【摘要】 目的 探讨肝肿瘤热消融过程中四维电磁导航系统在辅助CT引导的应用价值和疗效评估。方法 选择40例需接受单针热消融的单发肝肿瘤患者(肿瘤最大直径≤5 cm),采用随机数字表的方法将40例患者随机分为两组,其中20例患者(导航组)行四维电磁导航系统辅助CT引导下肝肿瘤热消融, 20例患者(对照组)在常规CT引导下行肝肿瘤热消融。记录并比较两组患者热消融过程中的皮肤穿刺次数,针调整次数,穿刺靶目标时间,CT扫描次数,CT透视时间和总剂量乘积(DLP)。观察两组患者热消融术后并发症的情况,并在术后1~2个月随访热消融的效果。结果 导航组20例患者在肝肿瘤热消融的过程中成功应用四维电磁导航系统,导航组与对照组患者的皮肤穿刺次数比为(1.20±0.42)次比(1.25±0.55)次,P=0.803;针调整次数为(2.40±1.17)次比(4.95±3.10)次,P=0.003;穿刺靶目标的时间为(16.50±10.62) min比(15.20±5.82) min,P=0.725;CT扫描次数为(7.10±1.73)次比(10.30±4.09)次,P=0.006;CT透视时间为(40.47±18.71) s比(59.98±32.23) s,P=0.046;CT透视时间和总剂量乘积(DLP)为(807.39±284.79) mGy?cm 比(1 578.67±784.00) mGy?cm,P=0.001。在热消融的过程中40例患者均无严重并发症发生,术后1~2个月随访复查导航组和对照组患者的完全消融率为90.0%和84.2%(P>0.05)。结论 四维电磁导航系统辅助CT引导下肝肿瘤热消融可明显减少热消融过程中消融针调整次数,CT扫描次数和CT透视时间,同时可大大降低患者接受的辐射剂量。但仍需要进一步的研究来确定四维电磁导航系统的应用效果。
