Accurate localization and resection of small pulmonary nodules assisted by mixed reality technique

Abstract

Objective To explore the feasibility of using mixed reality technique to assist the accurate localization of pulmonary nodules. Methods A patient with a small pulmonary nodule in Department of Thoracic Surgery, Chinese PLA General Hospital was selected and underwent thoracoscopic pulmonary wedge resection with perfect preoperative examination and no absolute surgical contraindication. The chest CT in supine position was used to reconstruct the body surface and the target lesion before operation. The auxiliary line was drawn up and the hookwire localization was used to localize the target lesion. At last, the accuracy of localization was further verified by CT in the OR. Then the lesion was resected completely. Results The location of the lesion was accurate and the patient was discharged from hospital successfully 4 days after the surgery. Conclusions This paper reports a case of accurate localization of a small pulmonary nodule assisted by mixed reality technique. The localization process was smooth and accurate, which is expected to open a new chapter in the localization of small pulmonary nodules in thoracic surgery. The further exploration and application of this technology will bring more development and prospect for thoracic surgery. Key words: Mixed reality; Small pulmonary nodules; Accurate localization
