摘要
目的探讨C臂CT引导下靶向穿刺技术在非血管介入诊疗中的应用价值方法以2010年7-9月在郑州大学第一附属医院放射与介入科诊治的、具有完整临床资料的31例患者为研究对象,在C臂CT引导下行经皮穿刺活检术或经皮穿刺介入治疗,观察分析并发症及活检阳性率。结果 13例患者在C臂CT引导下行经皮穿刺介入治疗,其中肝细胞癌射频消融术2例,盆腔脓肿、肝脓肿穿刺引流各1例,肝癌经皮穿刺乙醇消融术4例,肾囊肿、肝囊肿穿刺乙醇硬化各2例,胰腺假性囊肿穿刺置管引流1例。余18例行病理活检,其中4例为肝活检、7例为肺活检、2例纵隔占位活检、骨与软组织活检4例,颈部肿块活检1例。所有患者术程顺利,术中无技术相关并发症发生。活检病例中1例肺活检为假阴性,17例获阳性结果,总阳性率为94.4%。结论 C臂CT引导下靶向穿刺技术实现了CT和X线透视优势互补,实时透视显示路径图指导穿刺、治疗;不仅优化了介入工作流程、节省手术时间,而且穿刺成功率较高、技术安全、值得推广应用。
Objective To investigate the clinical value of C-arm CT-guided targeted puncturing technique in performing non,vascular interventional biopsy or interventional therapy.Methods Thirty,one patients,who were encountered in authors＇ hospital during the period from July 2010 to September 2010,were involved in this study.C,arm CT-guided percutaneous targeted puncturing biopsy or interventional therapy was performed in all 31 patients.All patients had complete clinical data.The complications and positive rate of biopsy were recorded and analyzed.Results Under C-arm CT-guidance,percutaneous interventional therapy was carried out in 13 patients.The interventional procedures included radiofrequency ablation therapy for hepatic cellular carcinoma（n = 2）,pelvic abscess draining（n = 1）,hepatic abscess draining（n =1）,ethanol injection for liver cancer（n = 4）,sclerotic therapy with ethanol injection for renal cyst（n = 2）,sclerotic therapy with ethanol injection for liver cyst（n = 2） and catheter-indwelling drainage for pancreatic pseudocyst（n = 1）.Percutaneous interventional biopsy was performed in the remaining 18 cases,including liver（n = 4）,lung（n = 7）,mediastinum（n = 2）,bone and soft tissue（n = 4） and neck mass（n = 1）.All the procedures were successfully accomplished,no technique,related complications occurred during the operation.For biopsy examination in 18 cases,the positive rate was 94.4%（17/18）and false,negative result was seen in one case with lung lesion.Conclusion The percutaneous targeted puncturing technique with C,arm CT-guidance combines the advantages of both CT scanning and fluroscopy.The use of real,time road,mapping function can effectively guide the puncturing and therapeutic management,which can not only optimize the workflow,save the operation time,but also improve the success rate and technical safety.Therefore,it is of great value to popularize this targeted puncturing technique.
