This study defines normal growth for the various aortic segments in 128 spontaneously aborted human foetuses aged 15-34 weeks. With the use of anatomical dissection, digital-image analysis (using the Leica Q Win Pro 16 system) and statistical analysis (ANOVA, regression equation), a range of length measurements for the ascending aorta, aortic arch and thoracic aorta was examined. No significant gender differences were found (p > or = 0.05). The length of the ascending aorta ranged from 2.63 +/- 0.42 to 10.80 +/- 1.49 mm, according to the linear function y = -4.678 + 0.4647 x +/- 0.8447. The aortic arch length increased from 3.93 +/- 0.57 to 15.25 +/- 1.98 mm, in accordance with the linear model y = -6.079 + 0.6370 x +/- 1.1133. The length of the thoracic aorta ranged from 12.49 +/- 1.85 to 48.82 +/- 6.31 mm, according to the linear pattern y = -19.654 + 2.0512 x +/- 3.5168. The sum of the lengths of these aortic segments generated the linear function y = -30.410 + 3.153 x +/- 5.4332. The relationships between the lengths of the various aortic segments generated the linear regressions: y = -0.2256 + 0.7276 x +/- 0.3093 (for the ascending aorta vs. the aortic arch), y = 0.0252 + 0.3105 x +/- 0.2189 (for the aortic arch vs. the thoracic aorta), and y = -0.2408 + 0.22709 x +/- 0.2026 (for the ascending aorta vs. the thoracic aorta). The ascending aorta, aortic arch and thoracic aorta also increased proportionally (5:7:22) during gestation.
本研究确定了128例15至34周自然流产的人类胎儿各主动脉段的正常生长情况。通过解剖、数字图像分析（使用徕卡Q Win Pro 16系统）和统计分析（方差分析、回归方程），对升主动脉、主动脉弓和胸主动脉的一系列长度测量值进行了检查。未发现显著的性别差异（p≥0.05）。根据线性函数y = -4.678 + 0.4647x±0.8447，升主动脉长度范围为2.63±0.42至10.80±1.49毫米。根据线性模型y = -6.079 + 0.6370x±1.1133，主动脉弓长度从3.93±0.57增加到15.25±1.98毫米。根据线性模式y = -19.654 + 2.0512x±3.5168，胸主动脉长度范围为12.49±1.85至48.82±6.31毫米。这些主动脉段长度之和产生线性函数y = -30.410 + 3.153x±5.4332。各主动脉段长度之间的关系产生线性回归：y = -0.2256 + 0.7276x±0.3093（升主动脉与主动脉弓），y = 0.0252 + 0.3105x±0.2189（主动脉弓与胸主动脉），以及y = -0.2408 + 0.22709x±0.2026（升主动脉与胸主动脉）。在妊娠期间，升主动脉、主动脉弓和胸主动脉也成比例增加（5:7:22）。
