“…The rate of TTTS in monochorionic triplet pregnancies is unknown (Sepulveda et al, 2005), while in monochorionic twin pregnancies the incidence is 15% (Sebire et al, 2000). Previous studies have demonstrated high rates of morbidity and mortality associated with TTTS in monochorionic triplet pregnancies (Adegbite et al, 2005;Enzetami et al, 1997;Fisk et al, 1990;Hayashi et al, 2005;Ishii et al, 2006;Leung et al, 2003;Ling et al, 2000;Pons et al, 1990;Rehan et al, 1995). Expectant management (Enzetami et al, 1997;Fisk et al, 1990;Pons et al, 1990), termination of pregnancy (Chasen et al, 2002;Diemert et al, 2010), amnioreduction (Adegbite et al, 2005;Chasen et al, 2002;Hayashi et al, 2005;Leung et al, 2003;Ling et al, 2000;Rehan et al, 1995), and laser photocoagulation (Chmait et al, 2009;Diemert et al, 2010;Ishii et al, 2006;Sepulveda et al, 2005;Van Shoubroeck et al, 2004) have been reported to treat these pregnancies.…”
