Twin anemia?polycythemia sequence (TAPS) is an atypical form of twin?twin transfusion syndrome (TTTS) that presents as a large intertwin hemoglobin difference with one twin developing anemia and the other developing polycythemia, without oligohydramnios?polyhydramnios sequence (Lopriore et al., Placenta 2007;28:47?51). The prenatal diagnostic criteria for TAPS require that the middle cerebral artery-peak systolic velocity (MCA-PSV) measure greater than 1.5 multiples of median (MoM) in the donor twin and less than 0.8 MoM in the recipient twin (Robyr et al., Am J Obstet Gynecol 2006;194:796?803; Klaritsch et al., Ultrasound Obstet Gynecol 2009;34:149?154; Mari et al., N Engl Med 2000;342:9?14). The presumed etiology of TAPS involves the presence of small caliber arteriovenous anastomoses, which generate a slow transfusional process allowing for hemodynamic compensation (Lopriore et al., Placenta 2007;28:47?51; Lopriore et al., Placenta 2009;30:223?225; Lewi et al., Am J Obstet Gynecol 2006;194:790?795; Lopriore et al., Am J Obstet Gynecol 2008;112:753?758; Van den Wijngaard et al., Placenta 2007;28:611?615). The resulting polycythemia in the recipient twin is a risk factor for fetal and placental thrombosis (Van den Wijngaard et al., Am J Physiol 2005;288:R799?R814). We present a case of spontaneous TAPS complicated by a large placental vessel thrombosis and hydrops fetalis. Treatment via selective laser photocoagulation of communicating vessels (SLPCV) resulted in normalization of the MCA-PSV discordance.
