BACKGROUND AND OBJECTIVE: Most lung cancer patients present an advanced stage at diagnosis without suitable surgical chances. Cryotherapy has been applied to the advanced lung cancer with safety and effectiveness. The aim of this study is to analyze the most common complications that occur after percutaneous cryoablation when applied to advanced lung cancer METHODS: Total 644 lung cancer patients had been treated with percutaneous cryoablation guided by ultrasound and/or CT scan. The cardiovascular and respiratory complications were monitored. RESULTS: Complications were relatively minor and could be controlled with routine methods. Serious complications included cardiac arrest and hemopneumothorax, and thus preventative steps should be taken. CONCLUSION: Percutaneous cryoablation for lung cancer is a simple, effective and relatively safe method, but attention should be paid to the possible complications during cryoablation.

心血管系统并发症The major complications of cardiovascular system呼吸系统的并发症主要有:①哮喘发作,9例,占本组病例的1.4%,使用糖皮质激素、氨茶碱等药物解痉平喘,重者用呼吸机辅助呼吸等对症处理;②咯血,357例,其中大咯血4例,分别占本组病例的55.4%和0.6%,可使用止血剂对症处理;③血气胸,209例,占本组病例的32.5%,可采用胸穿、闭式引流等方法对症处理;④肺部感染,43例,其中4例发展为呼吸衰竭,分别占本组病例的6.7%和0.6%,可使用抗生素对症处理,重症呼吸衰竭患者可行气管切开、呼吸机辅助呼吸;⑤发热,105例,占本组病例的16.3%,使用药物对症处理。以上呼吸系统并发症的病例,经对症处理、积极抢救后,血气胸死亡1例,呼吸衰竭死亡2例。本组所有病例并发症相关总死亡率为0.47%(表 2)。
