Abstract

Twin pregnancy is associated with an increased risk of perinatal and maternal complications, and early establishment of the chorionicity type defines this risk. In monochorionic (MC) pregnancies, the fetuses share the same placental mass and exhibit vascular anastomoses crossing the intertwin membrane, and the combination and pattern of anastomoses determine the primary clinical picture and occurrence of future complications. Twin Anemia-Polycythemia Sequence (TAPS) was first described in 2006 after fetoscopic laser surgery in twin-to-twin transfusion syndrome (TTTS) twins, and in 2007, the first spontaneous cases were reported, recognizing TAPS as an individualized vascular identity in fetofetal transfusion syndromes. There are two types of TAPS: spontaneous (3-5%) and iatrogenic or postlaser (2-16%). TAPS consists of small diameter arteriovenous anastomoses (<1 mm) and low-rate, small-caliber AA anastomoses in the absence of amniotic fluid discordances. There are certain antenatal and postnatal diagnostic criteria, which have progressively evolved over time. New, additional secondary markers have been proposed, and their reliability is being studied. The best screening protocol for TAPS in MC twins is still a matter of debate. This review provides a survey of the relevant literature on the epidemiology, vascular pathophysiology, underlying hemodynamic factors that regulate mismatched vascular connections, and diagnostic criteria of this condition. The aim is to increase awareness and knowledge about this recently identified and frequently unrecognized and misdiagnosed pathology.

双胞胎贫血-红细胞增多症序列(TAPS):从基础研究到临床实践。
双胎妊娠与围产期和产妇并发症的风险增加有关,绒毛膜性类型的早期确定确定了这种风险。在单绒毛膜(MC)妊娠中,胎儿共享相同的胎盘团块,并表现出穿过双胎膜的血管吻合,吻合的组合和模式决定了主要的临床表现和未来并发症的发生。2006年,双胎贫血-红细胞增多症序列(TAPS)首次在双胎输血综合征(TTTS)双胞胎的胎儿镜激光手术后被报道,2007年,第一例自发性病例被报道,认识到TAPS是胎儿输血综合征的个体化血管身份。tap有两种类型:自发性(3-5%)和医源性或激光后(2-16%)。TAPS由小直径动静脉吻合术(
