co-twin

基本解释

This carries the risk of brain, renal, and cardiac damage – or even death – of the co-twin .
这将可能损害健康胎儿的大脑、肾脏和心脏，甚至导致死亡。
In a dichorionic pregnancy, if a co-twin weighs 320 g at 26 weeks and is at high risk of in utero death, we typically would advise the parents to delay delivery.
在双绒毛膜双胎妊娠中，如果其中一个胎儿在26周仅重320克，发生宫内死亡风险很高时，我们通常会建议推迟产妇的分娩时间。
Beyond 60, however, the odds of one twin reaching a given age are greatly increased if their co-twin has done so, especially if the twins are identical (Human Genetics, vol 119, p 1432).
然而，60岁之后，若双胞胎中的一个达到某一既定年龄则另一个达到这一年龄的可能性急剧增加，当双胞胎为同卵双胞胎时尤甚（人类遗传杂志Human Genetics vol 119 p 1432）。

There has been a failure to co-ordinate the twin enlargements.
