支气管动脉畸形的DSA表现及栓塞治疗

目的 探讨支气管动脉畸形大咯血的ＤＳＡ表现，观察栓塞治疗的疗效。方法 采用Ｓｅｌｄｉｎｇｅｒ技术行股动脉穿刺插管，将Ｃ３导管选择性插入支气管动脉，高压注入３８％泛影葡胺，第次总量６￣８ｍｌ，０．５￣１．０ｍｌ／ｓ，行正位ＤＳＡ，分析支气管动脉畸形的ＤＳＡ表现，确诊后用对比剂稀释的明胶海绵粉进行栓塞，随访栓塞疗效。结果 ⑴ＤＳＡ表现：６例患者两侧或单侧支气管动脉主干或（和）分支示增粗、扩张、扭曲、粗

Objective To study the manifestations of DSAof bronchial artery andthe clinical effectof embolization- Methods Transfemoral Seldingertechnique was used in all 6 cases using a cobra C3 catheter selectivelyinto bronchialartery- Theamountofcontrast medium injectedrangedfrom 5to8 mlperinjection,ata rateof0-5-1-0 ml/s- Gelfoam powder was used for embolization- Results Theright and(or) left bronchial artery and(or)itsbranchesshowed enlargement,twisting,irregulardiameter,and extravsation ofcontrast medium wasobserved because of bleeding- One case had a left bronchial artery malformation with a artery artery artery venousfistula- 5/6 patients weretreated with BAE,bleeding stopped after BAE- Bleedingrecurredin onepatient after2 month,DSAshow partialrecanalization ofbronchialartery- Afterthesecondembolization,the bleeding was controlled-5/6 patients werefollowed for 6 years,5 years,3 years,2 years,and 6 months respectively,without recurrenceofhemoptysis,theclinicaleffectwasgood- Conclusions DSAisthe methodofchoiceto diagnosisthe malformation ofbronchialartery -Theclinicaleffectof BAEwith gelfoam powderis good withlesscomplications-
