PARRA C, Mauro et al. COMPLICACIONES TARDÍAS DE LA TERAPIA LÁSER COMO TRATAMIENTO DE LA TRANSFUSIÓN FETO-FETAL: CASO CLÍNICO. Rev. chil. obstet. ginecol. [online]. 2011, vol.76, n.1, pp. 42-46. ISSN 0717-7526.  http://dx.doi.org/10.4067/S0717-75262011000100009.

We describe the diagnosis and management of twin anemia-polycythemia sequence (TAPS), which occurs as a late complication of successful laser therapy in twin monochorionic pregnancies developing severetwin to twin transfusion syndrome (TTTS). We offer a description of this late complication of laser therapy in this condition and a review of the related medical literature. Despite the successful introduction of laser therapy on the survival and neonatal sequelae, various early and late complications related to this procedure have been recently described. Among the late, stands out the death of one or both twins, recurrence of TTTS, and the appearance of TAPS. With regards TAPS, several authors have reported that it would be secondary to the presence, o persistence, of extremely small slow flow vascular communications, which lead to discre-pancies in the hemoglobin levéis between the twins, with no differences in blood volume.
