The monoamniotic twin: a riskful event

The monoamniotic twin is at risk for high perinatal mortality because of co rd accidents. There is no consensus in literature for the obstetric managem ent in these cases. Contradictory results are reported according to fatal c omplications by cord accidents after 32 weeks gestation and safety of vagin al delivery. Recently two patients were admitted to our hospital with monoamniotic twin pregnancies and a fetal death in the third trimester. On the basis of these cases a review of the literature is presented and a case registry is recom mended. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
