Abstract

Background: This retrospective study aimed to summarize the application of 3-dimensional(3D) reconstruction via modified pulmonary artery computed tomography angiography(CTA), as well as to compare the surgical outcomes of 3D versus high resolution CT(HRCT) in anatomic pulmonary segmentectomy(APS).

Methods: A total of 93 patients who underwent thoracoscopic APS were enrolled in the study. They were divided into 3D group (n = 30) and HRCT group (n = 63), and than matched at 1:1 ratio using the propensity score matching (PSM) method. Clinical characteristics, surgical status, and postoperative recovery were compared between two groups, additionally, variations of segmental structures were summarized.

Results: 60 cases were matched by PSM with 30 cases in each group. There were no significant differences between two groups in clinical characteristics, intraoperative blood loss and postoperative recovery (including total chest drainage, length of postoperative hospital stay)(P > 0.05 for all). 8(26.7%) patients in 3D group manifesting unique variations of segmental structures underwent anatomical segmentectomy accurately. Despite the 3D group exhibited higher anatomic variations compared to the HRCT group, it demonstrated shorter operation times and lower incidence of pulmonary infection. (P < 0.05 for all).

Conclusion: Preoperative 3D reconstruction has advantages in APS, particularly for patients with complex anatomic variations. Reconstruction via modified pulmonary artery CTA is also feasible for preoperative planning and intraoperative navigation in thoracoscopic APS.

改良肺动脉计算机断层血管造影三维重建在解剖性肺段切除术中的应用。

背景：本回顾性研究旨在总结改良肺动脉计算机断层血管造影（CTA）三维重建的应用，并比较3D与高分辨率CT（HRCT）在解剖性肺段切除术（APS）中的手术效果。方法：共纳入93例胸腔镜下APS患者。将患者分为3D组（n = 30）和HRCT组（n = 63），采用倾向评分匹配法（PSM）按1:1比例进行匹配。比较两组患者的临床特点、手术状态及术后恢复情况，并总结节段结构的变化。结果：PSM配对60例，每组30例。两组患者的临床特征、术中出血量及术后恢复情况（包括胸腔总引流、术后住院时间）比较，差异均无统计学意义（P < 0.05）。3D组有独特节段结构变化的患者8例（26.7%）准确行解剖节段切除术。尽管与HRCT组相比，3D组显示出更高的解剖变异，但它显示出更短的手术时间和更低的肺部感染发生率。结论：APS术前3D重建具有优势，特别是对于解剖变异复杂的患者。改良肺动脉CTA重建对于胸腔镜APS术前规划和术中导航也是可行的。
