Soon after her admittance into ERCCF, a trans-rectal ultrasound was performed to determine two things. First, we want to measure the combined thickness of the uterus & placental unit.

An abnormal increase in its thickness is important to discover, for several reasons. First, it could be the result of an infection of the placenta that needs further diagnostic s performed followed by prompt medical treatment. Secondly, a foal could have difficulty breaking the thickened placenta during birth, which if unassisted, could lead to suffocation of the foal. An accurate and timely diagnosis will lead to early intervention and treatment resulting in a more positive outcome.
The second thing we want to determine by the trans-rectal ultrasound is the presentation of the foal. The foal should be oriented so that it will be born head first. The fetal orbit aids in documenting this proper positioning.

Foals born backwards are a cause of dystocia (difficult birth) and require immediate assistance for any hope of a live foal. These types of dystocias may result in a C-section.
