Vanishing Twin Syndrome Symptoms
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. ...Read moreSee 1 more doctor answer
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 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. ...Read moreSee 1 more doctor answer
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. ...Read more

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. ...Read more

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. ...Read more

I have a fraternal twin brother with microdeletion 22q11.2 (velocardiofacial syndrome). What are the chances my children will have the same disorder?
Minimal: These odd micro-deletion syndromes are thought to arise as new defects which could be dominantly passed. Unless you carry it, you won't pass it to your kids and they would have the same risk as the general population to acquire it (new). You might benefit from discussing any and all genetic risk issues from both sides of the family with a geneticist. ...Read more
