CT透视导向胸部病变穿刺活检

CT fluoroscopy-guided percutaneous thoracic puncture biopsy

目的 探讨CT透视导向胸部病变穿刺活检技术及其临床意义。方法 76例胸部病变穿刺 ,其中肺部 6 8例 ,纵隔 5例 ,胸膜 3例。结果 76例穿刺活检病灶成功率 10 0 %。诊断准确率 96 .1%(73 76 ) ,其中恶性病变诊断准确率 97.9% (4 7 4 8) ,良性病变诊断准确率 92 .3% (2 6 2 8)。并发气胸 2 4例(31.6 % )。结论 ①CT透视技术集合了X线透视和常规CT两者的优点 ;②对良、恶性病变诊断正确率很高 ,具有重要的临床意义。

Objective To study the technique and clinical significance of percutaneous thoracic biopsy using CT fluroscopic guidance.Methods 76 cases including 68 lung nodules, 5 mediastinal masses and 3 pleural lesions were undergone this procedure. Results The successful rate of the procedure was 100% for all the 76 cases. The diagnostic accuracies were 97.9% for malignant lesions (47/48), 92.3% for benign lesions (26/28), with a total accuracy of 96.1%. The complication of pneumothorax was presented in 24 cases of the total members. Conclusions ① The technique of CT fluoroscopy prosseses the virtue of x-ray fluoroscopy and CT. ② Because of the diagnostic high accuracy for malignant and benign lesions, percutaneous biopsy under CT fluoroscopic guidance have important clinical significance for diagnosis of thoracic lesions.
