Discordant CRL in monochorionic twins is associated with an increased risk of subsequent development of selective fetal growth restriction sFGR.

In the case of fetal demise of one fetus, there is a significant risk of ischemic brain damage in the surviving co-twin. A Fetal Medicine referral is needed.

OUTLINE/SCOPE. • Dating of the pregnancy (determining gestational age) the first-trimester scan in twin pregnancy is paramount. (EVIDENCE LEVEL: 4).

First trimester scanning is useful to identify abnormalities in the early development of a pregnancy, including miscarriage and ectopic pregnancy, and provides the most accurate dating of a pregnancy. Technique First trimester scanning can be performed using either an abdominal approach or a vaginal approach. Abdominal scanning is performed with a full maternal bladder, provides a wider field of view, and provides the greatest depth of view.

Vaginal scanning is best performed with the bladder empty, gives a much greater resolution with greater crispness of fine detail. In circumstances where both approaches are readily available, the greater detail provided by transvaginal scans usually outweighs other considerations, and is preferred. The patient is scanned in the normal examination position dorsal lithotomy with her feet secure in stirrups and her perineum even with the end of the examination table.

Place a small amount of ultrasonic coupling gel on the tip of the transvaginal transducer.

On the morning of finding out I was pregnant with our second baby, my husband Ben and I were ecstatic. Ben began making us scrambled eggs for brekky – life goes on with a toddler! When he calls me over and shows me that he had cracked a double yolker egg. Over the next few weeks I had 6 more eggs cracked in my presence that resulted in double yolkers. This even to me sounds unbelievable but I swear on everything I own and dearly love that it is the absolute truth.

Some often encountered skepticism, while others more frequently cared for women who were on the opposite end of the spectrum: getting far more ultrasounds than they needed at new standalone clinics that offer 3D and 4D scans. All of them suggested the deviations from recommended scans were a new cause for concern.
