Venous Lake

Question: I had an ultrasound at 20 weeks, and it found a "prominent venous lake". What does this mean? My doctor wasn't sure, and had to ask the ultrasound doctor. This has me a little worried, as I have 3 children already, and have never heard of this before. I am 24 weeks pregnant now...

Answer: Not much to worry about...just a larger than average area of venous (vein) flow....it shows up on Ultrasound so the reading doc has to comment on it, but it's pretty much a nothing!

Question: what is a venous lake in your skull? Had an MRI they said everything was fine. I read my copy of the MRI it says that they found a small venous lake in my right skull base of the calvarium. Looked it up online could not find a thing. WTF is this? I never heard of it before, weas wondering if anyone else knew

Answer: in skull radiography, round to oval radiolucent foci in the frontal or parietal bones caused by dilated diploic venous channels.

Question: Does anyone know anything about Venous Lakes seen on Ultrasound? I am 34 weeks pregnant and have been told I need to have another ultrasound as the midwife saw "several Venous Lakes" in the placenta. I was told that there is a chance I could bleed out. Has anyone had any experience with Venous Lakes & do I have anything to worry about?

Answer: I see these from time to time. At each link, you can get more information: "Placental lakes are considered to be a normal finding in most cases." http://www.obfocus.com/questions/qanda37… This site says venous lakes are seen quite often: http://www.medical.philips.com/kr/produc… Occasionally, large and numerous venous lakes are seen when there is a placenta accreta. This means the placenta is abnormally firmly attached to the uterus. After delivery, it can be hard to stop the bleeding that occurs when the placenta separates from the uterine wall. BUT, a placenta can have venous lakes, and not have placenta accreta. "Three sonographic signs were found to predict placenta accreta: concomitant placenta previa; large or numerous placental venous "lakes"; and a remarkably thin, or even nonvisualized, lower uterine segment." http://findarticles.com/p/articles/mi_m0… Best wishes and try to relax. Your venous lakes are more than likely just a normal variant!

Question: what is placenta venous lake? ok, I'm 21 weeks pregnant and my ob discover a licking in the placenta she says that my baby is fine and not to worry, and she had me done another sonogram to see if the licking is worsen or is gone.......................but I wnat to know what this is and why it happen and if it has any affect to my baby or my pregnancy?

Answer: You should start asking your doctor these questions. Only they know you and your pregnancy well enough to explain it. You can try looking it up on Google.

Question: Has anyone ever had placenta previa AND placenta venous lakes? I've got a marginal previa and a lot of venous lakes. I'm 17 weeks and was wondering if anyone else has ever had both of these symptoms? I'm on bedrest and have been since 11 weeks. I'm already going crazy, and i'm afraid that i'll have to continue until my due date. I'll do anything for this baby, but I was seeing if there was anyone that had it go away..

Answer: I also had marginal placenta previa, but not the other. But by 36 wks the placenta moved up and out of the way and I was able to deliver naturally. So no worries YET...it may move on its own and may not thats what they told me. Hope all turns out ok for you. I know about the bedrest and yes it sucks. I was taken off bedrest after several weeks. But had to not be too active. Hope this helps you out some.

Question: Venous lakes seen on ultra sound in placenta? Please Help!? I am 34 weeks pregnant and have been told I have several Venous Lakes surrounding the placenta & that there is a chanc I may bleed out. Does anyone have any experience with Venous Lakes and do I have anything to worry about? Please help!

Answer: 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. Placental lakes are considered to be a normal finding in most cases. However, multiple placental lakes seen early in pregnancy in association with decreases 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.

Question: Succenturiate anterior lobe, posterior placenta with venous lakes, what does this mean for my baby? I was diagnosed at the ER at 15 weeks with succenturiate placenta and venous lakes, I was having some bleeding after falling out of the bed. I understand succ. is a twin placenta, but what are the risks for me during my c section, and does this indicate fetal abnormalities? I cant see my ob till jan8 and im a wreck. I've had 5 miscarriages (all hcg less than 298 considered blighted ovum) trying to have this baby. I cant really find any answers.

Answer: I just went through some scary stuff, so I'll try my best to help you out, although I don't have the answers!! succenturiate placenta: And a few develop in two quite separate pieces - a larger, roundish piece and a much smaller one, connected only by blood vessels running through the double layer of the membranes. The pieces may be several inches apart, and the smaller piece is called a 'succenturiate lobe'. Very occasionally, a placenta may have two or more succenturiate lobes. We have no idea why a succenturiate lobe may develop. Maybe a slight irregularity or tiny scar on the uterine wall makes a small area inhospitable to the growing placenta, forcing a lobe to 'move over' and grow elsewhere. But whatever the cause, from the baby's point of view, a succenturiate lobe makes little difference. Because the two parts of the placenta are connected by blood vessels, the organ works as a whole to nurture and protect the baby. There is no need for you to be especially careful with sporting activities (beyond the normal cautions advised during pregnancy) - or to avoid sex, unless you have been specifically advised to do so for other reasons. it is vital that all the pieces of the placenta are removed from the uterus at the end of labour. Failure to do so may result in haemorrhage and/or infection. As a matter of course, your midwife will examine your placenta closely after it is delivered. It should be obvious if any bits are missing, since there will be blood vessels leading off from the main placenta to a hole in the membranes. The remaining bit may then have to be manually removed from your uterus, generally under a spinal anaesthetic. Having said this, most odd-shaped placentae, including those with a succenturiate lobe, are delivered with no difficulty or delay. venous lakes: refers to the collections of blood flow between the placenta and inner wall of the uterus. Venous lakes alone are unlikely to cause problems to either yourself or the baby, but your obstetrician will be monitoring the placenta throughout your pregnancy to check for any further problems. Basically, neither should be of huge concern - your baby will be just fine! Continue to see your doctor on a regulaur basis for check-ups, especially near the end of your pregnancy. Best Wishes. Oh yes, If you have a posterior placenta, your placenta is on the back side of the womb and in back of your baby. It does not have any health implications, so it is not frequently something your healthcare provider will tell you unless you specifically ask. A posterior placenta is ideal for 3D/4D imaging.

Question: I need to ask questions about what's going on with my pregnancy right now.? Ok. I am 30 weeks pregnancy and have been admitted into the hospital for bleeding. I was told that I had a venous lake and was put on bed rest. The doctors have also told me that my heart rate is high ranging from 99-120. They think that is just natural for me though. I was dismissed from the hospital for two days and then went back again for bleeding. My water hasn't broken, but I am 1cm dilated with no effacement. The baby's head is still high. Last night, the baby's base heart rate was rather low for two hours, but now it is getting higher and back to normal. The doctors are unsure of why the baby's heart rate was king of low and are not exactly sure of what is causing the bleeding. They are keeping me for at least another day for evaluation. I recieved a steroid shot in my lower back for the baby's lungs before I fell asleep last night. The doctors keep mentioning that they are hoping not to have to induce labor when it is unneccesary adn they are just trying to sort things out... I head one of the nurses whispering to another about me behind my back, but I couldn't make out what she was saying. I am not sure what is going on. I am 18 years old and this is my first pregnancy and I don't want my baby being born ten weeks early.. I don't feel as if the doctor's are being straight with me and I need to know. Does it seem as if it could possibly be necessary to induce labor?

Answer: If your bleeding continues, and if your baby shows signs of distress (like a low heart rate that is alarming), then yes, you will need to deliver early, and it would most likely be via c-section if the baby is in severe distress or the bleeding is heavy. The good news is that at 28 weeks gestation newborn survival rates are over 95%, your baby would be fine at 30 weeks and would just need some extra time to grow in the hospital, to maintain it's body temp and blood sugar, to learn to feed and breathe at the same time, etc. 10 weeks sounds really early, but in the grand scheme of things it's not too bad, considering some women deliver extreme preemies at 23 weeks and they weigh less than a pound. You need to be assertive and ask your doctor and nurses more questions about what is going on. If you feel like they are "talking behind your back" you need to speak up and ask them what is being said. You are not a helpless passenger along for the ride. . . this is your body, your baby, and your care that you are in charge of, and they should be keeping you in the loop over everything happening.

Question: weird veins pattern on back of calf? i have this weird pattern on the back of one of my calfs. it doesn't look like spider veins, varicose veins, Telangiectasias, Venous Lakes, Reticular Veins, the pattern looks like tree branches with wide gaps between the veins (like 3/4 inch) and it's only from about 1 inch from above my ankle to the middle of the calf. it's a brown color and kind of looks like dirt but it's not. what is this? does it even have to do with veins? is it a skin condistion? oh i also forgot to say that it doesn't hurt and i've had it for a while now like +1.5 months

Answer: it could be a problem with your viens causing a different pignemtaion or vice versa. you may have hurt that area and that is you body's way of restoring it i recomend to go see a doctor A.S.A.P.

Question: physics: fluids at rest? 1. The venous blood pressure near the heart is usually about 0.7kPa. What is this pressure in a) inches of mercury? b) inches of water? c) pounds per square inch (psi)? 2. An object of density Po is released from rest below the surface of a fluid w/ density pf. The object may rise, sink, or remain at rest. Show that the object sinks if Po < pf, and will remain at rest if Po = pf. 3. If an ice cube melts in a glass of water, does the water level go down, up, or stay the same? Explain. 4. A tree trunk (density= 0.700g/cm3) is floating, partially submerged, in a lake. What percentage of the tree is underwater?

Answer: 1. a) 0.206 710 inches Hg. b) 2.813 053 inches water. c) 0.101 526 psi. 2. Buoyancy on object equals the weight of displaced fluid. Volume of displaced fluid = volume of object. Mass of displaced fluid = ρf V. Mass of object = ρo V. Buoyancy = weight of displaced fluid = ρf Vg. Weight of object = ρo Vg. Net force on object = bouyancy − weight = (ρf − ρo) Vg. Net force will be positive (forcing the object to float) if ρf > ρo; negative (forcing object to sink) if ρf < ρo; or null, if ρf = ρo. In this last case, object will not move by itself. 3. Ice floats because its density is 922 kg/m³, somewhat lower than that of water (1 000 kg/m³). 1 000 kg of ice occupy V = m / ρ = 1 000 / 922 = 1.085 m³. Now, 1 000 kg (of anything) weighs 9 800 N. To be in equilibrium, ice displaces 1 m³ of water, weighing 9 800 N. Thus, volume of ice over flotation line is 0.085 m³, or 85 lts. When the 1 000 kg of ice melt down, they occupy 1 m³, just the same space they displaced when solid. Conclusion: water level will remain the same. 4. Density of water × volume of displaced water × acc. of gravity = Weight of tree (in order to attain equilibrium). Density of water × vol. of displaced water = mass of tree . 1.000 × vol. of submerged portion of tree = 0.700 × vol. of tree. vol. of submerged portion of tree / vol. of tree = 0.700 = 70 %.

Question: physics: fluids? 1. The venous blood pressure near the heart is usually about 0.7kPa. What is this pressure in a) inches of mercury? b) inches of water? c) pounds per square inch (psi)? 2. An object of density Po is released from rest below the surface of a fluid w/ density pf. The object may rise, sink, or remain at rest. Show that the object sinks if Po < pf, and will remain at rest if Po = pf. 3. If an ice cube melts in a glass of water, does the water level go down, up, or stay the same? Explain. 4. A tree trunk (density= 0.700g/cm3) is floating, partially submerged, in a lake. What percentage of the tree is underwater?

Answer: 1. a. 1kPa = 0.29529988884912184 Inc Merc 0.7kPa = 0.20670992219438527Inc Merc b. 1kPa = 4.014630759755623 Inc H2O 0.7kPa = 2.810241531828936 Inc H2O c. 1kPa = 0.1450377438972831psi 0.7kPa = 0.10152642072809817psi 2. the force pulling it down is F = mg while m = vol * Po, the floating force is vol * Pf * g so the total force down on the object is: m * vol * (Po -Pf) (this assume the volume doesn't change) so if Po = Pf the forces cancel each other and the object will stay at rest if Po > Pf the object will sink (opposite to the question, but still ice is floating on water). 3. the water level will not change, since the ice floated. lets assume the mass of the ice is x if we will remove it the level of water will go down in x / Pw (density of water) the level change is related to mass of ice and density of water, no connection to the density of ice, so if we will return the ice in water formation now the water level will raise in x / Pw exactly. 4. let assume volume of tree is 1 cm^3, water density is 1 g/cm^3 the weight of tree is 0.7g the force of floating is vol * 1g/cm^3 = 0.7g, so vol = 0.7cm^3 so 70% of tree are underwater 3.
