【摘要】：目的评价智能导引装置(ROBIO)辅助CT引导下肺穿刺活检术的可行性和安全性。方法对20例患者行ROBIO辅助CT引导下肺穿刺活检术,记录操作时间、定位时间、穿刺次数、扫描次数、辐射剂量、瞄准精度以及并发症情况。结果肺活检平均操作时间为(32±8.3)min(24~50min),平均定位时间为(13.8±4.1)min(8~27min)。20例患者成功19例,共穿刺了20次,平均穿刺次数为(1.1±0.2)次(1~2次)。平均扫描次数为(3.6±0.8)次(3~6次),剂量长度乘积(DLP)均值为(570.5±167.8)m Gy·cm(411.5~1117.5 m Gy·cm)。20次穿刺定位中,16次瞄准精度5 mm,3次为5~10 mm,1次为12 mm,穿刺针瞄准精度均值为(3.7±2.2)mm(1~12mm)。20例中气胸2例,血胸1例,无严重并发症发生。结论 ROBIO辅助CT引导下肺穿刺活检术定位时间短,穿刺精确度高,并发症发生率低,是一种导引肺穿刺定位安全、有效的方法。
[Abstract]:Objective to evaluate the feasibility and safety of CT guided lung biopsy with intelligent guidance device (ROBIO).Methods ROBIO assisted CT guided lung biopsy was performed in 20 patients. The operation time, location time, puncture times, scanning times, radiation dose, aiming accuracy and complications were recorded.Results the average operation time of lung biopsy was 32 卤8.3 minutes, 24 minutes and 50 minutes respectively, and the mean localization time was 13.8 卤4.1)min(8~27min).20 in 19 cases. The total number of puncture was 20 times and the average number of punctures was 1.1 卤0.2 times (1. 1 卤0. 2) times.The average scanning times were 3. 6 卤0. 8 times, and the average dose length product was 57. 5 卤167. 8 mGy cm(411.5~1117.5 / mGy cm).20 times. The aim accuracy of 16 times was 5 mm and 3 times was 510 mm and 12 mm, the mean aiming accuracy of puncture needle was 3. 7 卤2.2)mm(1~12mm).20 in 2 cases, and that of hemothorax in 1 case, there were 2 cases of pneumothorax and 1 case of hemothorax in the average scanning frequency of 3. 6 卤0. 8 times, 2 cases of pneumothorax, 1 case of hemothorax, and 1 case of hemothorax.No serious complications occurred.Conclusion ROBIO assisted CT guided lung biopsy is a safe and effective method for guiding lung puncture location with short localization time, high accuracy and low incidence of complications.
