Introduction This research aimed to explore the relationship between spinal characteristics and the length of the abdominal aorta in adult spinal deformity (ASD) patients who underwent corrective spinal surgery. We hypothesized that adjusting spinal alignment might affect the abdominal aorta's length. Methods This study included thirteen patients with ASD (average age: 63.0 ± 8.9 years; four males and nine females) who received spinal correction surgery. We measured both pre-operative and post-operative spinal parameters, including thoracolumbar kyphosis (TLK), and calculated their differences (Δ). The length of the aorta (AoL) was determined using an automated process that measures the central luminal line from the celiac artery's bifurcation to the inferior mesenteric artery. This measurement was made using contrast-enhanced computed tomography for three-dimensional aortic reconstruction. We compared the pre-operative and post-operative AoLs and their differences (Δ). The study examined the correlation between changes in spinal parameters and changes in AoL. Results Post-operatively, there was an increase in aortic length (ΔAoL: 4.2 ± 4.9 mm). There was a negative correlation between the change in TLK and the change in AoL (R = 0.45, p = 0.012, β = -0.21). No significant correlations were found with other spinal parameters. Conclusions The abdominal aorta can elongate by 4.8% after spinal corrective surgery in patients with ASD. The degree of elongation of the abdominal aorta is associated with spinal alignment correction.
引言 本研究旨在探讨接受脊柱矫正手术的成人脊柱畸形（ASD）患者的脊柱特征与腹主动脉长度之间的关系。我们假设调整脊柱排列可能会影响腹主动脉的长度。方法 本研究纳入了13例接受脊柱矫正手术的ASD患者（平均年龄：63.0±8.9岁；4例男性，9例女性）。我们测量了术前和术后的脊柱参数，包括胸腰段后凸（TLK），并计算了它们的差值（Δ）。主动脉长度（AoL）通过自动测量从腹腔动脉分叉到肠系膜下动脉的中央管腔线来确定。该测量使用对比增强计算机断层扫描进行三维主动脉重建。我们比较了术前和术后的AoL及其差值（Δ）。该研究考察了脊柱参数变化与AoL变化之间的相关性。结果 术后，主动脉长度增加（ΔAoL：4.2±4.9mm）。TLK变化与AoL变化之间存在负相关（R = 0.45，p = 0.012，β = -0.21）。未发现与其他脊柱参数有显著相关性。结论 ASD患者脊柱矫正手术后腹主动脉可延长4.8%。腹主动脉的延长程度与脊柱排列矫正有关。
