What is vanishing twin syndrome?

Demise of one fetus: Vanishing twin syndrome is the demise of one twin sometime during the pregnancy. One study suggested it occurred about 20-30% of twin pregnancies. Most commonly it occurs early in the pregnancy and generally the remaining fetus has a good outcome. Its' occurrence later in pregnancy can be associated with adverse maternal and fetal outcomes.

Vanishing Twin Syndrome (Definition)

Vanishing twin syndrome is a condition where one fetus dies within the uterus and is partially or completely reabsorbed ...Read more

What are the tests for vanishing twin syndrome?

None.: Vanishing twin syndrome is probably much more common that people think; it results in a singleton pregnancy and current evidence suggests it is rather the norm than the exception. No test can predict this, only serial prenatal sonograms can document it.

Vanishing twin syndrome lost at 7 weeks. What is the likelihood that remaining twin will have something wrong with it?

Vanishing twin syndrome lost at 7 weeks. What is the likelihood that remaining twin will have something wrong with it?

Pretty small: The chances of a genetic defect in the remaining twin is very small as long as it continues to develop. On most occasions the surviving twin got the majority of the placental perfusion and that is why it is still present and hopefully growing.

Vanishing twin syndrome (lost at 5+ weeks), what is the likelihood of the remaining twin having something wrong with it?

Vanishing twin syndrome (lost at 5+ weeks), what is the likelihood of the remaining twin having something wrong with it?

Increased risk LBW: Compared to singletons, the surviving twin of VTS is at slightly greater risk of premature delivery, low birth weight and, for twin loss after 8 weeks gestation there is an increased risk for cerebral palsy. Loss of a twin at five weeks greatly reduces the risk for the surviving twin to have any adverse consequences.

Eggs splice, or the two fraternal twins suffer from vanishing twin syndrome and the twin literally absorbs the other twin, what does this mean?

Eggs splice, or the two fraternal twins suffer from vanishing twin syndrome and the twin literally absorbs the other twin, what does this mean?

Conjoined placenta: Unfortunately, the placenta often becomes shared between the twins and the one with the better access to the cotyledons of the placenta thrives and the other twin does not. An alternate scenario is when the two fraternal fetal twins are joined together but one does not develop as well as the other prior to placental development in the first trimester.

None.: Vanishing twin syndrome is probably much more common that people think; it results in a singleton pregnancy and current evidence suggests it is rather the norm than the exception. No test can predict this, only serial prenatal sonograms can document it. No specific therapeutic intervention is warranted.

I'm 39 & 6 weeks preg. W/ twins. How concerned should I be about vanishing twin syndrome? What should I expect at my visit in 2 weeks. I'm really scared

I'm 39 & 6 weeks preg. W/ twins. How concerned should I be about vanishing twin syndrome? What should I expect at my visit in 2 weeks. I'm really scared

Worrying will not: Help the matter any. Vanishing of one of the twin is being recognized more often due to the common use of ultrasound in early pregnancy. I understand your being concerned, but that will not affect the outcome. Please see this site for information on this topic. Http://emedicine. Medscape. Com/article/271818-overview.

I had slight bleeding but no pain or clots. Was told it was miscarriage could it be possible vanishing twin syndrome?

I had slight bleeding but no pain or clots. Was told it was miscarriage could it be possible vanishing twin syndrome?

Probably not: However, you could ask your doctor to check your serum HCG levels if you wanted to rule this out.

Will a vanishing twin (lost at 7 weeks) affect the results of first trimester Down's syndrome blood testing?

Will a vanishing twin (lost at 7 weeks) affect the results of first trimester Down's syndrome blood testing?

Unlikely: These tests rely on the active production of various markers in the blood and so a demised twin this early on will be unlikely to affect the test. These tests however, should be interpreted in the setting of a screening ultrasound to help better understand the risk. That being said, no test is ever 100% accurate, though they are useful. Consultation with a genetic counselor will help.

Will a vanishing twin (lost at 7 weeks) affect first trimester downs syndrome testing with blood test and ultrasound?

Will a vanishing twin (lost at 7 weeks) affect first trimester downs syndrome testing with blood test and ultrasound?

Vanishing twin: No, it would not affect your test result. Ultrasound would show it for a while, but the developing twin will eventually grow big enough to hide it from view.

Is it possible identical twins can have the same gender of a child? What's the possibility?

Is it possible identical twins can have the same gender of a child? What's the possibility?

If you are asking: If two identical twins, say both are women giving birth at the same time, have a higher chance of having the same gender for their babies, then the answer is no. The probability is 50% for 1 twin mother and 50% for the other twin mother delivering both a boy, 0.5 x 0.5 = 0.25 or 25%, but adding to the same probability for a girl. So 25% both girls + 25% both boys = 50%.

What is twin-twin transfusion syndrome?

What is twin-twin transfusion syndrome?

AKA TTTS: Ttts is when twins share abnormal blood vessel connections allowing one baby to "steal" blood from the other. Another name for this syndrome is poly/oli twins because one will have too much amniotic fluid (polyhydramnios) and the other too little fluid (oligohydramnios.) this is a high risk situation that will need to be carefully monitored by serial ultrasound and may require early delivery.

What is hidden twin syndrome? I was a hidden twin

What is hidden twin syndrome? I was a hidden twin

Hidden Twin Syndrome: Before ultrasound imaging of pregnancy, a twin pregnancy was sometimes missed, and not realized until the twin is delivered at birth. Now with ultrasound imaging, a twin is seen during examination. There is no dangerous hidden twin syndrome to worry you. Relax aabout this.

Is it possible for one twin to have Marfan syndrome and the other twin not have Marfan syndrome at all?

Is it possible for one twin to have Marfan syndrome and the other twin not have Marfan syndrome at all?

Yes: Since most twins are fraternal, they do not have the same genetic makeup & gene specific conditions can affect only one twin.
