AB  - An  ectopic  or  extrauterine  pregnancy  is  one  in  which  the  blastocyst  implants  anywhere  other  than  the  endometrial  lining  of  the  uterine  cavity.  As  such,  they  account  for  1  to  2  percent  of  reported  pregnancies  in  the  United  States  (Zane,  2002).  With  the  advent  of  a  sensitive  and  specific  radioimmunoassay  for  the  β-subunit  of  human  chorionic  gonadotropin  (β-hCG),  combined  with  high-resolution  transvaginal  sonography  (TVS),  the  initial  presentation  of  a  woman  with  an  ectopic  pregnancy  is  seldom  as  life  threatening  as  in  the  past.  Nevertheless,  ectopic  pregnancies  remain  an  important  cause  of  morbidity  and  mortality  in  the  first  trimester  of  pregnancy  in  the  United  States.
