同轴凝血退针法在CT引导下经皮肺穿刺活检中的应用

目的探讨同轴凝血退针法在预防CT引导下经皮肺穿刺活检并发症中的价值及其优缺点。方法将134例进行CT引导下经皮肺穿刺活检患者分成两组:61例CT引导下经皮肺穿刺活检患者采用常规方法进行穿刺活检为对照组,73例CT引导下经皮肺穿刺活检患者采用同轴凝血退针法进行穿刺活检为研究组。统计并比较两组的术后并发症。结果CT引导下经皮肺穿刺活检术中,对照组气胸20例,发生率为32.7%,研究组8例(10.9%),两者差异具有统计学意义(P<0.05);对照组15例出血,发生率为24.5%,研究组7例出血,发生率为9.6%,两组差异具有统计学意义(P<0.05),同轴凝血退针法穿刺并发气胸和出血的概率均低于传统方法。结论同轴凝血退针法在CT引导下经皮肺穿刺活检应用中优于传统方法,并发症低,具有应用前景,值得推广普及。

Application of coaxial thrombin needle withdrawal technique in CT-guided percutaneous lung biopsy

Objective To evaluate coaxial thrombin needle withdrawal technique in preventing complications of CT-guided percutaneous lung biopsy,and to discuss its advantages and disadvantages.Methods A total of 134 patients receiving CT-guided percutaneous lung biopsy were enrolled in this study.The patients were divided into study group(n=73)and control group(n=61).For the patients of the control group,CT-guided percutaneous lung biopsy was performed by using conventional puncture technique,while for the patients of the study group,CT-guided percutaneous lung biopsy was carried out by using coaxial thrombin needle withdrawal technique.The postoperative complications of both groups were recorded and compared.Results The incidences of pneumothorax in the study group and in the control group were 10.9%and 32.7%respectively,the difference between the two groups was statistically significant(P<0.05).The incidences of bleeding in the study group and in the control group were 9.6%and 24.5%respectively,the difference between the two groups was statistically significant(P<0.05).The incidences of both pneumothorax and bleeding in the study group were remarkably lower than those in the control group.Conclusion In performing CT-guided percutaneous lung biopsy,the coaxial thrombin needle withdrawal technique is superior to the conventional puncture technique in lowering the incidence of complications.Therefore,this technique has clinical application prospect and it is worth popularizing in clinical practice.
