Transabdominal ultrasonography – Ultrasound is performed across the abdominal wall or through the abdominal cavity; In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity. Fortunately, gestational sac, yolk sac and embryo are surrounded by hyperechoic (brighter) body tissues.
The mean sac diameter [3] can effectively estimate the gestational age [4] between 5 and 6 weeks, with an accuracy of about +/- 5 days. [5] The yolk sac and embryo should be readily identifiable when the gestational sac reaches a certain size — a yolk sac should be seen when the gestational sac is 20mm and a fetal pole should be seen when the ...
With obstetric ultrasonography the gestational sac (intrauterine fluid collection) can be visualized at 4.5 to 5 weeks gestation, the yolk sac at 5 to 6 weeks gestation, and fetal pole at 5.5 to 6 weeks gestation. Ultrasound is used to diagnose multiple gestation, which cannot be diagnosed based on the presence of hCG in urine or blood. [15]
The yolk sac is the first element seen within the gestational sac during pregnancy, [1] usually at three days gestation. The yolk sac is situated on the front part of the embryo; it is lined by extra-embryonic endoderm, [3] outside of which is a layer of extra-embryonic mesenchyme, derived from the epiblast.
In the human embryo, the vitelline duct, also known as the vitellointestinal duct, [1] the yolk stalk, [1] the omphaloenteric duct, [1] or the omphalomesenteric duct, [1] is a long narrow tube that joins the yolk sac to the midgut lumen of the developing fetus. [2]
Absence of embryo with heartbeat 7–10 days after a scan that showed a gestational sac with a yolk sac. [110] [111] Absence of embryo at least 6 weeks after last menstrual period. [110] [111] Amniotic sac seen adjacent to yolk sac, and with no visible embryo. [110] [111] Yolk sac of more than 7 mm. [110] [111]
Transvaginal ultrasonography showing a gestational sac with a diameter of 28 mm, corresponding to a gestational age of approximately 7 weeks and 5 days. It contains a yolk sac (protruding from its lower part) but no embryo, even after scanning across all planes of the gestational sac, thus being diagnostic of an anembryonic gestation. Specialty ...
