Abstract:
Deep arteriovenous placental anastomoses in monochorionic placentas have been considered an essential etiological factor in twin-twin transfusion syndrome (TTTS). Moreover, some investigators have suggested that superficial anastomoses have a protective role. We report on confirmed cases of TTTS with only superficial anastomoses.
