Prenatal Diagnosis of TRAP sequence: A Case REport -Usefulness of Color Doppler Sonography- / 대한주산의학회잡지

Twin reversed arterial perfusion (TRAP) sequence is a rare specific anomaly of twin gestation with fused placenta and umbilical anastomosis. This syndrome occurs once in about 34,600 births and reported first by Beneditti in 1533. We report on prenatal diagnosis of a case of TRAP sequence with color Doppler sonography, this case is presented with a brief review of the literature.

Acute Intermittent Porphyria and Pregnancy / 대한산부인과학회잡지

The Porphyria are a group of inherited and acquired disorders characterized by partial defects in the heme biosynthetic pathway. Among the hepatic forms, acute intermittent porphyria(AIP) is the most severe and common type in western hemisphere. Though its association with pregnancy is rare, it presents the obstetrician with challenging problems in diagnosis and management and it is probable that pregnancy had some deleterious effect in acute porphyria. The authors present a cae of AIP in pregnancy with a review of literature.

A Case of Acute Twin-Twin Transfusion Syndrome / 대한산부인과학회잡지

Twin-twin transfusion syndrome(TTTS) is a serious complication of monozygotic mu-ltiple pregnancy. TTTS is associated with high perinatal mortality rate. The acute form has been attributed to rapid transfer of blood through superficial artery-to-artery or vein-to- vein anastomoses during labor and delivery, resulting in a hypovolemic, anemic donor twin and a hypervolemic, plethoric recipient twin of similar birth weight. The authors present a case of acute twin-twin transfusion syndrome with a review of literature.
