Placental lakes in first trimester

The image shows the placenta. During scans they can be seen as a black mass on the front wall of the womb above the baby.

All pregnant women were examined by two sonographic experts HSH and HSK.

Placental lakes in first trimester. First trimester placental lakes. Has anyone had experience finding plancental lakes in their first trimester. Mine were discovered at 102 due to bleeding.

Its 30 of my placenta and I had another scan yesterday 122 and it hasnt gotten worse but hasnt gotten better and Im being closely monitored. Wondering if anyone else has experienced this and what their outcome was. The pools of blood that lie on the placenta surface or sometimes inside the placenta are known as placental lakes and an ultrasound test can be used to locate these bleeds.

During scans they can be seen as a black mass on the front wall of the womb above the baby. Placental venous lakes refer to a phenomenon of formation of hypoechoic cystic spaces centrally within the placenta. Finding placental lakes during a second trimester ultrasound scan is not associated with any uteroplacental complication or with an adverse pregnancy outcome.

They can however be abnormal if very diffuse or if seen very early in pregnancy. Placental lakes can be seen within the placenta or on the fetal surface of the placenta bulging into the amniotic cavity. Slow swirling blood flow larger arrow may be seen within the spaces and the shape of the spaces tends to change with uterine contractions.

These features may help to distinguish a placental lakes from a thrombus. Placental lakes or intervillous spaces are usually hypoechoic with swirling echoes and demonstrate low-velocity laminar flow at B-mode or Doppler imaging. They are usually seen in the late second trimester or third trimester.

During the first trimester the cysts may be too small to identify at US and the echogenic mass may appear. The aim of our study was to establish whether there is a correlation between the size of placental lakes and adverse pregnancy outcome. Target ultrasonography for diagnosis of placental lake was performed in the 2nd trimester of pregnancy and followed up in the 3rd trimester.

Placental lakes were defined as homogenous sonolucent avillous lesions greater than 2 cm 2. Studies have shown women with thick placenta are more prone to develop placental lakes. Doctor pays more attention and keeps the check on the babys development in case of placental lakes in second trimester as it might cause reduction of average foetus size.

Lakes in the placenta are one of the best predictive signs in diagnosis of placenta accreta in the third trimester 16. Interestingly in the first trimester only three of our cases showed placental lakes. Case 5 was the only case with large placental lakes around the cord insertion site that became velamentous at the 20week scan.

Placental Lakes Another common ultrasound finding during pregnancy a lake or lacuna. This is common both during the first trimester and later in pregnancy. The incidence of these sonolucenies varies widely in studies from about 2 to over 17 in the 2nd and 3rd trimesters.

It is important to distinguish first trimester issues which could be more described as vesicular or multivesicular placenta than later during the pregnancy. According to the underlying etiology Doppler study may detect liquid movement within these lacunae but with no communication between them. The precise topography of placental lakes is important.

The women who have thicker placentas develop placental lakes more. Having placental lake is not too worry-some as it does not lead to any negative outcomes of pregnancy but can affect the baby size in case it gets detected in the second semester and this can be controlled as well if the doctor keeps a strict check on the growth of the baby ensuring it does not lag. The other risk worth noticing is that the spots or the placental lake.

ICD-10-CM Coding Rules. O43893 is applicable to maternity patients aged 12 - 55 years inclusive. O43893 is applicable to mothers in the third trimester of pregnancy which is defined as between equal to or greater than 28 weeks since the first day of the last menstrual period.

If a placental lake was present it was followed up by ultrasonography at every 4 weeks until delivery. All pregnant women were examined by two sonographic experts HSH and HSK. During ultrasonographic measurement umbilical and uterine artery Doppler velocimetry was also evaluated in women with placental lakes.

A finding of placental lakes was six times more likely with a thick placenta 3 cm at 20 weeks gestation OR 630 95 per cent CI 439 to 905. A finding of placental lakes during the second trimester ultrasound scan does not appear to be associated with uteroplacental complications or an adverse pregnancy outcome. Placental lakes are pools of blood that show up on scans as black areas.

They lie on the surface of the placenta or deeper inside. The image shows the placenta. The lakes are above the baby on the front wall of the womb uterus and can be seen as three small black areas on the surface of the placenta.

A recent study by Ballas et al. Suggests that sonographic findings in the first trimester included an irregular placental-myometrial interface anechoic placental areas low implantation of the gestational sac and placenta previa and may be detected early in gestation. In our case these features were visualized at 13 weeks and became more pronounced in the second trimester.

In the first trimester 0-13 weeks the surface of the chorionic villi is formed by the syncytiotrophoblast. These cells rest on a layer of cytotrophoblastic cells that in turn cover a core of vascular mesoderm. Therefore the placental barrier is relatively thick.

The surface area for exchange dramatically increases by full-term 27-40 weeks.
