Abstract
The extrahepatic blood vessels of the livers
one hundred and ninty nine Korean Fetuses aged
.~
from five to ten fetal months were observed anatornicaly.
1) The hepatic arteries were classified to three
types with ten subdivisions according to their origins.
The type I ; the celiac type was most numerous (84.
9%). the type IT; the mixed type which had two hepatic
branches. one originated from the celiac artery. the
other originated from the superior mesenteric or left
gastric artery. was the next order 02.6%), and the
type III; the hepatic artery had no origin from the
celiac artery. was few(2.5%).
2) Among the celiac type the text-book like type
was in 80.9%, and two cases of them were behind the
portal vein.
The cases of division of the proper hepatic artery
iito three branches. the left, right hepatic branches
and the gastroduodenal artery, were in 1.0%.
The cases that the left hepatic branch originated
from the proper hepatic artery were in 2.5%.
3) Among the 12.6% abnormal hepatic arteries. the
replaced left hepatic arteries from the left gastric
artery were in 2.5%. the replaced right hepatic arteries
f rom the superior mesenteric artery were in 4.0%, the
accessory left hepatic arteries from the left gastric
artery were in 1.5%, the accessory right hepatic arteries
from the superior mesenteric artery were in 3.0%.
Both left and right accessory hepatic arteries. the
replaced left hepatic artery with the accessory right
hepatic artery and the accessory left hepatic artery with
the replaced right hepatic artery were in 0.5% of each.
4) Among the five cases of the abnormal hepatic
arteries. the common trunk of the celiac with the superior
mesentery artery was in 0.5%, the right hepatic
artery originated from the abdominal aorta directly
was one case, the replaced left gastric artery from the
left gastric artery which originated from the abdominal
aorta directly was three cases(1.5%) .
5) The right hepatic arteries which crossed in front
of the hepatic duct were 11 cases (5.5%).
6) The single cystic artery was in 88.9%. the double
cystic arteries were in 11.1%.
7) The cases of 93.8% of the single cystic artery and
86.4% of the double cystic arteries originated from the
artery which distributed to the right hepatic lobe. Most
of them originated from the typical right hepatic artery
and a few from the superior mesenteric artery. proper
hepatic artery and the gastroduodenal artery.
8) Majority of the cystic artery originated in the
Calor's triangle and reached the gall bladder without
crossing the hepatic duct.
9) The union of the three radices of the portal vein
had three types.
The type I. union of the inferior mesenteric vein
with the lienal vein was most numerous(48.8%).
The type IT. union of the inferior mesenteric vein
with the superior mesenteric vein was next
(42.7%).
The type III. the inferior mesenteric vein join with
the angle between the two mesenteric veins. 'was
least (5.0%).
10) The development of the inferior mesenteric vein
was slow compared with the development of the other
two racidies.
The left and right branches of the portal vein were
larger than the trunk of the portal vein throughout
the fetal life.
11) The diameter of the Ductus venosus was less
than half of the diameter of the umbilical vein and
the development of the Ductus venosus was very slow.
Therefore a small amount of blood which comes
through the umbilical vein circulates through the
Ductus venosus.
