Application of Mimics Medical 21.0 Software in thoracoscopic anatomical sublobectomy

The anatomical structure of pulmonary segments is complex, and there are many anatomical variations, making the operation more difficult, so we used Mimics Medical 21.0 software for three-dimensional computed tomography bronchography and angiography (3D-CTBA), carefully formulated the surgical plan and on this basis completed the video-assisted thoracoscopic anatomical sublobectomy.A total of 38 patients with pulmonary nodules were selected and received video-assisted thoracoscopic anatomical sublobectomy after using Mimics Medica 21.0 software for 3D-CTBA.The mean operative duration was 158.42±20.21 minutes, and the operative hemorrhage was 97.66±22.37 mL. In pathological diagnoses, there were 5 benign cases (13.2%), 9 cases with atypical adenomatous hyperplasia (23.7%), 12 cases with adenocarcinoma in situ (31.6%), 11 cases with minimally invasive adenocarcinoma (28.9%) and 1 case with invasive adenocarcinoma (2.6%); 8.29±0.98 lymph nodes sampled had no metastasis. The chest tube drainage duration and postoperative hospital stay were 2.47±0.73 days and 5.47±0.73 days, respectively.Using Mimics Medical 21.0 software can quickly and accurately complete 3D-CTBA, which is beneficial to formulate a personalized anatomical sublobectomy surgical plan.
