Rezumat: The vanishing twin syndrome is part of the much more complex notion of death of a foetus in utero, but it expressly refers to the succumbing and disappearance of one or more embryos of foeti, in the environment of a multiple pregnancy, during the first trimester of pregnancy. The embryo-foetal disappearance can be due to some genetic causes, anatomic anomalies, placenta insufficiency, infections or related maternal pathological situations such as high blood pressure and diabetes. The article proposes the presentation of this particular situation of the multi-foetal pregnancy, in terms of the diagnostic, the conduct and the obstetrical prognostic, presenting the experience of its own cases and the existing data in the specialty literature. Cuvinte cheie: multiple pregnancy, first trimester, vanishing twin.
