摘要
目的探讨穿刺引导架在CT导向活检和介入治疗中的应用。方法对468例患者应用穿刺引导架行CT引导介入活检或治疗，其中110例接受穿刺活检，358例接受穿刺治疗；胸部病变192例，腹部病变276例，病灶大小2～15cm。穿刺前行CT薄层扫描确定皮肤进针点、确定双向进针角度α、θ和深度d等数据，放置穿刺引导架，局麻后将穿刺针刺人皮肤，调整穿刺针体与CT机架（α）定位激光线重合，穿刺角度为θ。CT扫描确认穿刺针瞄准病灶靶点，将穿刺针刺入至进针深度，命中靶点。结果总体穿刺命中率为100％，一步命中率为96．79％，定位扫描开始至穿刺命中平均8．4min；胸部穿刺气胸发生率为1．56％。结论穿刺引导架应用于CT介入诊疗，使操作准确、安全、便捷，值得推广。
Objective To evaluate the application of a puncture guidance supporter in CT guided biopsy and interventional therapy. Methods Totally 468 patients underwent CT interventional biopsy （n=10） or treatment （n=358） using a puncture guidance supporter. The size of lesions was 2 15 cm. CT scanning was performed to determine the entry point, data of bi-directional needle angle a, 0 and depth d before operation. After local anesthesia, the needle was punctured into skin through the puncture guidance supporter, the needle overlap CT positioning laser line in tilt angle （a） was adjusted and the puncture direction at angle 0. After CT scanning confirmed the needle aiming at target lesion, punctures were performed with the needle into the depth to hit the target. Results The total puncture hit rate was 100%, and one step hit rate was 96.79%. The average time from location scanning to hit the target was 8.4 min. The incidence of pneumothorax occurred in thorax management was 1.56%. Conclusion The application of puncture guidance supporter in CT interventional diag nosis and treatment makes operation more accurate, safe and convenient.
