AB In  some  pregnancies,  the  placenta  may  develop  at  an  abnormal  location  or  may  extensively  invade  the  adjacent  myometrium.  Clinical  entities  include  placenta  previa,  in  which  trophoblastic  cells  implant  over  or  near  the  internal  cervical  os  (Fig.  27-1).  In  other  cases,  trophoblast  aggressively  burrows  into  the  myometrium.  Depending  on  the  invasion  depth,  placenta  accreta,  placenta  increta,  or  placenta  percreta  is  diagnosed  (Fig.  27-2).  The  term  placenta  accrete  syndromes  is  clinically  useful  to  summarize  these  three  types  and  is  used  here  and  throughout  the  text.  Another  interchangeable  phrase  also  often  used  is  morbidly  adherent  placenta  (Bailit,  2015;  Silver,  2015a).
