【摘要】：目的探讨帆状胎盘的超声表现和诊断价值。方法对34例经手术病理确诊的帆状胎盘患者的彩色多普勒超声声像图进行回顾性分析,总结其特点。结果 34例帆状胎盘的患者中,术前超声诊断25例,其中3例合并前置血管,2例为静脉前置,1例为动脉前置。25例帆状胎盘的超声表现:扫查整个胎盘的胎儿面,均未见脐带与胎盘的附着点,彩色多普勒超声显示脐血管自脐带入口处延胎膜下走行一段距离后进入胎盘,脐带入口处无胎盘组织,脐血管进入胎膜后分成数支,帆状胎盘合并血管前置时表现为宫颈内口上方长管状无回声区,CDFI可见宫颈内口上方条状血流信号。结论彩色多普勒超声诊断帆状胎盘经济、无创、准确,可作为首选的诊断方法。
[Abstract]:Objective to investigate the ultrasonographic manifestations and diagnostic value of the sail placenta. Methods the ultrasonographic features of 34 patients with sail placenta confirmed by operation and pathology were analyzed retrospectively and their characteristics were summarized. 25 cases were diagnosed by ultrasonography before operation, of which 3 cases were complicated with venous previa in 2 cases. One case was artery preposition. 25 cases of sails placenta were detected by ultrasonography: no umbilical cord and placenta attachment was found in the fetal surface of the whole placenta. Color Doppler ultrasound showed that the umbilical cord blood vessel entered the placenta after a distance from the entrance of the umbilical cord to the fetal membrane, and there was no placental tissue at the entrance of the umbilical cord, and the cord blood vessel was divided into several branches after entering the fetal membrane. The sails placenta combined with vascular preposition was characterized by long tubular nonechoic area above the inner orifice of the cervix. Conclusion the diagnosis of sails placenta by color Doppler ultrasound is economical, noninvasive and accurate, and CDFI can show the signal of blood flow over the inner orifice of the cervix. It can be used as the preferred diagnostic method.
