超声引导下经皮纵隔肿瘤穿刺自动活检的应用

Application of Ultrasound Guided Percutaneous Automatic Biopsy of Mediastinal Tumors

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 。

Objective To assess the value of ultrasound guided percutanuous automatic biopsy of mediastinal tumors.Method Forty-six consecutive biopsies were performed on forty-six patients suffered from mediastinal tumor included 14 thymomas,12 lymphomas,9 metastasis carcinomas,5 mediastinal lung carcinomas,3 teratomas,2 neuroblastomas,1 granulosa cell tumor.Under US guidance,a 18-guage core needle with automatic biopsy device was used.Specimen was fixed with 10% formaldehyde solution.Results The procedure of puncture was successful in all patients.The positive rate histologically was 89%(41/46).No complication (such as hemorrhage,pneumothorax and dyspnoea) was happened.Conclusion We consider that the ultrasound-guided percutaneous needle biopsy is a safe and reliable method for the histological diagnosis of mediastinal tumors.
