AB Five  to  10  percent  of  women  have  vaginal  bleeding  in  late  pregnancy.  The  clinician  must  distinguish  between  placental  causes  (placenta  previa,  placental  abruption,  vasa  previa)  and  nonplacental  causes  (labor,  infection,  disorders  of  the  lower  genital  tract,  systemic  disease)  (eFigures  19–8  and  19–9).  The  approach  to  bleeding  in  late  pregnancy  depends  on  the  underlying  cause,  the  gestational  age  at  presentation,  the  degree  of  blood  loss,  and  the  overall  status  of  the  mother  and  her  fetus.  The  cause  of  antepartum  bleeding  after  midpregnancy  is  unknown  in  one-third  of  cases.
