人类第四和第五腰动脉的解剖结构：对一百名活体受试者的动脉造影研究。

本文报道了100例活体腰椎椎体前外侧动脉的解剖结构。这种解剖学的经典描述在年轻受试者中通常是正确的。此外，在7名10岁或以下受试者中的5名中观察到了肋前吻合。在老年受试者中观察到这种模式的扭曲;大多数这种扭曲是由于退行性疾病。在30岁以上的10岁年龄组中，观察到的第五腰椎椎体周围动脉的平均数量稳步下降，但在动脉造影的适应症类别之间，以及在被判定为严重动脉粥样硬化的患者和被动脉造影判定为非动脉粥样硬化的患者之间，均未发现统计学显著差异。在一些患有动脉疾病的老年患者中，肋前吻合是一种重要的侧支供应。此外，在15例受试者中观察到第四腰动脉的共同起源动脉，在2例受试者中观察到第四腰动脉起源于骶正中动脉。这些特征以前在健康受试者中没有描述过。
The anatomy of the arteries on the anterolateral surfaces of the lower two lumbar vertebral bodies has been described in 100 living subjects, using radiographs obtained at aortography. The classic description of this anatomy is commonly correct in the young subject. In addition, a precostal anastomosis was seen in 5 out of 7 subjects aged 10 years or younger. Distortion of this pattern was seen in older subjects; most of this distortion was due to degenerative disease. The average number of observed arteries around the fifth lumbar vertebral body declined steadily in decennial age groups over 30 years, but a statistically significant difference could not be found between the categories of indications for aortography, nor between those judged grossly atherosclerotic and those not so judged as a result of aortography. The precostal anastomosis is an important collateral supply in some older subjects with arterial disease. In addition, a common artery of origin for the fourth lumbar arteries was observed in 15 subjects, and an origin from the median sacral artery for the fourth lumbar arteries was observed in two subjects. These features have not previously been described in healthy subjects.
