They may also be familiar with criteria that at 16 or 20 mm mean sac diameter (MSD) a fetal pole should be seen.
The USG criteria used for diagnosis of early pregnancy failure (missed abortion) were-embryo greater than 7 mm with no embryonic cardiac activity or irregular gestational sac with mean sac diameter greater than 16 mm or a gestational sac more than 15 mm with no visible fetal pole.
Gestational age was estimated standard measurement of mean sac diameter of Gestational sac, Crown rump length of embryo.
A missed abortion is further distinguished sonographically as either an "anembryonic pregnancy"--a mean sac diameter of >10 mm and no yolk sac or a mean sac diameter of 20 mm and no embryo on transvaginal ultrasound--or as an "embryonic demise"--a crown rump length of [greater than or equal to]6 mm without cardiac activity on transvaginal ultrasound.
In addition, the sensitivity for diagnosis of an intrauterine pregnancy increases when the HCG levels are greater than or equal to 2,000 mIU/mL or the mean sac diameter is greater than or equal to 3 mm, Gloria Chiang reported at the annual meeting of the American Institute of Ultrasound in Medicine.
Revised criteria for the diagnosis of pregnancy failure with endovaginal ultrasound * Crown-rump length [greater than or equal to] 7 mm without a heartbeat * Mean sac diameter of [greater than or equal to] 25 mm with absence of an embryo * Lack of an embryo [greater than or equal to] 2 weeks after a prior ultrasound demonstrated a gestational sac without a yolk sac * Lack of an embryo [greater than or equal to] 11 days after a prior ultrasound demonstrated a gestational sac with a yolk sac
Analysis was done using Coefficient correlation (r) between the various variables such as menstrual age v/s crown rump length and menstrual age v/s mean sac diameter.
The mean sac diameter increases by 1 mm/day in a normal pregnancy.
Certain threshold measurements of mean sac diameter (MSD):
Absence of a heartbeat when the CRL is in the 1- to 4-mm range is definitely worrisome, as is a [beta]HCG of more than 1,000 with no gestational sac, or a mean sac diameter of more than 16 mm with no heartbeat.
