【摘要】 目的　探讨胎盘绒毛膜血管瘤的超声特征及其临床意义。方法　 18例胎盘绒毛膜血管瘤患者产前均经二维超声及彩色多普勒超声检查 ,产后经病理证实。结果　 18例胎盘绒毛膜血管瘤均在孕 2 0～ 3 3周超声检查时发现 ,瘤体直径大于 5 .0cm的 9例患者均有不同程度的羊水过多、胎儿发育不良等并发病。其中 2例由于瘤体较大 ,直径大于 8.0cm ,且贴近脐带 ,造成胎儿死亡。另 9例瘤体较小 ,直径小于 5 .0cm ,胎儿和血管瘤共存至分娩 ,胎儿发育正常。结论　超声检查为诊断胎盘绒毛膜血管瘤简便、有效、首选的方法。更多还原

【Abstract】 Objective To study the ultrasonic characteristics of chorioangioma of chorion and its clinical significance.Methods Eighteen cases with chorioangioma were examed by two dimensional ultrasonography and color Doppler flow imaging before delivery and confirmed by postpartum pathology.Results The chorioangioma in all cases were found in 20 to 30 weeks by ultrasonography.Polyhydramnios and underdevelopment of the fetus were associated with the mass larger than 5.0 cm in 9 cases,2 cases of them died due to the mass larger than 8.0 cm and adjacent to the umbilical cord.The other 9 cases with small choriougioma, less than 5.0 cm in lenghth,were still alive with normal development of felus until delivery. Conclusions The ultrasound exam is an effective, simple and the first choice method to detect chorioangioma of chorion.更多还原
