  17. Pseudosac Sac is thin. No double ring of decidua.

  18. Ectopic Pregnancy • defined as any gestation occurring outside the uterine cavity • 95% are tubal pregnancies, others involve ovary, cervix, or abdominal cavity

  19. Importance of Ectpoic Pregnancy • the incidence has doubled in past decade • causes 12% of maternal death in US • symptoms range from minimal to frank shock • high index of suspicion is required

  20. Clinical Presentations • should always be considered in the differential diagnosis of acute pelvic pain • classical triad may not be present : • Abdominal pain +/- referred pain at shoulder tip, • PV bleeding • Amenorrhoea

  21. Who are High Risk ? • previous ectopic pregnancy • current IUCD use • prior tubal surgeries • history of PID • prior infertility and the use of ovarian induction therapy

  22. USG findings of Ectopic Pregnancy • absence of Intrauterine sac • adnexal mass ± fetus • free fluid in cul-de-sac

  23. USG finding of definite Intrauterine Pregnancy • gestational sac with sonolucent center surrounded by thick, concentric, echogenic ring in the endometrium and containing a fetal pole, yolk sac or both
