经皮穿刺纵隔部位肿块活检的临床价值——附61例报告

Clinical Value of Percutaneous Needle Aspiration Biopsy of Mediastinal Location Tumor ——Enclosed Herewith 61 Cases of Reports

目的 对前纵隔肿块 ,临床为明确诊断及治疗需要取得细胞学 ,总结其良恶性病变穿刺的阳性率及符合率。方法 依新近的胸片或CT片确定的前纵隔肿块位置进行穿刺。若靠近血管 ,则应用模拟定位机或CT机引导 ,均采用普通腰穿针穿刺、取材、送细胞学检。结果 穿刺阳性率 70 4 9% ,良恶性病变检出率分别为 38 89% ,83 72 % ,有极显著差异 (P <0 0 1)。穿刺结果与手术证实良恶性肿瘤的符合率分别为 35 2 9% ,6 8 4 2 % ,有显著差异 (P <0 0 5)。结论 经皮穿刺纵隔肿块迅速、安全。恶性病变的检出率、符合率均高于良性病变。

Objective In order to confirm the diagnosis in clinic and have need for treatment,percutaneous needle aspiration biopsy(PNAB) was performed in anterion mediastinal tumor.This article reported the positive rate and coincidence rate of PANB of mediastinal tumor in benign and malignant pathological changes.Methods We performed PANB for anterior mediastinal tumor whose position was defined with recent chest films or CT films.If the position of anterior mediastinal tumor is near to the blood vessel,the PANB was performed under simulated location machine or CT machine guidance.The mediastinal nodules were biopsied and were used for cyto and histopathologic examination.Results The positive rate of PANB was 70 49%.The detection rate of benign or malignant pathological changes were 38 89%,83 72%,respectively,and there was a significant differece( P <0 01).The rates of benign or malignant tumor proved by operation were 35 29%,68 42%,respectively,and there was a significant difference( P <0 05).Conclusion PNAB is quick and saft with high detection rate and coincidence rate for malignate pathological changes.
