目的 为明确纵隔淋巴结肿大的性质 ,进行CT定位经纤维支气管镜纵隔淋巴结针吸活检术 (CT guidedtransbronchialneedleaspirationbiopsy ,CT TBNA)的研究。方法 根据纵隔淋巴结分区定位标准 ,对原发性肺癌 (5 4例 )伴纵隔淋巴结肿大、恶性淋巴瘤 (5例 )、纵隔脓肿 (3例 )、炎性淋巴结肿大 (11例 )共 73例 15 8枚纵隔肿大淋巴结行CT TBNA穿刺活检。结果 CT扫描证实穿刺针在全部15 8枚淋巴结内 ,其中 86 %(136 / 15 8)的淋巴结抽吸物经病理检查获得了病理组织学和 (或 )细胞学诊断 ,未发生严重并发症。结论 CT TBNA的标准是可靠的 ,穿刺操作安全有效 ,对确定纵隔淋巴结肿大性质和肿瘤分期有重要意义。
Objective To determine the nature of mediastinal lymphadenopathy by CT-guided transthoracic bronchoscopic mediastinal lymph node biopsy (CT TBNA) studies. Methods According to the regionalization criteria of mediastinal lymph nodes, primary lung cancer (54 cases) with mediastinal lymphadenopathy, malignant lymphoma (5 cases), mediastinal abscess (3 cases), and inflammatory lymphadenopathy (11 cases) total 73 Example 15 8 mediastinal lymph nodes underwent CT TBNA biopsy. Results The CT scan confirmed that the puncture needle was in all 15 8 lymph nodes. Among them, 86% (136/158) lymph node aspirate obtained histopathological and/or cytological diagnosis by pathological examination. No serious complications occurred. Conclusion The standard of CT TBNA is reliable, and the puncture procedure is safe and effective. It is of great significance to determine the nature of lymph nodes enlargement and tumor staging.
