肺外周型占位性病变超声引导经皮穿刺活检的临床价值

目的 探讨彩色多普勒超声引导下肺外周型占位性病变经皮穿刺活检的成功率及其临床价值.方法 应用Bard活检枪及18 G内槽切割式活检针,在彩色多普勒超声引导下对57例经CT诊断的肺外周型占位性病变行经皮穿刺活检.结果 穿刺取材满意率为98%,与术后大体标本病理组织学检查及临床随访对比,穿刺活检诊断准确率为96.4%;57例患者穿刺术中及术后无严重并发症发生:3例自诉术后胸痛,1例痰中带血,1例气胸.结论 彩色多普勒超声引导经皮穿刺活检具有操作简便、取材满意率高,病理诊断准确率高及并发症少等优点,值得推广.

Clinical value of ultrasound-guided percutaneous puncture biopsy of lung peripheral lesions

Objective To investigate the successful rate and clinical value of color Doppler ultrasound- guided percutaneous puncture biopsy of lung peripheral lesions. Methods Fifty-seven patients with lung peripheral lesions confirmed by CT were biopsied by Bard gun and 18 G biopsy needle under the guidance of color Doppler ultrasound. Results The satisfied specimens obtained by puncture were achieved in 56 cases （98%）. Compared with the postoperative histopathological diagnosis and clinical follow-up, the consistency was 96.4%. No severe complications were found in all 57 cases during the puncture or after the puncture. Three cases complained of chest pain, 1 case was of bloody sputum and 1 case of aerothorax. Conclusion Color Doppler ultrasound-guided percutaneous puncture biopsy is safe with the characteristics of easy manipulation, good satisfied specimens, high pathological diagnosis rate and less complications, and is worthy of wide anolication.
