The Effective Factors Of Interventional Therapy In Hemoptysis

Objective To evaluation the interventional therapy in hemoptysis of different blood supply, the effect of embolization method and recurrent factors. Mehtods 120 patients of hemoptysis with bronchial arteries and close region of angiography, and embolized bleeding artery with super-selective incubation. The blood supply of patients will be divided into simple arteries feeding and multi-branch artery two groups.Based on the agents of embolization,all the patients will be divided into gelfoam group, PVA group, PVA and gelfoam . It is two groups ,recuring group and not not relapsed group according to the therapeutic effect.All the data are used to set up Logistic and Cox modle. Result 120 cases of patients with embolization were completed cessation of hemoptysis, and technical successful rate was 100%. Followed-up 1-7 years, 35 patients relapsed, the overall effective rate was 70.83%.The embolization with Gelfoam only is in the most possibility of recurrent.There is no distinctive disparity between Gelfoam group and PVA group. Diseased region with multi blood supply is 13.3 times to recurrence than solo blood supply after embolization.The therapy with only Gelfoam is most likely to relapse and has shorter time to recur. Conclusion The embolization with PVA or Gelfoam and PVA is a effective procedure for hemoptysis .The embolic agent with Gelfoam only and the patients with multi blood supply to dieased region dose not have a satisfactory outcome.
