The use of high-frequency resolution ultrasound machines in the clinical practice and, particularly, high-frequency transvaginal probes, has permitted the study of the initial phases of the morphological development of the embryo and to detect possible pathologies. The diagnostic potential of TVS ultrasound is very high in the first weeks of embryonic development, but the operator needs a good knowledge of the processes of embryonic morphogenesis and the varying ultrasound findings that can be found in the first weeks of pregnancy. An ultrasound examination in the first trimester can also provide useful information in order to predict the risk of miscarriage. The elements on which such a prognosis is based are many. So I decided to clarify the above problems related to early pregnancy up to 14wks as:
- Guidelines for first Trimester pregnancy assessment: Minimum Standard for the first Trimester pregnancy.
- Implantation & its problems.
- Sonoembryology
- Biometry: importance of early GA establishment.
- Sonography of First Trimester pregnancy: normal & abnormal
- Pseudo pathology of Embryo
- Gestational Sac (GS) Amniotic cavity & extra embryonic celom.
- Yolk sac (YS)
- Anembryonic Pregnancy: Blighted Ovum.
- Chorionic frundosum & placenta; Bumps, Hydatid Mole / Gestational Trophoblastic Disease (GTD)- Sub chorionic Hematoma
- Incomplete Abortion & missed Abortion
- First trimester anomalies scan (FTAS)
- NT & Nasal bone (first trimester aneuploidy screening: FTS)
- Early foetal cardiac echo by TVS
- Ectopic pregnancy & pregnancy of unknown location(PUL): tubal, cervical, cs scar ectopic & other.
- Chorionic villous sampling: overview.
- Multifetal pregnancy: chronicity, early disparity & MFPR
