目的评价多层螺旋CT导引下经皮肺穿刺活检对肺部占位病变的诊断价值及应用的安全性。方法在多层螺旋CT导引下分别对50例肺部占位病变穿刺活检,对采集的标本行病理学检查,术后行CT扫描明确是否有气胸、出血等并发症,分析取材准确性及并发症出现率。结果多层CT穿刺活检组50例均穿刺成功,取得满意组织并确诊48例,其中恶性病变38例,良性病变10例。并发症出现率4%。结论多层螺旋CT引导下穿刺活检成功率和准确率较高,并发症轻,可作为肺部肿块定性诊断的首选方法,值得临床推广。
Objective To evaluate the diagnostic value and safety of pulmonary space-occupying lesions guided by multi-slice spiral CT guided percutaneous lung biopsy. Methods Fifty patients undergoing lung space-occupying lesions biopsy were examined under multi-slice spiral CT. Pathological examination was performed on the collected specimens. Complications of pneumothorax and hemorrhage were determined by CT scan after operation. Complication rate. Results All the 50 cases of multi-slice CT biopsy group were successfully punctured, and 48 cases were confirmed with satisfactory organization, including 38 cases of malignant lesions and 10 cases of benign lesions. Complication rate of 4%. Conclusion The success rate and accuracy of biopsy guided by multislice spiral CT are high, and the complication is mild. It can be used as the first choice of qualitative diagnosis of lung mass, which is worthy of clinical promotion.
