxis

Objective:To evaluate selective angiographic diagnosis and superselective embolization of intractable epistaxis in 21 cases.Methods:The seldinger technique was used in all patients. The catheter was introduced via femoral artery on the right side. Selective angiographic analysis and diagnosis were performed.Superselective angiographic embolization with silk thread in diamend form 140 to 250 um was performed in bleeding vessels.Results:All cases achieved satisfactory effect. During the follow-up 2 to 12 month, no patients recurrence nose bleeding. 8 cases were operated in 1 week. Bleeding reduced sharply in operation,and operative difficulty cut down and operative success rate was increased. Conclusion:Selective angiographic diagnosis,and Superselective angiographic embolization,and suitive size of silk thread granular,and appropriate embolic speed are critical for successful treatment of massive epistais,Maxillary artery embolization is safe,effective,and uncomplicated Interventional embolization has afforded a new methed for acoustic-nasola-larynxologic operation.
