AB  - Following  fertilization  and  fallopian  tube  transit,  the  blastocyst  normally  implants  in  the  endometrial  lining  of  the  uterine  cavity.  Implantation  elsewhere  is  considered  ectopic  and  comprises  1  to  2  percent  of  all  first-trimester  pregnancies  in  the  United  States.  This  small  proportion  disparately  accounts  for  6  percent  of  all  pregnancy-related  deaths  (Berg,  2010;  Stulberg,  2013).  In  addition,  the  chance  for  a  subsequent  successful  pregnancy  is  reduced  after  an  ectopic  pregnancy.  Fortunately,  urine  and  serum  beta-human  chorionic  gonadotropin  (β-hCG)  assays  and  transvaginal  sonography  have  made  earlier  diagnosis  possible.  And  as  a  result,  both  maternal  survival  rates  and  conservation  of  reproductive  capacity  are  improved.
