Shouldn't it be called umbilical artery? dave 03:43, Apr 16, 2004 (UTC)

No, it's the umbilical vein. The terms vein and artery indicate direction of bloodflow to or away from the heart, respectively—they are not related to the oxygen content of the blood contained within the vessel. Thus, even though the vessel carries oxygenated blood, it's still called the umbilical vein because it's carrying the blood to the heart from the placenta. (FYI, vessels that carry deoxygenated blood back to the placenta are called the umbilical arteries.) --Diberri | Talk 06:18, Apr 16, 2004 (UTC)

Dicrepancy here in whether the umbilical vein is obliterated within a week but can be used for venous catheterisation for several weeks after birth. ??

Recanalization of the umbilical vein is a myth??

This study in 1985 disproves it, but the factoid seems to have persisted. http://www.ncbi.nlm.nih.gov/pubmed/3881894 —Preceding unsigned comment added by 188.221.113.56 (talk) 18:49, 1 December 2010 (UTC)[reply]
