CT引导下经皮同轴穿刺活检诊断颈部病变20例

CT-guided percutaneous coaxial biopsy for the diagnosis of neck lesions

目的评价CT引导下经皮同轴穿刺活检诊断颈部病变的技术成功率、诊断正确性及安全性。方法 2005年4月—2012年10月采用CT引导下经皮穿刺活检术对20例颈部病变行经皮穿刺同轴活检术,分析穿刺成功率及活检准确性。结果 20例颈部病变患者在CT引导下接受20次经皮同轴穿刺活检,其中颈部软组织病变12例,颈椎病变8例。CT证实20次经皮穿刺的穿刺针皆位于颈部病变内,穿刺技术成功率100%。19次活检病理结果与临床最终诊断一致,诊断准确率95%。所有病例无穿刺相关的严重并发症发生。结论 CT引导下经皮同轴穿刺活检术诊断颈部病变是安全、准确、微创的介入诊断技术。

Objective To assess the technical success rate,diagnostic accuracy and clinical safety of CT-guided percutaneous coaxial biopsy for neck lesions.Methods During the period from Apr.2005 to Oct.2012,CT-guided percutaneous coaxial biopsy was carried out in 20 patients with neck lesions.The technical success rate and the diagnostic accuracy were analyzed.Results A total of 20 percutaneous coaxial biopsies were performed in 20 patients with neck lesions,including 12 cervical soft tissue lesions and 8 cervical vertebral lesions.CT scanning proved that the biopsy needle was right within the neck lesion in all 20 biopsy procedures.Technical success rate in this series was 100%.The pathological results of 19 biopsies were completely in agreement with the final clinical diagnoses,with a diagnostic accuracy of 95%.No serious puncture-related complications occurred.Conclusion CT-guided percutaneous coaxial biopsy is a safe,accurate and minimally-invasive interventional technique for the diagnosis of neck lesions.
