The observations of the anatomical closure of the ductus venosus (DV) and vestige of DV were studied in 22 cattle, ranging from 210-day-old fetus to 3-years old Korean native cattle. Vinylite solution was injected into the hepatic, portal, umbilical veins and caudal vena cavae of 22 specimens for vinylite corrosion casts. The DV originated at the confluence of the umbilical and portal veins and emptied into the left hepatic vein or posterior vena cava. The DVs were persisted in a 210-day-old fetus, a 240-day-old fetus, and a 270-day-old fetus. Two newborns, two 2-year-old and two 3-year-old cattle had no rudimentum of DV (6 cases, 31.58%). However, vestiges of DV in varying sizes were observed in a 14-day-old, a 3O-day-old, two 180-day-old and nine adult cattle (13 cases, 68.42%). The lengths of vestiges of DV were about 4.97~99.66 mm. Therefore, the present study demonstrates that DV in cattle can be degenerated during the late period of a pregnancy.

The distribution of hepatic veins within the liver in 28 Korean native cattles were observed. Vinylite solution was injected into hepatic veins of seventeen specimens for cast preparation. The angiography was prepared in eleven specimens by injecting 30% barium sulfate solution into hepatic veins, and then radiographed on a X-ray apparatus (Shimadzu 800 MA 120 Kvp). 1. About two thirds or three quarters of the circumference of the Vena cava caudalis was embedded in the liver. The embedded portion was about 14~19cm in length. 2. The principal branches of the hepatic veins were Vena hepatica sinistra, Vena hepatica media, Vena hepatica dextra and Vena hepatica dorsolateralis; the three main hepatic veins were Vena hepatica sinistra, Vena hepatica media and Vena hepatica dextra. 3. The Vena hepatica sinistra joins the Vena cava caudal is near the esophageal impression of the liver. It gave off three or five branches to the left lobe. 4. The Vena hepatica media joined at the Vena cava caudalis close to the Vena hepatica sinistra. In all cases, Vena hepatica media opened near the diaphragmatic part of the liver than the Vena hepatica sinistra. It ran obliquely through the medial part of right lobe and quadrate lobe, giving off branches on each side. 5. The Vena hepatica dextra consisted of one(25 cases, 89.29%) or two separate veins(3 cases, 10.71%), joining to the Vena cava caudalis between the right and caudate lobes. 6. The flap of membranous tissue covered the dorsal half of the entrance of the Vena hepatica sinistra, media et dextra into the Vena cava caudalis. 7. The vestige of the ductus venosus persisted in the 12~18 months old cattles. 8. The anastomosis was observed in the intralobar and interlobar areas.

신생아 선천성 대사이상 선별검사에서 갈락토스혈증이 의심되는 경우, 혈관내피종과 같은 간 실질 내 종양을 동반할 수 있으므로 갈락토스혈증 관련 효소검사와 함께 간초음파 검사와 같은 영상학적 진단법, 총담즙산, AFP등의 측정을 병행하여야 원인감별에 도움이 된다. 저자들은 신생아 선천성 대사이상 질환 선별검사에서 갈락토스혈증이 의심되었던 생후 13일된 영아에 대하여 원인을 조사하던 중 복부초음파 검사에서 간 내 혈관내피종을 발견된 1례를 경험하였기에 이에 보고하는 바이다.
