Gestational sac measurement chart.

Fetal Pole. A fetal pole is an embryo, one of the first stages of pregnancy. In a healthy pregnancy, the fetal pole develops into a fetus. An early prenatal ultrasound can view and measure the fetal pole.

A mean gestational sac diameter cutoff of 21 mm (without an embryo and with or without a yolk sac) on the first ultrasound examination was required to achieve 100% specificity for early pregnancy loss.Volume-based measurements provided spurious results because of the irregular shape of most hematomas. Conclusions: Subjective hematoma size based on the fraction of gestational sac size correlates best with first-trimester pregnancy outcome. The earlier in pregnancy an SCH is detected, the higher the rate of subsequent pregnancy failure.Quantification. In early pregnancy, a subchorionic hemorrhage is considered small if it is <20% of the size of the sac, medium-sized if it is 20-50% 9, and large if it is >50-66% of the size of the gestational sac 5. Large hematomas by size (>30-50%) and volume (>50 mL) worsen the patient's prognosis 9.

The yolk sac is inside the gestational sac, a large cavity of fluid inside the uterus that surrounds an embryo. The yolk sac attaches to the outside of the developing embryo. The yolk sac must be inside the gestational sac, and the gestational sac must be inside the uterus. Otherwise, this can indicate the pregnancy has failed or will fail.
