Clinical Analysis Of Parts Of Related Problems About Non-neoplastic Hemoptysis Treated By Endovascular Embolotherapy

Objectives:1. To analysis whether combining with tuberculosis or not affects recurrence rates of post-embolization for hemoptysis caused by bronchiectasis.2. To investigate the relationships between pleura changes and the amount of blood-supply vessels in non-neoplastic hemoptysis.3. To analysis the relationships between the embolization's effective ratio, the incidence of side reaction and recurrence rates of post-embolization and causes of non-neoplastic hemoptysis, the pleura changes and the amount of blood-supply vessels, respectively.Methods:From Jan. 1 2004 to Mar. 30 2008, 73 cases of patients with non-neoplastic hemoptysis performed by endovascular embolization were collected. Among of them, 38 cases of bronchiectasis, 7 cases of tuberculosis, 14 cases of vascular malformation, and 14 cases of bronchiectasis combined with tuberculosis.To analysis whether combining with tuberculosis or not affects recurrence rates of post-embolization for hemoptysis caused by bronchiectasis with independent-samples t test.To investigate the relationships between pleura changes and the amount of blood-supply vessels in non-neoplastic hemoptysis with linear correlation analysis.To analysis the relationships between the embolization's effective ratio, the incidence of side reaction and recurrence rates of post-embolization and causes of non-neoplastic hemoptysis, the pleura changes and the amount of blood-supply vessels using multiple factor step wise regression analysis, P<0.05 means significance difference, respectively.Results:1. The mean of recurrence rate of bronchiectasis of post-embolization (10.5%, 4/38) is lower than the mean of recurrence rate of bronchiectasis combining with tuberculosis after embolization(42.8%,6/14) (t= -2211, and P=0.041).2. There is significance linear correlation between pleura's changes and the amount of blood-supply vessels in non-neoplastic hemoptysis.3. Analyses with multiple factor step wise regression analysis show the following:â‘ For bronchiectasis, there is linear correlation between the embolization's effective ratio and the extent of disease, the regression equation is y=-0.155x+3.187;â‘¡For tuberculosis, there is linear correlation between the embolization's effective ratio and the amount of blood-supply vessels, the regression equation is y=-x+4;â‘¢For vascular malformation, there is linear correlation between the incidence of side reaction and pleura change, the regression equation is y=0.69x+0.143.Conclusions:1. The recurrence rate of post-embolization for hemoptysis caused by purified bronchiectasis is much lower than that for bronchiectasis companied by tuberculosis.2. The more pleura adhesion, the more amount of blood-supply vessels.3. For purified bronchiectasis, the broader extent of disease, the lower the effective rate; For companied by tuberculosis, the more serious the pleura adhesion, the more the amount of blood-supply vessels, the lower the effective ratio; For vascular malformation, the more serious the pleura adhesion, the more the side reaction after embolization.
