【摘要】：目的探讨支气管动脉CTA对支气管动脉栓塞术(BAE)的指导作用。方法回顾性分析48例先后接受支气管动脉CTA及BAE的咯血病例,利用CTA MPR、VR及MIP技术准确、清晰记录支气管动脉分布情况、起源位置及方位、形态改变及非支气管动脉供血情况,并与BAE术中造影结果进行对比。结果 46例咯血患者(除外2例肺栓塞患者)CTA共检出102支支气管动脉,其中57支起源于T5~6椎体水平降主动脉,左侧支气管动脉供血6例,右侧支气管动脉供血9例,双侧支气管动脉共同供血31例;支气管动脉造影(BAG)检出的支气管动脉分布为左侧支气管动脉供血8例,右侧支气管动脉供血13例,双侧支气管动脉共同供血25例,两种方法检出的支气管动脉分布类型差异无统计学意义(P0.05)。CTA检出起源于降主动脉其他水平及其他体循环动脉(异常起源)45支,BAG检出2支。支气管动脉CTA检出20支支气管肋间动脉干,BAG检出4支。CTA检出11例非支气管动脉供血,BAG检出8例。在显示支气管肋间动脉干、非支气管动脉尤其是异常起源的支气管动脉方面,CTA优于BAG。结论支气管动脉CTA准确率高,可以为BAE提供详细的解剖信息,优化治疗方案,提高栓塞的准确率及效率,降低漏栓率。
[Abstract]:Objective to investigate the guiding effect of bronchial artery CTA on bronchial artery embolization. Methods 48 patients with hemoptysis received bronchial artery CTA and BAE were analyzed retrospectively. The distribution, location and location of bronchial artery, morphological changes and blood supply of non-bronchial artery were recorded clearly. Results A total of 102 bronchial arteries were detected in 46 patients with hemoptysis (except 2 patients with pulmonary embolism). There were 9 cases of right bronchial artery supply, 31 cases of bilateral bronchial artery supply, 8 cases of left bronchial artery supply and 13 cases of right bronchial artery supply. 25 cases of bilateral bronchial artery blood supply, There was no significant difference in the distribution types of bronchial arteries detected by the two methods. The detection of bronchial arteries originated from other levels of descending aorta and other systemic circulation arteries (abnormal origin was detected in 45 branches of BAG and 20 branches in CTA of bronchial arteries). Four branches of trachea intercostal artery trunk were detected by BAG. CTA was used to detect 11 cases of non-bronchial artery supplying blood and 8 cases were detected. Conclusion CTA of bronchial artery is superior to BAG.Conclusion CTA of bronchial artery can provide detailed anatomical information for BAE, optimize treatment plan, improve the accuracy and efficiency of embolization, and reduce the rate of thrombus leakage.
