We present a case of severe aortic coarctation in a donor of twin-twin transfusion syndrome. Patients underwent two angioplasty procedures at age 7 and 47 days, weighing 900 and 1500 g, respectively. Umbilical artery approach was used in the first procedure, and femoral artery approach was used in t

INTRODUCTION: Not much is known on the definition, occurrence and characteristics of proximate umbilical cord insertions (PCI) in monochorionic (MC) placentas. The purpose of this study was to establish a reference range for the distance between cord insertions and to evaluate the prevalence and ang

Twin birth rates have increased dramatically over the past three decades, and twins currently account for 3% of all pregnancies. Twin pregnancies of any type are at risk for prematurity. In addition, monochorionic twin pregnancies (25-30% of all twin pregnancies) are predisposed to a specific set of

概念

胎盤の血行動態が双胎間で不均衡なことで胎児間で血流の不均衡が起こり、このために胎児機能不全をきたす病態である。
一絨毛膜双胎の15%で見られる。(多くはMD双胎(一絨毛膜二羊膜双胎, monochorionic diamnionic))

病態

一絨毛膜双胎の胎盤においてはそれぞれの胎児の血管に吻合が存在する。正常例では均衡を保っているが、病的な例ではこの均衡が崩れ一方の胎児の血液が他方の胎児に流れ込む。供血児より血液を受けた胎児では循環血液量が多くなり、高血圧、腎血流増加による多尿、羊水過多をきたす。また容量負荷によりうっ血性心不全を来たし、胎児水腫をきたす。供血児では循環血液量が減少し、低血圧となり、腎血流量の減少により尿量の減少、羊水過少をきたす。また、循環血液量の減少により子宮内胎児発育遅延をきたす。羊水過多と羊水過少が進展すれば、供血児は子宮壁に押しつけられ成長が阻害される(stuck twin)。いずれの胎児でも胎児機能不全をきたす。
