AIM
To investigate the association of cornual-fundal location of the placenta and breech presentation at term delivery.
METHODS
This study was conducted at the Department of Obstetrics and Gynecology, Novi Sad, in 2011. The inclusion criteria were delivery at ≥37 weeks of gestation, singleton gestation, and cornual-fundal location of the placenta determined by ultrasonography at ≥37 weeks of gestation when 3/4 or more of the placenta was in the cornual-fundal region.
RESULTS
Out of 2750 ultrasound examinations performed, 143 showed cornual-fundal location of the placenta (frequency 5.2%). Eighty six cases had cephalic presentation (60.14%) and 57 (39.86%) had breech presentation. Of the remaining cases with non- cornual-fundal location, 2585 had cephalic presentation and 22 (0.84%) had breech presentation. The difference in the frequency of breech presentation between the cornual-fundal and non-cornual-fundal groups was significant (χ(2)=77.78, P<0.001).
CONCLUSION
Cornual-fundal location of the placenta may be an important clue in resolving the etiology of a number of cases of breech presentation at term delivery.
目的
探讨胎盘宫角-宫底位置与足月分娩时臀位的相关性。
方法
本研究于2011年在诺维萨德的妇产科进行。纳入标准为妊娠≥37周分娩、单胎妊娠，以及在妊娠≥37周时经超声检查确定胎盘位于宫角-宫底位置，即胎盘的3/4或更多位于宫角-宫底区域。
结果
在进行的2750次超声检查中，143次显示胎盘位于宫角-宫底位置（频率为5.2%）。86例为头先露（60.14%），57例（39.86%）为臀先露。在其余胎盘非宫角-宫底位置的病例中，2585例为头先露，22例（0.84%）为臀先露。宫角-宫底组与非宫角-宫底组臀先露频率的差异具有统计学意义（χ(2)=77.78，P<0.001）。
结论
胎盘宫角-宫底位置可能是解决许多足月分娩时臀位病因的重要线索。
