摘要
目的评价CT引导下椎弓根后外侧途径经皮穿刺活检对胸椎病变诊断的成功率、诊断正确性及临床应用价值。方法在CT引导下采用经椎弓根后外侧途径对12例胸椎病变行经皮穿刺活检。结果 12例病变接受13次活检,其中1例接受2次穿刺活检。CT证实13次穿刺活检,活检针均在病灶内,其中12次活检病理结果与临床最终诊断相一致,诊断准确率92.3%。所有病例无穿刺相关的严重并发症。结论 CT引导下经椎弓根后外侧途径穿刺活检诊断胸椎病变是安全、准确、微创的介入诊断技术。
Objective To discuss the technical successful rate of CT-guided percutaneous biopsy via extrapedicular posterolateral approach,and to determine its diagnostic accuracy and clinical usefulness for the thoracic vertebral lesions.Methods CT-guided percutaneous biopsy via extrapedicular posterolateral approach were performed in 12 patients with thoracic vertebral lesions.The technical successful rate and the diagnostic accuracy were analyzed.Results A total of 13 percutaneous needle biopsies via extrapedicular posterolateral approach were performed in 12 patients with thoracic vertebral lesions.One patient received twice puncture exams.The puncture biopsy needle was placed into the spinal lesions,which was conformed by CT scan.The pathological results of twelve biopsies were completely in agreement with the final clinical diagnoses,with a diagnostic accuracy of 92.3%.No serious puncture-related complications occurred.Conclusion CT-guided percutaneous biopsy via extrapedicular posterolateral approach is a safe,accurate and minimally-invasive interventional technique for the diagnosis of thoracic vertebral lesions.
