Sisters having twins and they only have 1 membrane?

Question

l got told yesterday by my sister that the doctors where she is scheduled to have her twins was very concerned as the identical twins inside her only have 1 membrane to share instead of two... have you heard of this before and what is the worse outcome???

her doctor has told her that she has a 50%-50% chance of either one of them surviving, she is getting really strassed and it's not good for her. They told her that if she can make it 4 more weeks then they can give her an early c section (she is 22 weeks).

the doctor said that she has a big chance of her twins getting that twin to twin tranfusion thing

Answer 1

I just found out that I am expecting twins. They are identical as well, monochroionic (one plactena) but mine are in seperate sacs. I was very worried about monoamniotic twins. It took FOREVER to find the membrane dividing them.

Twins having one sac, is very rare. Despite what some are saying on here. It is considered a high risk pregnancy. TTTS (twin-to-twin transfusion syndrome) is actually the least of her concerns. It can happen and will present a problem since they are in the same sac. (Treatment usually is removing the extra amniotic fluid from the recipient twin's sac.) But the biggest problem is cord entanglement. The survival rate of monoamniotic twins is 50%. Please don't think I'm telling you all this to scare you. I just wanted you to know the facts. She can have happy healthy babies.

When she delivers these babies, she will have to have a c-section. This is one of the few conditions that requires a c-section delivery.

I would recommend she get followed by a perinatologist that has experience with monoamniotic twins. She can delivery healthy babies. They will probably deliver her early because the farther she gets in the pregnancy the risk for death to one of the twins increases.

Although all this seems so unlucky, remind her that she is extremely lucky to be blessed with twins in the same sac. Because it is so rare. She is going to be blessed with the most unique and rarest form of twins there is. I wish you and your family the best of luck. I will keep you all in my thoughts and prayers.

Answer 2

Well, the fact that they have one membrane probably means that they share the chorionic sac. They are called monochorionic twins. Which means they are identical.

The concern would be if they were then also sharing the amniotic sac (monoamniotic twins). This occurs in only about 1-2% of all twins. The absolute worst that can happen is conjoining but this fortunately, is extremely rare.

I guess they want to make sure that both twins are getting what they need to grow and develop. There is a condition called Twin-Twin Transfusion Syndrome (TTTS) where the blood of one twin 'feeds' the other twin, one being called the 'donor' and the other the 'recipient'. The donor twin will not grow as well.

Fortunately, we have the advances of medicine at our aide and most babies are able to be cared for in utero. Congratulations on becoming Aunt to 2 little bundles of joy!!

Answer 3

You CAN have a normal pregnancy and delivery of normal twins with a monochorionic-monoamniotic gestation. However, your doctor will want to keep an eye on how they are growing.

One of the risks is something called "Twin-to-Twin Transfusion Syndrome", in which one twin gets more of the umbilical blood supply. This twin will grow at a faster rate than its sibling, while the other one will grow slower. It is possible, if this starts early enough in the pregnancy, that this will kill the smaller twin.

Another possible problem monochorionic twins face is cord entaglement. Both babies are sharing a single placenta and a single gestational sac. Because of this, there is a higher probability that one twin's cord will be compressed or looped around a neck.

These things don't happen all the time, though, so don't panic. Your sister is going to have a lot more ultrasounds than normal, just to make sure things go okay.

Answer 4

It depends on whether they mean one amniotic sac, or one placenta. "Membrane" to me sounds like the amniotic sac. If that's the case, it just means that when it ruptures, it will rupture around both babies. It's not uncommon at all, especially with identical twins. As there are lots of identical twins walking around perfectly healthy, it can't be TOO big an issue.

Answer 5

this shared placenta makes them identical twins since they were created by the splitting of one egg. fraternal twins have separate placentas as they developed from 2 eggs.
buy her the book, "What to Expect When You're Expecting".

Answer 6

whilst i grow to be pregnant with my third baby and that i grow to be around 37 weeks i had an ultrasound that stated there grow to be no fluid around my toddler and there for they had to set off me, you will in all probability be monitered interior the path of the being pregnant and in all probability precipitated in the previous than conventional if the fluid doesnt build up, i comprehend that in the event that they could have performed an ultrasound on me when I informed them some thing felt incorrect then i would not have had a dry delivery, and you deffinately dont choose a dry delivery, even inspite of the indisputable fact which you will in all probability have a cesar, it is likewise risky because it may develope right into a condition referred to as oligohydramnios and could lead directly to all sorts of issues, in case you pick extra information in this condition than google, stable luck, i wish each and every thing is going nicely for you and congradulations on concieving triplets needless to say

Answer 7

I've heard that's the highest-risk among twin pregnancies.
