[The position of the aortic bifurcation in humans].
We followed the position of aorta bifurcation in the arteriograms of 253 persons of known sex and age and in four human foetus. There exists a statistically relevant difference between sex and age. Bifurcation has a higher position in women than in men. In foetus the bifurcation position is placed relatively high--in the 3rd lumbal vertebra--in adults the bifurcation position is in the 4th lumbal vertebra. We can observe a slow decrease of aortal bifurcation to the distal direction in humans after 50 years of age. This descent is statistically significant.
