title: [Twin-twin transfusion syndrome and intraventricular hemorrhage followed by hydrocephalus: report of two cases].
abstract: We report 2 infants who were born as one of monochorial twins. Both of them had been suffering from twin-twin transfusion syndrome(TTTS) as a donor fetus. Case 1 was delivered by caesarean section at the 28th week of pregnancy. On day 0, intraventricular hemorrhage(IVH) occurred from the right subependymal germinal matrix layer, and progressive ventricular enlargement was followed. Case 2 was delivered by the caesarean section at the 31st week of pregnancy. On day 9, he developed IVH from the choroid plexus at the trigone of the left lateral ventricle, and progressive enlargement of the inferior and posterior horns, trigone and posterior part of the body of the left lateral ventricle was followed. IVH in patients with TTTS usually occur in recipient infant but it can also occur in donor infant as in our cases. Pathophysiology of central nervous system damages associated with TTTS is variable and complicated.
