研究了在存在共同的解剖变异——前臂正中动脉的情况下长期趋势的发生。文献数据表明，在 1960 年之前研究的成人尸体中，正中动脉的发生率在 4.4% 至 8.3% 之间，而我们最近的研究发现，发生率高达 27.2%。采用统一方法对 224 具 1900 年至 1991 年出生的成人尸体和 60 具婴儿尸体进行研究，1900 年至 1910 年出生队列中正中动脉的发病率为 15.0%，1921 年至 1930 年上升至 29.7%，1951 年至 1960 年进一步上升至 38.1%，1951 年至 1960 年上升至 52.8%。 1980-1991。这一趋势具有统计显着性。由于大多数个体的正中动脉被认为在宫内生活的第 7 周左右就会逐渐缩小，因此将其保留到产后的个体比例不断增加可能表明人类宫内发育的最新趋势。 (C) 1995 Wiley-Liss, Inc.
Occurrence of a secular trend in the presence of a common anatomical variant-median artery of the forearm is studied. Data from the literature indicated the incidence of the median artery to be between 4.4 and 8.3% in adult cadavers studied before 1960 while our recent study found a frequency of 27.2%. In 224 adult and 60 infant cadavers of people born between 1900 and 1991 studied using a uniform method the incidence of the median artery in the birth cohort 1900-1910 was 15.0% of individuals, it rose to 29.7% in 1921-1930 and further to 38.1% in 1951-1960 to become 52.8% in 1980-1991. This trend is statistically significant. Since the median artery is deemed to dwindle away in most individuals around the 7th week of the intrauterine life, the increasing proportion of individuals who retain it into postnatal life may indicate a recent trend in human intrauterine development.
