Transverse Ventral Presentation.

Transverse Ventral Presentation.
A transverse ventral presentation is extremely rare due to the anatomical configuration of the bicornuate uterus of the cow. A transverse ventral presentation occurs with a Schistosomus reflexus fetal monster when the externalized fetal viscera are presented in the birth canal and the fetal limbs are directed anteriorly due to the extreme flexion of the vertebral column in the lumbar area.
