Abstract:
Objective To investigate the risk factors and correlation of rebleeding after bronchial artery embolization (BAE) in patients with hemoptysis.
Methods Seventy-five patients with hemoptysis who were treated with BAE were divided into two groups based on with or without rebleeding after BAE. Comparison and correlation on the influence of different factors such as age, gender, protopathy, pathogenesis, amount of bleeding, emboliaztion agents, angiography and so on were analyzed in detail.
Results Rebleeding after BAE were diagnosed in 17.33% (13/75) cases. During all the factors, only the bronchial-pulmonary artery/vein shunt between the two groups showed significant difference. Other factors such as age, gender, protopathy, pathogenesis, amount of bleeding, emboliaztion agents have no difference. Multivariate regression analysis justified esophageal fistula was strongly related to post operative hemorrhage.
Conclusions Bronchial-pulmonary artery/vein shunt is the main risk factor of rebleeding after BAE.
