胎盘作为母亲与胎儿之间营养及信息交流的中介,在维持胎儿宫内生长和发育等方面发挥重要的作用。正常的胎盘形态是胎盘维持自身功能的基础,受妊娠期营养状态、生活方式、妊娠并发症及宫腔操作史等诸多因素的影响。这些因素直接或间接地影响胎盘绒毛血管的生长,进而导致胎盘形态的改变,出现轮状、多叶等异常形态的胎盘。形态失常的胎盘运输营养物质的能力以及代谢等功能下降,从而在一定程度上影响胎儿生长发育,临床上常表现为胎儿生长受限、小于胎龄儿、胎儿窘迫、死胎甚至死产等诸多不良妊娠结局。因此,了解影响胎盘形态的因素及其机制,从多方面加以评估预防,可在一定程度上降低妊娠和胎儿不良结局的发生。
胎盤作為母親與胎兒之間營養及信息交流的中介,在維持胎兒宮內生長和髮育等方麵髮揮重要的作用。正常的胎盤形態是胎盤維持自身功能的基礎,受妊娠期營養狀態、生活方式、妊娠併髮癥及宮腔操作史等諸多因素的影響。這些因素直接或間接地影響胎盤絨毛血管的生長,進而導緻胎盤形態的改變,齣現輪狀、多葉等異常形態的胎盤。形態失常的胎盤運輸營養物質的能力以及代謝等功能下降,從而在一定程度上影響胎兒生長髮育,臨床上常錶現為胎兒生長受限、小于胎齡兒、胎兒窘迫、死胎甚至死產等諸多不良妊娠結跼。因此,瞭解影響胎盤形態的因素及其機製,從多方麵加以評估預防,可在一定程度上降低妊娠和胎兒不良結跼的髮生。

Placenta, serve as a mediation of nutrition and information exchange between mother and fetus, plays a vital role in maintaining the intrauterine growth and development of fetus. Placental function is based on its normal shape. Placental shape is often influenced by many factors, such as mother′s nutritional status, lifestyle, complications of pregnancy and operation history of uterine cavity. Those factors may directly or indirectly affect the growth of villous angiogenesis, leading to abnormally changes in placental shape, such as circumvallate and multi-lobate placenta. Abnormally shaped placenta has low efficiency in nutrients transporting and metabolism function, which to some extent, affects fetal growth and development with clinical manifestations including fetal intrauterine growth restriction, small for gestation age, fetal distress and even stillbirth, and other adverse pregnancy outcomes. Therefore, to understand those factors and their mechanisms that affect placental shape, and to evaluate and prevent those negative influence in many aspects, can reduce the adverse outcomes of pregnancy and fetal development to a certain extent.
