肺微小磨玻璃结节标本充气下CT引导下穿刺定位

摘要

目的：探讨对手术切除的肺部标本持续充气下行CT引导下肺内微小磨玻璃结节（GGN ）穿刺定位的临床应用价值。方法：对12例有肺内微小GGN （均小于10mm）的手术切除标本，在持续充气下行CT 引导下细针穿刺病灶，然后将带有穿刺针的标本送至病理科，根据穿刺针的位置来确定病灶的位置并进行取材和组织学观察。结果：12例肺内GGN的手术切除标本在持续充气后肺组织膨胀满意，行CT扫描均能清晰显示肿块，穿刺定位后指导病理科医师顺利找到病灶、成功取材并获得了准确的病理诊断。结论：持续充气下行 CT 引导下肺内微小磨玻璃结节穿刺定位可准确定位手术切除标本中病灶的位置，为病灶的取材和诊断提供帮助。%Objective:To assess the clinical value of CT-guided fine needle puncture of ground-glass micro-nodule (micro-GGN)in aerated lung specimen.Method:Twelve lung specimens with micro-GGN (less than 10mm)obtained just after the surgery were aerated by air aerator.The lesions were localized by CT-guided fine needle puncture.Then the speci-mens were taken to department of pathology for pathologic sampling and histological examination.Results:All of these 12 lung specimens were aerated successfully with good quality of CT images to show the micro-GGN.The micro-GGNs were easily to be found according to the location of the needles,and then were successfully sampled,and accurate histological diagnosis was obtaind.Conclusion:There was important clinical value of CT-guided fine needle puncture of aerated lung specimen for localization of micro-GGNs.
