目的　探讨肺动静脉瘘的影像学表现及介入治疗方法和疗效。方法　 9例低氧血症患者经影像学明确诊断为肺动静脉瘘 ,将导管超选择至肺动静脉瘘口处 ,间断释放COOK公司生产的直径 0 .5～ 1.0cm的弹簧栓子 [MWCE 38-5 -5 -1.2 ]。经DSA证实 ,瘘口闭塞 ,病变区不再显影。结果　 9例患者 8例栓塞成功 ,其中 2例经 2次栓塞治疗。术后血氧饱和度平均升高 14 %。释放弹簧栓子数最多 44枚 ,最少 12枚。经 2年随访 ,血氧饱和度稳定在 90 %～ 97%。结论　对肺动静脉瘘患者栓塞治疗操作简单、安全、疗效可靠 ,是该病的首选治疗方法。 Objective To investigate the imaging manifestations of pulmonary arteriovenous fistula and its interventional therapy and efficacy. Methods Nine patients with hypoxemia were diagnosed as pulmonary arteriovenous fistula by imaging, the catheter was surgically selected to the pulmonary arteriovenous fistula, intermittent release of 0.5 ~ 1.0cm diameter spring emboli [MWCE 38-5 -5 -1.2]. DSA confirmed that the fistula occlusion, lesions no longer develop. Results Eight of the nine patients were successful in embolization, of which two were treated with two embolizations. Postoperative oxygen saturation increased by an average of 14%. Release the number of spring embossments up to 44, at least 12. After 2 years of follow-up, blood oxygen saturation stabilized at 90% to 97%. Conclusion The embolization of pulmonary arteriovenous fistula patients is simple, safe and reliable, which is the first choice of treatment.
