Deep Insight软件术前肺部支气管血管成像的真实性研究

A Study on the Authenticity of Preoperative Pulmonary Bronchial Angiography by DeepInsight Software

背景与目的精准肺段切除术已成为肺结节及早期肺癌外科治疗的首要选择,而其手术重点及难点则在于对病灶的精准定位与切除。DeepInsight为我中心与东软公司共同研发的精准肺部手术辅助软件,可术前明确肺部精确解剖,定位肺部病灶位置,此次研究即为验证DeepInsight肺部支气管血管成像辅助手术的真实性及可靠性。方法本研究共纳入了2016年8月1日-2019年12月31日江苏省人民医院胸外科收治的1,020例预行手术治疗患者,所有入组患者肺部结节直径<2.0 cm,术前均行肺结节计算机断层血管造影(computed tomographic angiography,CTA)检查,使用DeepInsight软件术前进行术侧肺部支气管血管成像,识别受累肺段、肺动脉及肺静脉,2位胸外科医师采用5分法独立评估受累肺血管的可视性情况,χ^(2)检验评估观察者间的一致性。此外,术侧肺部血管虚拟成像及真实解剖对比,由2名胸外科主任医师最终决定受累肺血管情况。结果1,020例患者术前运用Deep Insight软件术侧肺部虚拟成像血管与术中受累血管的数量及空间解剖关系之间的差异无明显统计学意义,观察者间的一致性均相当满意。结论Dee术中进行p Insight软件肺部支气管血管虚拟成像可精准具化肺部真实血管情况,辅助肺段切除术的完成。

Background and objective Precise segmentectomy has become the first choice of surgical treatment for pulmonary nodules and early lung cancer,and the key and difficult point of the surgery lies in the precise location and resection of the lesion.DeepInsight is an auxiliary software for precise lung surgery jointly developed by our center and Neusoft Company,which can determine the precise anatomy of the lung and locate the location of lung lesions before operation.This study is to verify the authenticity and reliability of DeepInsight lung bronchial angiography assisted surgery.Methods In this study,1,020 patients with pulmonary nodules<2.0 cm in diameter were included in the Department of Thoracic Surgery Jiangsu Provincial People’s Hospital from August 1,2016 to December 31,2019.Computed tomographic angiography(CTA)was performed on all the included patients before surgery.The DeepInsight software was used to perform preoperative bronchial angiography on the operative side of the lung to identify the affected pulmonary segments,pulmonary arteries and pulmonary veins.Two thoracic surgeons independently assessed the visibility of the affected pulmonary vessels using the 5-point method,and theχ^(2)test assessed the consistency between observers.In addition,virtual imaging and real anatomy of pulmonary vessels on the operative side were performed during the operation,and the involved pulmonary vessels were finally determined by 2 chief physicians of thoracic surgery.Results There were no statistically significant differences between the number and spatial anatomy of the vessels involved in the pulmonary virtual imaging using DeepInsight software before operation and the number of vessels involved during operation in 1,020 patients.And the consistency among observers is quite satisfactory.Conclusion The DeepInsight software virtual imaging of pulmonary bronchial vessels can accurately reconstruct the actual pulmonary vessels and assist the completion of pulmonary segmental resection.
