Abstract:: Abstract: Objective To analyze the application of three-dimensional reconstruction using Mimics software and CT-guided coil localization in surgery of pulmonary small nodules. Methods All of the 100 enrolled patients with pulmonary small nodules underwent video-assisted thoracoscopic surgery. Three-dimensional reconstruction using Mimics software and coil localization were carried out in experimental group (n=50) but not in control group (n=50) before surgery. The forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and maximal voluntary ventilation (MVV) were measured using spirometer before surgery and on day 7 after surgery and the surgical indicators were compared. Results The operation time, intraoperative blood loss, drainage time, drainage volume, volume of lung tissues removed by wedge-shaped resection, number of occluder nail boxes, and total hospitalization cost in experimental group were significantly shorter/less/smaller than those in control group (P<0.05). After surgery, FVC, FEV1 and MVV increased in both groups, and the increases were significantly higher in experimental group than in control group (P<0.05). Conclusion The combination of three-dimensional reconstruction using Mimics software and CT-guided coil localization can provide accurate guidance for surgery of pulmonary small nodules, enhance surgical safety, and improve the patients pulmonary function.
