支气管动脉CTA对介入栓塞治疗咯血的指导及应用价值

目的探讨支气管动脉CT血管成像（CTA）对咯血介入治疗的指导作用及效果。 方法将34例咯血患者按介入栓塞治疗前是否行支气管动脉CTA检查分为单纯DSA组及术前CTA组，每组17例。比较两组检出可疑出血动脉情况、手术时间及术后一年复发率，分析术前CTA组的CTA血管检出率。 结果术前CTA组共检出可疑出血动脉28支，单纯DSA组检出31支，并全部予以栓塞。术前CTA组的手术时间为（28.33±7.68）min，低于单纯DSA组的（40.55±10.01）min，差异有统计学意义（t=4.03，P<0.05）。 结论支气管动脉CTA可以客观评价咯血相关血管的起源、数目及走形，可为术中寻找出血动脉提供准确的定位。并且能减少手术时间及医患人员的辐射剂量，避免漏栓，降低复发几率，对指导咯血的介入治疗有重要的临床应用价值。

Clinical value of bronchial artery CTA on interventional embolization in the treatment of hemoptysis

ObjectiveTo evaluate the role of bronchial artery CTA on interventional embolization in the treatment of hemoptysis. Methods34 cases treated with interventional embolization for hemoptysis was included in the study. They were divided into two groups according to whether bronchial artery CTA was performed. Group A (n=17) is those who performed DSA directly without preoperative CTA, while group B (n=17) is those with preoperative CTA peformed.The results of CTA and DSA, technical and clinical outcomes were compared and analyzed. Results28 hemorrhage arteries were identified in group B while 31 in group A. All these identified arteries were embolized successfully. The ray time of group B is shorter than group A ( min:28.33±7.68 vs. 40.55±10.01, t=4.03, P <0.05). ConclusionsBronchial artery CTA can objectively evaluate hemoptysis associated vascular origin, number and shape, but the bleeding artery to provide accurate positioning for intraoperative finding. And can reduce the radiation dose of operation time and the doctors and patients, to avoid leakage bolt reduce the recurrent rate of hemoptysis interventional therapy guidance has wide clinical application value.
