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 To diagnose and treat the anterior mediastinum tumor, we need to get cytology and summarize the positive rate and coincidence rate of benign and malignant lesions. Methods According to the recent chest X-ray or CT film to determine the location of the anterior mediastinum puncture. If close to the blood vessels, the application of simulated positioning machine or CT machine guidance, are used ordinary lumbar puncture, drawing, sending cytology. Results The positive rate of puncture was 70 4 9%. The detection rates of benign and malignant lesions were 38 89% and 83 72% respectively, with significant difference (P <0.01). The coincidence rates of puncture results and surgery confirmed benign and malignant tumors were 35.29% and 68.42%, respectively (P <0.05). Conclusion Percutaneous puncture of mediastinal mass quickly and safely. The detection rate of malignant lesions, in line with the rate were higher than the benign lesions.
