经皮冷冻治疗644例肺癌的常见并发症分析及处理

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 cardivascular 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.
