不同栓塞剂对介入治疗咯血短期疗效的影响

Different embolic agents' influences on the short-term curative effect of treatment for hemoptysis by interventional therapy

目的探讨不同栓塞剂对支气管动脉栓塞治疗咯血短期疗效的影响。方法咯血患者46例,进行支气管动脉栓塞治疗咯血。栓塞前进行造影,根据病灶是否有难以栓塞的非支气管体循环动脉供血进行配对分组,分别以明胶海绵颗粒或PVA颗粒栓塞。结果明胶海绵栓塞组的有效率为78.3%,PVA颗粒组有效率为82.6%。两组有效率无明显差别。所有疗效不佳的病例都发生在非支气管体循环供血动脉不能充分栓塞者。结论充分栓塞支气管和非支气管体循环动脉是介入治疗咯血成功的关键;选择何种栓塞剂对短期疗效无显著影响。

Objective To explore the different embo｜ic agents＇ influences on short-term curative effect in treating hemoptysis by bronchial artery embolization. Methods The subjects were 46 cases of hemoptysis and they were treated by bronchial artery embolization. Before the embolization, angiography was conducted. They were grouped based on whether there existed some lesions that were difficult to embolize because of non-bronchial systemic artery, and then they were embolized by PVA particles and gelatin sponge particles respectively. Results The group of gelatin sponge embolization had the effective rate of 78.3% ,while PVA particles 82. 6%. In statistical tests, the two groups had no significant difference in efficiency. The poor efficacy of all cases occurred in the non-bronchial systemic artery embolization that was not fully conducted. Conclusion The key to the successful treatment for hemoptysis by the interventional therapy is the full embolization of bronchial and non-bran chial systemic artery. It has no significant influence on short-term effect to choose different embolic agents.
