【摘要】 目的:探討CT精確引導(dǎo)三維立體全身穿刺定位裝置在臨床腫瘤穿刺操作中的應(yīng)用。方法:將CT診斷為占位病變并需要CT引導(dǎo)下進(jìn)行穿刺明確診斷或者局部治療的患者100例按隨機數(shù)字表法分為觀察組和對照組,每組各50例,觀察組采用CT精確引導(dǎo)三維立體全身穿刺定位裝置引導(dǎo)穿刺,對照組采用傳統(tǒng)的CT引導(dǎo)下徒手穿刺。結(jié)果:觀察組一次性穿刺成功率為94%,對照組為52%;觀察組出血發(fā)生率2%,對照組14%;觀察組未發(fā)生感染,對照組感染率12%;觀察組氣胸發(fā)生率4%,對照組氣胸發(fā)生率32%;兩組比較,差異均有統(tǒng)計學(xué)意義(P<0.05)。結(jié)論:CT精確引導(dǎo)三維立體全身穿刺定位裝置設(shè)計先進(jìn),操作簡單,三維立體適應(yīng)范圍廣,全身應(yīng)用,一次穿刺成功率高,從而降低了并發(fā)癥發(fā)生率,適合基層醫(yī)院使用,值得推廣。

【Abstract】 Objective: To evaluate the clinical application of puncture positioning frame guided by three-dimensional CT in tumor puncture. Method: 100 patients with placeholder disease diagnosed by CT, who need to make a definite diagnosis by puncture guided by CT or local treatment, randomly divided into two groups. The observation group used puncture positioning frame guided by three-dimensional CT, the control group chose traditional puncture method guided by CT. Result: The success rate of puncture by one-time of the observation group was 94%, and that of the control group was 52%. The incidence of bleeding of the observation group was 2%, and that of the control group was 14%. The infection rates of the control group was 12%, and there was no infection in the observation group. The incidence of pneumothorax was 4% in the observation group, but the control group was 32%. The difference was statistically significance between the two groups. Conclusion: The puncture positioning frame designs is of novel, high precision, high success rate and shorter puncture time. It has low complication and is worth promoting in clinical.

CT具有分辨率高等優(yōu)勢,已被廣泛應(yīng)用于全身各部位穿刺活檢或介入性治療時的導(dǎo)向[1]。目前在CT定位引導(dǎo)下經(jīng)皮腫瘤靶點穿刺活檢及微創(chuàng)治療已廣泛開展,但多為徒手穿刺法,該技術(shù)受個人技術(shù)等因素限制,穿刺角度較難準(zhǔn)確把握,穿刺針穩(wěn)定性差,誤差大,一次操作成功率低[2-3]。高端激光定位引導(dǎo)技術(shù)(pinpiont技術(shù))Pinpoint系統(tǒng)應(yīng)用于CT引導(dǎo)下的穿刺活檢或治療[4],定位精確、操作穩(wěn)定,是CT介入治療的一大進(jìn)步[5]。雖然穿刺準(zhǔn)確率高,但因價格昂貴難以普及。為此本科室自行研制CT精確引導(dǎo)三維立體全身穿刺定位裝置。臨床應(yīng)用50例,并與傳統(tǒng)的CT引導(dǎo)下徒手穿刺50例對比,現(xiàn)報告如下。
1 資料與方法
1.1 一般資料 將本院2009年2月-2011年3月CT診斷為占位病變并需要CT引導(dǎo)下進(jìn)行穿刺明確診斷或者局部治療的患者100例按隨機數(shù)字表法分為觀察組和對照組。其中男55例,女45例,年齡25~78歲,中位年齡(58±3.2)歲;肺部腫瘤50例,肝內(nèi)腫瘤及肝轉(zhuǎn)移瘤38例,盆腔及后腹膜腫瘤8例,腎上腺腫瘤2例,椎旁腫瘤2例;腫瘤體積最小2.5 cm×2.0 cm×1.4 cm,最大12.0 cm×9.0 cm×8.5 cm。兩組患者一般資料比較,差異無統(tǒng)計學(xué)意義(P>0.05),具有可比性見表1。
1.2 儀器 本實驗使用一種三維立體CT全身精確引導(dǎo)穿刺定位裝置,包括支撐架、水平定位架、豎向定位架、指針和穿刺引導(dǎo)套管。水平定位架呈圓弧形,在水平定位架圓弧頂點的外側(cè)設(shè)置有萬向球頭,在水平定位架的圓弧形內(nèi)側(cè)中部固定連接有連接桿,連接桿的另一端設(shè)置有穿刺引導(dǎo)套管和豎向定位架。所述的穿刺引導(dǎo)套管下端與橫板的前端鉸接連接,其上端設(shè)置有可拆卸連接的指針,穿刺引導(dǎo)套管與連接板的連接處設(shè)置有緊固螺釘。見圖1。endprint
