多层螺旋CT在经皮穿刺肺组织活检中的应用价值

The Value of MSCT in Percutaneous Transthoracic Lung Biopsy

目的探讨多层螺旋CT(MSCT)引导下经皮穿刺肺组织活检的技术方法,并评价MSCT在经皮穿刺肺组织活检中的应用价值。资料与方法对42例患者的42个肺部病灶进行MSCT引导下经皮穿刺肺活检。结果42个病灶均成功穿刺(成功率为100%)。肺外周小病灶的一次穿刺成功率为88.2%(15/17),肺门部病灶的一次穿刺成功率为86.7%(13/15)。病理检出40例,诊断成功率和活检准确率均为95.2%。术后并发肺出血2例,发生率为4.8%;气胸2例,发生率为4.8%。结论MSCT引导不仅能提高经皮穿刺肺外周部小病灶和肺门部病灶的技术成功率、诊断成功率和活检准确性,而且能减少并发症的发生。

Objective To introduce MSCT guided percutaneous transthoracic lung biopsy technique and to evaluate the application of this technique. Materials and Methods 42 patients with 42 pulmonary lesions were performed percutaneous transthoracic lung biopsy under the guidance of 16 slices MSCT. Results All the 42 patients were performed percutaneous transthoracic lung biopsy successfully. The biopsy achievement rate was 100%, Onetime achievement rate was 88.2% for the small pulmonary peripheral lesions and 86.7% for the lesions around the pulmonary hilus. 40 cases obtained pathological diagnosis after biopsy. The diagnostic success rate and the accuracy of biopsy both were 95.2%. Complications including 2 cases of pneumothorax（4.8% ） and 2 cases of pneumorrphagia（4.8% ） occurred. Conclusion MSCT can not only improve the technical achievement rate, the diagnostic success rate and the accuracy of biopsy for the small pulmonary peripheral lesions and the lesions around the pulmonary hilus, but also reduce the complications.
