3D打印技术协助手术切除肺部磨玻璃样结节1例报告

Surgical Planning in Ground-Glass Opacity of Lung Using 3D Printing Technology:a Case Report

患者女性,59岁,胸部CT及正电子发射计算机断层扫描检查结果显示,右肺上叶一直径9 mm大小的磨玻璃样结节,未转移。拟对其进行手术治疗。术前采用3D打印技术重建模型的方法重建肺部解剖结构,根据模型制定手术方案。在胸腔镜辅助下,对该患者右肺上叶尖段实施肺段切除术。冰冻切片检查结果提示微浸润性腺癌。由于该患者病灶的切缘>2 cm,未进行进一步切除。随后,对纵隔淋巴结进行系统采样。病理组织学检查结果显示,微浸润性腺癌(pT1aN0M0)。3D打印技术在肺部磨玻璃样结节的手术切除中可能有助于制定手术方案。

A59-year-old female patient with a ground-glass opacity（GGO）in the right upper lobe of lung was prepared for surgery.CT and positron emission computed tomography（PCT）of thorax revealed a 9 mm GGO in the right upper lobe,with no metastasis.A3 D printing of the right lung was performed to simulate the lesion.The surgical plan was made according to the model.A video-assisted thoracoscopic segmentectomy of apical segment of right upper lobe was performed.A microinvasive adenocarcinoma was proved by frozen section.Since the cutting border was larger than 2 cm from the lesion,no further resection was performed.Subsequently,a systemic mediastinal lymph node sampling was performed.Final pathology demonstrated a pT1aN0M0 microinvasive adenocarcinoma of the right upper lung.This case report illustrated that the 3D printing technology may be helpful in the procedure of surgical planning in resection of GGO.
