CT透视引导下胸部小病灶穿刺活检的临床价值

Clinical value of CT fluoroscopy guided percutaneous needle aspiration biopsy of small pulmonary nodules

目的探讨CT引导胸部小病灶穿刺活检技术及诊断价值。方法 50例胸部小病灶(<3 cm)在CT引导下采用自动切割式活检针穿刺活检。结果50例胸部肿块穿刺活检病灶取材成功100%。胸部肿块穿刺活检的诊断准确率96%(48/50),对恶性病变诊断准确率97.5%(39/40),良性病变为90%(9/10)。并发气胸2例,少量出血1例。结论 C T引导下穿刺活检是安全、有效的诊断手段,对于胸部病变诊断的准确率高,CT引导下胸部小病灶穿刺活检对胸部病变的诊断和治疗具有重要意义。

Objective To evaluate the diagnostic value of CT fluoroscopy guided percutaneous needle aspiration biopsy of pulmonary nodules.Methods 50 patients underwent CT fluoroscopy guided percutaneous needle aspiration biopsy of a pulmonary nodule（with a diameter less than 3 cm） and then underwent surgical resection.Results All 50 surgeries of CT fluoroscopy guided percutaneous needle aspiration biopsy of pulmonary nodules were successful（100%）.The accuracy rate of diagnosis of CT fluoroscopy guided percutaneous needle aspiration biopsy of large nodules was 96%（48/50）.The accuracy rate of diagnosis for malignant diseases was 97.5 %（39/40）,and 90%（9/10） for benign diseases.Only 2 cases of all the patients who underwent CT fluoroscopy guided percutaneous needle aspiration biopsy were complicated with pneumothorax and 1 case with mild bleeding.Conclusion CT fluoroscopy guided percutaneous needle aspiration biopsy is a safe and effective method for diagnosis of thoracic lesions with a high accuracy rate.It has crucial significance for the diagnosis and treatment of thoracic lesions.
