Abstract:
Objective To study the clinical value of virtual segmentectomy based on three-dimensional computed tomography bronchography and angiography (3D-CTBA) in thoracoscopic segmentectomy for early-stage lung cancer. Methods Totally 18 patients received thoracoscopic segmentectomy from July 2015 to July 2016 were performed virtual segmentectomy based on 3D-CTBA. The preoperative planning depended on the simulation result. Results All of the 18 cases(1 right Sl, 2 right S3, 3 right S6, 1 right S8 +9, 1 right S9 + 10, 3 left S1 +2 +3, 3 left S4 +5, 4 left S6 segmentectomies)were received thoracoscopic segmentectomy successfully. The mean operation time and intraoperative blood loss were (126.8士19.4) mins and(76.6±21.4) ml respectively. Pathological examination revealed no residual tumor cells at the surgical margins and no lymph node metastases in any patients. The actual surgical margins were all larger than 2 cm(2.37±0.39)cm. Conclusion Virtual segmentectomy based on 3D-CTBA can non-invasively visualize the relationship between the safe margin and segmental vessels and bronchi. It facilitates the preoperative planning of suitable segmentectomy procedure for patients with early-stage lung cancer.
