True about ectopic pregnancy :
Correct Answer: All
Description: Ans. is a, b and c i.e. Transvaginal USG first imaging of choice; Associated with decidual reaction and In ectopic interstitial ring sign seen In ectopic pregnancy under the influence of estrogen, progesterone and chorionic gonadotrophin. there is varying amount of enlargement of the uterus with increased vascularity. Decidua develops all the characteristics of intra-uterine pregnancy except that it contains no evidence of chorionic This is k/a decidual reaction (i.e. option b is correct) Transvaginal USG (TVS) detects uterine gestational sac 1 week earlier than transabdominal probe (TAS), and gives a clear image because of its proximity to the pelvic organs. As discussed earlier not only it is the first imaging test which should be done but is also the imaging modality of choice (option a is correct). Color Doppler sonography can identify the placental shape (ring of fire pattern) and blood flow pattern outside the urine cavity. It is used to diagnose those cases of ectopic pregnancy which cannot be identified by TVS (i.e. option c is incorrect). USG findings in ectopic pregnnacy include demosntration of an extra uterine gestational sac appearing as fluid containing structure with an echogenic ring, "the tubal ring sign" (i.e. option d is correct: A single estimation of fihCG level either in serum or in urine confirms pregnacy but can not determine its location (i.e. option e is incorrect). When the (3hCG value is greater than 1500m1U/m1 and there is an empty uterine cavity, ectopic pergnancy is more likely. Failure to double the value by 48 hours along with an empty uterus is very much suggestive.
