Meterials and method: Prospective study, described 25 cases of TTTS prenatal diagnosis qualify under ultrasound. Postnatal check: birth weight and evaluate general placental anatomy. Results: 100% of the cases are correctly diagnosed monozygotic twins with ultrasound. 100% of the cases have difference in birth weight more than 20%. 62% of the donor twins have velamentous or marinal cord insertion.
