【摘要】：目的探討微輻射技術(shù)在導航引導經(jīng)皮椎體成形術(shù)(PVP)中減少輻射的效果。方法通過3項手術(shù)器械(體表椎體定位器、經(jīng)皮導航動態(tài)參考架、導航專用穿刺針)的研制和2項引進技術(shù)(雙鉛板和骨水泥液壓輸送)的應用,與現(xiàn)有導航引導下PVP進行對比。因單椎體骨折行PVP患者80例,隨機分為改良組和對照組各40例,改良組使用通過3項手術(shù)器械研制和2項引進技術(shù)的應用得以改良的微輻射技術(shù),對照組使用目前國內(nèi)醫(yī)院常用的導航引導下PVP,術(shù)后隨訪12個月,觀察分析手術(shù)前后VAS評分、平均手術(shù)時間和術(shù)者暴露劑量。結(jié)果 80例椎體成功注射骨水泥,無嚴重并發(fā)癥,術(shù)后隨訪時間8~24個月,平均16個月,所有患者手術(shù)前后VAS評分均有顯著差異,兩組間差異不明顯。改良組平均手術(shù)時間少于對照組,術(shù)者暴露劑量明顯低于對照組(P0.01)。結(jié)論采用微輻射技術(shù)的導航引導下PVP,能有效縮短手術(shù)時間,特別是能明顯減少術(shù)者暴露劑量,大大提高了需反復承受醫(yī)療輻射術(shù)者的人身安全。
[Abstract]:Objective to evaluate the effect of microradiation in navigation guided percutaneous vertebroplasty (PVP). Methods through the development of three kinds of surgical instruments (body surface vertebrae positioner, percutaneous navigation dynamic reference frame, navigation special puncture needle) and the application of two imported techniques (double lead plate and bone cement hydraulic transportation). Compared with PVP under existing navigation guidance. Eighty patients with PVP due to single vertebral body fracture were randomly divided into two groups: the modified group (n = 40) and the control group (n = 40). Patients in control group were followed up for 12 months under the guidance of navigation, and VAS scores, mean operating time and exposure dose were observed and analyzed before and after operation. Results 80 cases of vertebral body were injected with bone cement successfully without serious complications. The follow-up time was 8 ~ 24 months (mean 16 months). There was significant difference in VAS score between the two groups before and after operation, and there was no significant difference between the two groups. The average operation time of the modified group was less than that of the control group, and the exposure dose of the operation group was significantly lower than that of the control group (P0.01). Conclusion under the guidance of microradiation, PVP can effectively shorten the operation time, especially reduce the exposure dose of the operator, and greatly improve the safety of the patients who need repeated medical radiation.
