ObjectiveThree-dimensional computed tomography bronchography and angiography (3D-CTBA) can provide detailed imaging information for pulmonary segmentectomy. This study aimed to investigate the safety and effectiveness of 3D-CTBA guidance of anatomical segmentectomy of the right upper lobe (RUL).MethodsThis was a retrospective analysis of anatomical segmentectomy of the RUL at the Thoracic Surgery Department of the Fourth Hospital of Hebei Medical University from December 9, 2013, to June 2, 2021. Preoperatively, all patients underwent contrast-enhanced CT of the chest (to determine the size of the pulmonary nodule) and a lung function test. 3D-CTBA has been performed since 2018; patients with vs. without 3D-CTBA were compared. Segmentectomy was performed according to nodule location.ResultsOf 139 patients (46 males and 93 females, aged 21–81 years), 93 (66.9%) completed single segmentectomy, 3 (2.2%) completed single subsegmentectomy, 29 had combined subsegmentectomy, 7 had segmentectomy combined with subsegmentectomy, and 6 had combined resection of two segments. Eighty-five (61.2%) patients underwent 3D-CTBA. 3D-CTBA cases had decreased intraoperative blood loss (67.4 ± 17.6 vs. 73.1 ± 11.0, P = 0.021) and shorter operation time (143.0 ± 10.8 vs. 133.4 ± 20.9, P = 0.001). 3D-CTBA (Beta = −7.594, 95% CI: −12.877 to −2.311, P = 0.005) and surgical procedure (Beta = 9.352, 95% CI: 3.551–15.153, P = 0.002) were independently associated with intraoperative blood loss. 3D-CTBA (Beta = −13.027, 95% CI: −18.632 to 17.422, P |
