【摘要】：[目的]评估同心球定位导向技术对椎间孔镜辐射剂量及其相关疾病风险的影响。[方法]回顾性分析2015年10月~2016年8月共127例行经皮椎间孔镜椎间盘切除患者的资料。其中,64例采用同心球定位导向技术进行辅助穿刺的病例被视为导向组,63例采用常规手动盲穿的患者被视为常规组。观察比较穿刺次数、C型臂X线机透视次数及总曝光时间、手术时间和估算的辐射剂量及相关疾病的风险。[结果]平均穿刺次数导向组为(1.59±0.66)次,常规组为(4.83±1.76)次;总透视次数导向组为(27.38±5.11)次,常规组为(36.97±7.52)次;总曝光时间导向组为(26.27±4.75)秒,常规组为(33.51±7.08)秒;辐射有效剂量导向组为(0.49±0.09)mSv,常规组为(0.63±0.14)mSv;癌症风险导向组为(26.75±4.89)×10~(-9),常规组为(34.39±7.50)×10~(-9);遗传疾病风险导向组为(0.97±0.18)×10~(-9),常规组为(1.25±0.27)×10~(-9);导向组手术时间(62.91±10.03)min,常规组(69.84±10.49)min;以上指标两组间比较差异均具有统计学意义(P0.001)。两组患者的满意度和并发症的差异皆无统计学意义(P0.05)。[结论]同心球定位导向技术可以明显提高椎间孔镜穿刺的准确性,减少手术时间,降低患者辐射有效剂量,进而降低患者罹辐射相关病症、遗传疾病的风险。
[Abstract]:Objective: to evaluate the effect of concentric ball orientation on the radiation dose of intervertebral foramen and its associated disease risk.[methods] the data of 127 patients with percutaneous foramen discectomy from October 2015 to August 2016 were retrospectively analyzed.Among them, 64 patients who were guided by concentric ball orientation technique were regarded as guidance group and 63 patients with routine manual blind puncture were regarded as routine group.The fluoroscopy times, total exposure time, operation time, estimated radiation dose and the risk of related diseases were observed and compared.[results] the average puncture times were 1.59 卤0.66 times in the guidance group, 4.83 卤1.76 times in the routine group, 27.38 卤5.11 times in the total fluoroscopy group, 36.97 卤7.52 times in the routine group, 26.27 卤4.75 seconds in the total exposure time guide group and 33.51 卤7.08 seconds in the routine group.It has statistical significance (P 0.001).There was no significant difference in satisfaction and complication between the two groups (P 0.05).[conclusion] the concentric ball positioning and guiding technique can significantly improve the accuracy of intervertebral foramen puncture, reduce the operative time, reduce the effective dose of radiation, and then reduce the risk of radiation-related diseases and genetic diseases.
