CT引导下用同轴技术对肌肉骨骼肿瘤26例行穿刺活检的体会

The Clinical Understanding on 26 Cases of CT-guided Muscleorskeleton Tumor Puncture Biopsy with the Co-axle Technique

目的:评价应用同轴活检技术,进行CT引导下肌肉骨骼肿瘤穿刺活检的临床应用价值。方法:CT引导下同轴技术穿刺活检肌肉骨骼肿瘤26例,同轴套管针于穿刺点按预定角度、深度快速穿刺,针尖至肿瘤边缘内或近穿刺点1/ 3处,经同轴套管针置入自动活检针,适度改变同轴套管针方向,不同角度、深度对肿瘤进行切割,取材,固定后行病理学检查。结果:26例患者穿刺成功率100%,病理检查明确诊断率92.3%(24/26),无1例严重并发症。结论:CT引导下同轴技术肌肉骨骼肿瘤穿刺活检,可多次、多点取材,提高阳性率以及正确诊断率,降低并发症发生率,此项技术简便易行,是一种安全、有效的诊断措施。

Objective： To evaluate the clinical application value of CT-guided muscleorskeleton tumor puncture biopsy with the co-axle transfixion pin biopsy technique. Methods： The clinical data of 26 cases of CT-guided muscleorskeleton tumor puncture biopsy with the co-axle transfixion pin biopsy technique. Under the prepared angle and depth puncture quickly in the puncture point using the co-axle casing needle. When the needle reached the edge of tumor or the near 1/3 the puncture point. Implant the automatic biopsy needle through the co-axle casing needle. Moderate change the direction of the co-axle casing needle and making different angle and depth dissection and fast cytological examinationg of the sampple. Rusullts ： The success rate of the puncture about the 26 cases were 100% . The accuracy and false negative rate of the puncture biopsy were 92. 3% （24/ 26） . The produced rate of the compplication after puncture were 0% （0/26）. Conclusion： CT-guided muscleorskeleton tumor puncture biopsy with the co-axle technique, can selected many times and points. Improved the positive rate and the accuray rate, reduced the produced rate of the complication. It is a easy technique. It is a safer and efficacious diagnose measure.
