Abstract

THE syndrome associated with intrauterine transfer of blood between uniovular twins has recently attracted clinical attention.^{1 2 3 4 5 6 7 8 9 10} As a consequence of blood transfer through anastomotic vessels in the of 2 additional pairs was also studied. Severe polyhydramnios often developed in the amniotic sac of the polycythemic twin. This led to premature delivery of at least 7 of the pairs (Table 1). Amniocentesis placenta 1 twin becomes polycythemic, and the other anemic. This feature resembles experimental parabiotic intoxication, but other features are unique because the parabiosis develops during intrauterine life. Polyhydramnios developing in the amniotic sac of the polycythemic twin often leads . . .
