Objective  To investigate the application value of single-port thoracoscopy combined with three-dimensional CT bronchography and angiography (3D-CTBA) in anatomical segmentectomy of lungs.

  Methods  A total of 46 patients with pulmonary nodules who underwent single-port thoracoscopic anatomical segmentectomy and their clinical data were retrospectively analyzed.

  Results  All patients underwent 3D-CTBA before operation, and segmentectomy was performed under single-port thoracoscopy without thoracotomy, extended lobectomy and perioperative death.The operative time was (139.3±32.5) min, the intraoperative blood loss was (84.5±45.3) mL, the postoperative chest tube extubation time was (5.5±1.3) days, the postoperative hospital stay was (7.1±2.8) days and the number of lymph nodes dissected was (10.2±3.4).Postoperative pathology showed primary lung adenocarcinoma in 39 cases, metastatic carcinoma in 3 cases and granuloma in 4 cases. After operation, two patients had pulmonary air leakage more than 5 days, which was improved after continuous drainage; two cases had pulmonary infection, and were improved after anti-infection treatment; arrhythmia occurred in 3 cases.

  Conclusion  Single-port thoracoscopy combined with 3D-CTBA anatomical segmentectomy is safe and feasible, which is conducive to the rapid recovery of patients.
