Resumo: The disposition and ramification of the arteries and veins of the umbilical cord from cross-bred equine in different pregnancy stages were studied. Thirty fetuses, 18 male and 12 female with age varying from 73 to 249 days, were used and the umbilical vessels were injected with Neoprene latex 650 colored solution and further dissected. The length of the umbilical cord varied from 28 to 70 centimeters (mean of 47.5 centimeters). The umbilical cord included the urachus, two arteries and one umbilical vein. This latter presented, in average, 20.5 cm in length, and was constituted of two (86.66%) or three (13.33%) tributary veins. Arteriovenous anastomoses, funicular vessels besides the vasa vasorum were also observed. Arteriovenous anastomoses were found in 83.33% of the cases, varying from one to eight, and presented the following disposition: transversal (57.14%), convergent (9.52%), oblique (28.57%), "H"-shaped (2.38%), "V" transversal (1.19%) and "X" transversal (1.19%).

Utilizou-se para tal trinta fetos, 18 machos e 12 fêmeas com idade variando de 73 a 249 dias, em cujos vasos umbilicais foram injetados solução de látex Neoprene corada e posteriormente dissecados. O comprimento do funículo umbilical variou de 28 a 70 cm (média de 47,5 cm). O funículo umbilical inclui o úraco, duas artérias e uma veia umbilical. Esta última apresentava em média 20,5 cm de comprimento e estava constituida por duas (86,66%) ou três (13,33%) veias tributárias. Notaram-se, ainda, anastomoses arteriovenosas, vasos funiculares, além da vasa vasorum. Anastomoses foram encontradas em 83,33% dos casos, variando de uma a oito e com a seguinte disposição: transversais (57,14%), convergente (9,52%), oblíquas (28,57%), em "H" (2,38%), transversal em "V" (1,19%) e em "X" (1,19%).Universidade de São Paulo.
