Other suggested mechanisms are vasospasm of the supplying arteries caused by humoral serotonin release or reflex uterorenal factors.

Other traumatic etiologies of abruption include separation of the placenta in a twin gestation after delivery of the first twin with subsequent decompression, attempted external cephalic version, and drainage of amniotic fluid associated with polyhydramnios in rare cases after amniocentesis for maturity studies.

Except for mild cramping, some patients may remain asymptomatic. If vaginal delivery is expected, which in some cases, depending on maternal and fetal status, may be the preferred route, the obstetrician should attempt an amniotomy as soon as possible, because it may benefit labor and also allows the placement of internal monitoring if desired.
