摘　　要：目的 评价计算机导航技术在肋骨肿瘤手术中的应用优势.方法 对5例肋骨肿瘤患者术前行病灶局部CT扫描,并进行肿瘤边界、切除设计.术中进行C型臂扫描与术前CT影像融合,为外科切除提供清晰的引导.结果 平均融合时间为58 min,4例切除术后标本显示均具有安全的边界,组织学证据表明肿瘤标本切缘均为阴性,1例怀疑肺癌骨转移患者在导航引导下顺利活检,取得病理.结论 计算机导航技术能够帮助外科医师更准确判定肿瘤边界,实施精确切除,减小损伤.Objective To evaluate the advantage of using computer navigation system in the resection of rib tumors.Methods We carried out rib tumor resection in 5 patients using computer navigation system.Preoperative CT of each patient was performed.The preoperation CT-based planning was made for every patient with the navigation system software including confirming the tumor surgical margin and designing resection margin.A C-arm scan was carried out intraoperatively.With image fusion of both data,tumor resection were performed under navigation image guidance.Results The mean time of image fusion was 58 minutes.Four tumor resection specimens showed safe and clear margins.Histological examination of all tumor specimens showed tumor-free margins.One patient who was suspected lung cancer with bone metastases was performed a biopsy under navigation image guidance and obtained a pathology diagnose successfully.Conclusion The computer navigation system helps surgeons determine the surgical margin,implement precision tumor resection and reduce surgical damage.
