The full term human placenta is a flattened discoidal mass with an approximately circular or oval outline. However, variations can be present in the morphology in the form of bidiscoidal shape, lobed, diffused, fenestrated or circumvallate. The objective of the study was to find out the prevalence of morphological variations in placentas among deliveries in the Department of Obstetrics and Gynaecology in a tertiary care centre.
A descriptive cross-sectional study was conducted among total in the Department of Obstetrics and Gynaecology in a tertiary care centre after receiving ethical approval from the Institutional Review Committee (Reference number: 2308202105). The study was conducted between September 2021 to November 2021 and the shape of the placenta was observed and the variations present were noted. Point estimate and 95% Confidence Interval were calculated.
Out of 105 placentas observed, morphological variations were seen in two (1.91%) (0-4.53, 95% Confidence Interval). One (50%) was observed to be placenta succenturiata and one (50%) was triangular in shape.
The prevalence of morphological variations in placentas was found to be higher than the studies done in similar settings.
足月胎盘呈扁平盘状，轮廓大致为圆形或椭圆形。然而，胎盘的形态可能存在变化，表现为双盘状、分叶状、弥散状、有孔状或环状。本研究旨在探讨在三级保健中心的妇产科分娩中胎盘形态变异的流行情况。
在获得机构审查委员会的伦理批准（参考编号：2308202105）后，我们在三级保健中心的妇产科进行了一项描述性的横断面研究。该研究于 2021 年 9 月至 11 月进行，观察胎盘的形状并记录存在的变异。计算点估计值和 95%置信区间。
在观察的 105 个胎盘中有两个（1.91%）（0-4.53，95%置信区间）出现形态学变异。其中一个（50%）呈副胎盘，另一个（50%）呈三角形。
胎盘形态变异的流行率高于类似环境下的研究。
