Twin anemia-polycythemia sequence (TAPS) is a rare variant of twin-twin transfusion syndrome (TTTS) without the characteristic twin oligohydramnios-polyhydramnios sequence and cardiovascular milieu attributed to renin-angiotensin system mediators. It can occur spontaneously or iatrogenically after fetoscopic laser surgery. We report the case of a woman, gravida 2 para 1, with a monochorionic diamniotic pregnancy who developed Quintero Stage III TTTS. She underwent laser photocoagulation of identifiable anastornotic vessels and subsequently developed suspected TAPS 2 weeks later. The pregnancy was successfully treated with serial intrauterine intraperitoneal transfusions (IUT-PTs) of red blood cells. Although TAPS is a rare condition, serial middle cerebral artery peak systolic velocity measurements are warranted as follow-up in patients who have undergone fetoscopic laser surgery for TTTS. IUT-PTs may be superior to intravascular intrauterine transfusions in the treatment of this condition. Copyright (C) 2009 ISUOG. Published by John Wiley & Sons, Ltd.
