Twin ‘connection’ with NEC

June 21st, 2012 by Dr. Jae H. Kim (MD, PhD, FRCPC, FAAP)

The reason why we see so many twins with NEC reflect a couple of things.The most important is the link between preterm birth and twins. Having multiple births puts you at higher risk of delivering preterm. The second issues is that twins sometimes can share a blood supply between them leading to a serious problem called twin to twin transfusion syndrome. In this case both twins develop risk factors that can set them up for NEC because one twin is compromised because of too much volume while the other is disadvantaged with too little blood volume.

Preventing twin pregnancies is not easy and in fact we see more twinning occurring as a result of artificial reproductive technologies so I see the problem only getting worse before better.
