Combined Utero-Placental Thickness.
Measurement of the combined utero-placental thickness in a mid-gestation mare. The bladder is seen on the right hand side of the image, the fetal fluids on the left. A large vessel that runs along the cranioventral surface of the uterus is used to delineate the ventral edge of the uterus, and separate it from the wall of the bladder. Three measurements of the CTUP are taken. Note that the amnion seen within the fetal fluids is not included in the measurement. This technique can be useful in the diagnosis and evaluation of mares with ascending placentitis.
