影像融合导航技术与CT在引导经皮肺穿刺活检中的应用价值比较

目的比较超声-CT影像融合导航技术引导下与CT引导下经皮肺穿刺活检对肺部周围型病变诊断的临床应用价值。 方法回顾性分析2015年11月至2016年10月在佛山市第一人民医院经胸部CT确诊为肺部周围型病变需行经皮肺穿刺活检术，明确诊断的患者64例，其中经影像融合导航技术引导组32例，经CT引导组32例，采用四格表χ²检验比较两组穿刺成功率和并发症发生率差异。 结果影像融合引导组穿刺成功率93.8%（30/32），CT引导组穿刺成功率100.0%（32/32），两组比较，差异无统计学意义（χ²=0.52，P=0.47）。影像融合引导组气胸、咯血等并发症发生率6.3%（2/32），CT引导组并发症发生率25.0%（8/32），两组比较，差异有统计学意义（χ²=4.27，P=0.04）。 结论经影像融合导航技术引导下经皮肺穿刺活检成功率较高、并发症发生率较低，是引导超声不能显示的肺部周围型病变穿刺活检的重要手段。

Clinical value of image fusion navigation and CT in guiding percutaneous lung biopsy

ObjectiveTo investigate the clinical value of image fusion navigation and CT in percutaneous lung biopsy for peripheral lung lesions. MethodsSixty-four peripheral lung lesions were included in the research.These patients were divided into image fusion-guided group (32 cases) and CT-guided group (32 cases).The accuracy of puncture and the incidences of complications were comparatively analyzed. ResultsThirty cases (93.8%) were successfully punctured in the image fusion-guided group,and 32 cases (100%) were successfully punctured in CT-guided group,there was no significance difference between the two groups (P=0.47). The incidences of complications was 6.3% (2/32) in image fusion-guided group and 25.0%(8/32) in CT-guided group, there was a significantly difference between the two groups (P=0.04). ConclusionImage fusion-guided percutaneously transthoracic lung biopsy is a safe and accurate diagnostic procedure for peripheral lung lesions.
