目的 探讨超声引导下应用自动活检枪经皮对纵隔肿瘤活检的临床应用价值。方法 46例纵隔肿块患者 ,在B超引导下应用自动活检枪 ( 18G切割针 )行肿块穿刺活检 ,标本用 10 %福尔马林固定后送病理检查。结果 46例纵隔肿瘤均一次取材成功 ,根据取材标本获得确切病理分型诊断者 41例 ,占 89%,无 1例发生出血和气胸、呼吸困难等并发症。结论 B超引导下经皮纵隔肿瘤穿刺活检可以获得较高的病理诊断阳性率 ,为临床确诊纵隔肿瘤的好方法
Objective To investigate the clinical value of ultrasound-guided percutaneous transcranial tumor biopsy using automatic biopsy gun. Methods Forty - six patients with mediastinum masses underwent B - guided biopsy with autopsy gun (18G needle). The specimens were fixed in 10% formalin and sent for pathological examination. Results All the 46 mediastinal tumors were obtained successfully. According to the obtained specimens, 41 cases (89%) were diagnosed according to the exact pathological classification. No bleeding, pneumothorax or dyspnea were found in 1 case. Conclusion Percutaneous mediastinal biopsy guided by B-ultrasonography can obtain a high positive rate of pathological diagnosis, which is a good method for clinical diagnosis of mediastinal tumors
