  1. Ultrasound (TVUS), Ectopic Pregnancy

    show more
    Description: Many patients will not be as easy to diagnose and will require a transvaginal ultrasound (TVUS) exam, which requires an intracavitary ultrasound probe. This probe is of higher frequency, allowing greater resolution. By taking the intra-cavitary probe and inserting into the vagina with the indicator pointing to the ceiling one obtains a sagittal view of the uterus with an inferior approach (clip 5), as opposed to the transabdominal sagittal view, which provides an anterior approach. Once adequate images are obtained in the sagittal orientation, one may rotate the probe 90 degrees counterclockwise with the indicator to the patient’s right in order to obtain a coronal view of the uterus (clip 6) and attempt to locate the ovaries. Again, the identification of an extra-uterine mass in a pregnant woman is consistent with an ectopic pregnancy (clip 7). The presence of an extra-uterine gestational sac that contains a yolk sac or an embryo on TVUS has a sensitivity of 15-20% and a specificity of 100%.1,2 The presence of any noncystic extra-ovarian adnexal mass in a patient with a positive pregnancy test and no intra-uterine pregnancy (IUP) has a sensitivity of 84.4% and a specificity of 98.9%.1 The lack of an adnexal mass on ultrasound does not rule out an ectopic pregnancy. The presence of simple free fluid and the lack of an IUP in a pregnant patient may help, but it’s sensitivity and specificity is only 63% and 69%, respectively. 1. Brown DL, Doubilet PM.

  5. Ultrasound (TAUS), Ectopic Pregnancy

    show more
    Description: Conduct a transabdominal ultrasound (TAUS) exam by placing a low frequency convex or phased array probe over the midline suprapubic abdomen, superior to the mons pubis, with the indicator pointing cephalad (image 1) in order to obtain a sagittal view of the uterus. Correctly identify the uterus by first identifying its landmarks, the urinary bladder and vaginal stripe. The urinary bladder is located just superior to the pubic symphysis. Once the uterus is identified, use the probe to fan across the pelvis, to and from the right and left adnexa (clip 1). Once adequate images are obtained in the sagittal orientation, one may rotate the probe 90 degrees counterclockwise with the indicator to the patient’s right (image 3) in order to obtain a transverse view of the uterus (clip 2). Identify the ovaries, which are located lateral to the uterus and medial to the iliac vessels. Identification of the uterine cornua may aid in the localization of the ovaries. Ultrasound findings consistent with an ectopic pregnancy include visualization of an extra-uterine pregnancy (clips 2 & 3). Other findings suggestive of an ectopic pregnancy are the appearance of free fluid in the pouch of Douglas (clip 1) and the lack of an intra-uterine pregnancy.
