I had my ultrasound this morning and well I’m not really sure how to describe it. The baby itself looks good. Baby is growing right on track (actually measured a couple of days ahead at 15 weeks 3 days) The “spot”, the whole reason for this ultrasound, has grown. My ultrasound tech(s), as I had one in training and their supervisor, believe that it is a Venous Lake. Also what my OB was guessing but we were staying on the positive side with “its just a vain”. Before you go to google I’ve already done that for you. Although boring, a better explanation than I can do. Enter perinatology.com
Placental lakes are enlarged spaces in the placenta filled with maternal blood. These spaces are also called intervillous spaces because they are found between the placental villi the finger-like projections of the placenta that contain fetal blood vessels . The placental villi float in the intervillous spaces and absorb oxygen and nutrients from the maternal blood.
The blood-filled placental lakes appear nearly black on ultrasound because they do not reflect soundwaves back to the ultrasound machine. 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 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 are considered to be a normal finding in most cases. However, multiple placental lakes seen early in pregnancy in association with decreased umbilical artery
blood flow have been associated with fetal growth restriction. In a patient with placenta previa and previous uterine surgery multiple placental lakes should raise suspicion for placenta accreta or percreta. Multiple placental lakes may also mimic gestational trophoblastic disease.
Gosh, I do love Google. So I basically think that everything is going to be fine and that it is a normal finding right…? I really have no idea if I need to be concerned or not. The one thing that makes me a little worried is that mine is not small. It is quite large in fact. It was 8cm long 2 1/2 weeks ago, now it is over 9 1/2 cm long. (The tech turned the monitor so I had a hard time seeing, I have quite the name for her right now) which means the baby and the venous lake are about the same size. Again, NOT small. Ug. I know I’m freaking myself out but a “pocket” of blood the size of my baby can’t be a good thing. Just saying.
If you care to send some prayers, good thoughts, lucky ju-ju my way that would be great. But onto the fun stuff. I only got one photo today and it isn’t that great but I also have the 12 week ultrasound shots from my ER visit too.
