Computer navigation-guided excision of rib tumor / 中华胸心血管外科杂志

ABSTRACT

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.
