摘要

目标。目的:探讨ct引导下胸腔活检对肺部及纵隔恶性肿瘤的诊断价值。材料和方法。回顾性分析32例ct引导下的经胸活检。肺和纵隔肿块疑似恶性肿瘤,在可操作区域大小大于2.0 cm,是ct活检的指征,并进行额外的印象涂片检查。一个循序渐进的过程包括用CT定位目标,通过放射治疗程序进行标记,并执行该程序。细胞学和组织学资料进行评价和比较。通过对32例肺肿块(75±7.7%)和纵隔肿块(25±7.7%)的手法分析,证实了该手术的技术有效性,手术时间为37±9分钟。印迹涂片细胞学检查(81.3±6.9%)和组织学检查(71.9±8%)确诊(p < 0.05)。两种方法测定结果的一致性为53.1±8.8%。69.6±9.6%的患者对材料进行免疫组化分析。21.9±7.3%患者出现手术并发症(气胸、咯血)。细胞学检查使计划的组织学和免疫组织化学分析的结果具有很高的概率预测性。ct引导下的经胸穿刺是诊断肺部和纵隔恶性肿瘤的一种非常有效的方法,它可以在81%的病例中进行形态学表征。

Еffectiveness of ct-guided transthoracic biopsy
Objective. To evaluate the effectiveness of CT-guided thoracic biopsy in the diagnosis of lung and mediastinal malignancies.Materials and methods. A retrospective analysis of 32 cases of CT-guided transthoracic biopsy was performed. Lung and mediastinal masses suspicious for malignancy with a size of more than 2.0 cm in the area available for manipulation were the indication for Cor-biopsy with additional examination of impression smears. A step-by-step procedure involved CT positioning of the object, marking by the radiation therapy program, and performing the procedure. The cytological and histological materials were evaluated and compared.Results. The analysis of manipulations performed in 32 patients with lung masses (75±7.7%) and mediastinal masses (25±7.7%) proved the technical effectiveness of the procedure, which lasted 37±9 minutes. The diagnosis was confirmed by cytological analysis of impression smears in 81.3±6.9% of cases, and using histological methods – in 71.9±8% (p>0.05). The agreement between the results obtained by both methods was 53.1±8.8%. Immunohistochemical analysis of the material was performed in 69.6±9.6% of patients. Procedural complications (pneumothorax and hemoptysis) were observed in 21.9±7.3% of patients. Cytological examination allowed the results of a planned histological and immunohistochemical analysis to be foreseen with a high degree of probability.Conclusion. CT-guided transthoracic puncture is a highly effective method of diagnosing lung and mediastinal malignancies, which allows their morphological characterization to be done in 81% of cases.
