Objective: This study aimed to evaluate the effectiveness of three-dimensional CT bronchial angiography (3D-CTBA) in facilitating precise lung segmental resection.
Methods: A total of 80 patients with peripheral lung nodules undergoing anatomical lung segmentectomy were randomly divided into two groups: a control group (n = 40) and a study group (n = 40). The control group received surgical treatment based on chest CT prompts and traditional lung segmentation, while the study group's chest CT imaging data were reconstructed into 3D images before surgery, followed by lung segmentectomy. Surgical parameters and complication rates were compared between the two groups.
Results: The study group exhibited significantly shorter operation time, drainage time, and hospitalization time, as well as reduced intraoperative bleeding, lung tissue resection size, and drainage volume, compared to the control group (P < .05). Hospitalization costs did not differ significantly between the two groups (P > .05). The incidence of lung infection, pulmonary atelectasis, and arrhythmia showed no significant difference between the groups (P > .05). However, the study group demonstrated significantly lower rates of hemoptysis and lung leakage compared to the control group (P < .05). There was no significant difference in the composition of postoperative pathological staging between the two groups (χ2 = 0.721, P > .05).
Conclusions: The application of 3D-CTBA technology provides clear visualization of the lung's anatomical structure and contributes to enhanced safety and effectiveness in thoracoscopic lung segmental precision resection.
