Abstract

The author studied 131 Korean infant (male 44, female 87) and 30 adult (male.-a, female 7) cases in - respect to pattern of ramification of the internal iliac artery and. to the size of caliber of its. main. branches,: and obtained the following -conclusion.
1. In 63.0% of the cases the -iliac and--the-lumbar branches of the iliolumbar artery arise in a common stem and in 37.0% each of them-originates independently.
The iliolumbar artery originates from the internal iliac artery in 66.9%, from the superior -gluteal artery in 26.9%, and from the common iliac artery in 6.2%.
2. The lateral sacral -artery is observed in 58. 8% to consist -of two, in 32.0% to consist of one and in 9.2% to-Consist of three in number. In 88.3% it arises from the superior gluteal artery.
3. The obturator artery originates - in 15..5% either from the external ?iliac artery or from the inferior epigastric artery (so-called Corona Mortis), in 31.4% from the internal iliac artery and in 23.3%- from the superior- gluteal artery.
4. The pattern of ramification of the superior gluteal, the inferior gluteal; - internal pudendal and the umbilical artery is observed as type I in 49. 7%, type III in .29. 2%, type ,II -in 9. 9%, type V-in 5.6% and type IV in 4.7%.
5. In the infant very little increase is measured in the size of caliber of the internal iliac artery, the superior gluteal, the inferior gluteal and the internal pudendal; on the contrary a little decrease is rather measured in the size of caliber of the umbilical artery. There is no difference as to sex and between the right and the left in the size of caliber of them.
6. In infants the mean of the caliber of the internal iliac artery shows 2. 0 mm and in adults the mean figures 4.5mm.
7. The mean caliber of the superior gluteal artery shows 1. 1 mm in infants and 3.1 mm in adult.
8. The mean caliber of the inferior gluteal artery reveals 1. 1 mm in infants and 2. 8 mm in adult.
9. The mean caliber of the internal pudendal artery figures 0. 9 mm in infants and 1. 8 mm in adult.
10. The mean caliber of the umbilical artery shows 0. 9 mm in infants and. rather decreases to 0. 8 mm in adult.
