CT导向经胸穿刺活检108例报告

CT-Guided Percutaneous Transthoracic Biopsies

CT导向经胸穿刺活检108例;纵隔,肺门36例,周围肺野66例,胸膜6例。经手术证实和临床随访,恶性肿瘤的穿刺活检正确率为96％、良性肿瘤为54.5％、非肿瘤性病变为36.4％。4例并发症:2例气胸、2例轻微出血。无空气栓塞及肿瘤扩张。本文讨论了CT导向与电视监视,超声导向的比较,认为CT导向对深部小病灶以及组织结构重叠部位病灶比电视监视、超声导向为好。另外也分析了穿刺针与并发症的关系以及产生并发症的其它因素。并且评价了CT导向穿刺活检在临床诊断的作用。

CT-guided pereutaneous transthoracic biopsies were performed in 108 patients with mediastinal, hilar masses (36/108), peripheral lung lesions (66/108), and pleura (6/108). All cases were confirmed by surgery and follow up, The correct diagnosis were made in 96% of patients with malignent neoplasm, 54.4% with benign neoplasm, and 36.4% with nonneoplasm lesions. Complications were encountered in 4 patients: two of pneumothorax, and slight bleeding in the others. Compared with fluroscopy and sonography, the CT guidance is superior for demonstrating the deep small lesions and structure overlaped lesions. The correlation between the complications and needles, used along with other factors was discussed. Moreover, the clinical significance of CT-guided percutaneous transthoracic biopsy was evaluated.
