AB  - Abdominal  pain  and  vaginal  bleeding  are  common  complaints  of  patients  presenting  to  the  Emergency  Department  (ED)  in  the  first  20  weeks  of  pregnancy.  Ectopic  pregnancy  is  the  most  common  life-threatening  emergency  during  the  first  trimester  of  pregnancy.  The  current  incidence  of  ectopic  pregnancy  is  difficult  to  estimate  from  existing  data.1-3  The  overall  incidence  of  ectopic  pregnancy  has  increased  during  the  mid-twentieth  century  due  to  increased  occurrence  of  pelvic  inflammatory  disease.1-3  History  and  physical  examination  have  proven  to  be  unreliable  in  excluding  the  presence  of  an  ectopic  pregnancy.  Pelvic  ultrasound  (US)  is  the  diagnostic  test  of  choice  in  the  initial  evaluation  of  these  patients  with  possible  ectopic  pregnancy.
