Arterial vascularization of the vermiform appendix in human fetus

In 50 human fetuses of the crown-rump length ranging from 88 mm to 185 mm (12 to 20 weeks), the variability of the arterial vascularization of the vermiform appendix was investigated using the injection method. 3 vascularization types were distinguished on the basis of the size and number of the supplying arteries. The obtained results were compared with those reported by other authors who studied vermiform appendix vascularization in adults. In most cases the vermiform appendix is supplied by single ramus arising from ileocolic artery.
