Síndrome de transfusión intergemelar estadio iii, manejado con fotocoagulación láser guiada por fetoscopia, complicado con síndrome de ballantyne y rciu selectivo del feto donante: reporte de caso y revisión de la literatura

Objective: a 21 years old primigravid patient with biamniotic monochorial twin pregnancy and stage III twin-to-twin transfusion syndrome, diagnosed during week 23 of gestation is presented. She was managed with selective, sequential laser photocoagulation of the communicating blood vessels which was complicated by Ballantyne's syndrome (mirror syndrome) and selective intrauterine growth restriction (IUGR) of the donor fetus. She delivered during week 35 with good perinatal result. The object was to make an updated review of the literature about Ballantyne's syndrome. Materials and methods: the PubMed/ MEDLINE, Cochrane databases were searched as well as books on the specialization, related to the term "Ballantyne's syndrome" , with no restriction regarding publication date. Conclusion: selective, sequential la ser photocoagulation of the communicating blood vessels is the management of choice for twintwin fetus transfusion syndrome. Selective growth restriction of the donor fetus in stage III could be presented in 40% to 70% of cases. Ballant yne's syndrome could be secondar y to placental edema without fetal hydrops; suspecting it, helps to identify which patients could benefit from active management of this pathology.
