OBJECTIVE: To investigate the long-term effect of bronchial arterial embolization with different material and procedure on patients with hemoptysis.

METHOD: Seventy two cases were divided into two groups, one received the double embolization of bronchial artery, the other group used single gelfoam embolization. In double embolization group, the mixture containing gelfoam microspheres (0.5 mm x 0.5 mm), erythromycin and high osmalality sodium chloride were firstly used to embolize the terminal vessels, the gelfoam particle (1 mm x 1 mm) was then used to embolize the main trunk of bronchial artery.

RESULT: After 2-4.8 years following up, it turned out that the cure rate and general effectiveness were: the double embolization group 83%, 100% respectively, the single gelfoam embolization group 61%, 95%. By comparison, there were significant difference on cure rate between these two groups(P < 0.05).

CONCLUSION: The bronchial arterial double embolization will increase the long-term effect obviously on patients with hemoptysis.
