a marginal or a complete previa during the second trimester
can be reevaluated later in gestation and scheduled for
caesarean section, as required. It is important to rescan
during the latter stages of development, as the placenta may
“migrate” (i.e. as the uterus grows, the discs are displaced
craniad). Diagnosis of this condition requires accurate
localization of the placenta in relation to the cervix on
longitudinal scans. It should be noted that a distended
urinary bladder may alter the relationship of the placenta to
the cervix, which can lead to misinterpretation. Animals
that display retroplacental or subchorionic hemorrhage are
also closely monitored; if continued and considerable
hemorrhage is noted, emergency surgery is performed. Of
the nine concealed abruptions detected during three
breeding seasons (GD 51
e
125; 9/873 or 1%), no maternal
deaths occurred. One interesting feature that has been
frequently associated with abruptions is the proliferation of
