Abstract
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.
