BACKGROUND
Placental chorioangiomas are the most common tumors of the placenta, occurring in 1% of all pregnancies. With the increasing use of ultrasound, prenatal recognition of these tumors is becoming more common.
CASE
A 36-year-old woman presented at 28 weeks' gestation with an intrauterine mass suggested by color flow and Doppler studies to be a vascular tumor. Because of the association of these findings to nonimmune fetal hydrops, management included umbilical blood sampling and intravascular transfusion for fetal anemia. This intervention temporarily corrected the hydrops and significantly prolonged the pregnancy.
CONCLUSION
Color flow mapping and Doppler flow studies of intrauterine tumors associated with fetal nonimmune hydrops can be helpful in both diagnosis and management.
背景
胎盘绒毛膜血管瘤是最常见的胎盘肿瘤，在所有妊娠中发生率为1%。随着超声检查的日益普及，这些肿瘤的产前诊断越来越常见。
病例
一名36岁女性在妊娠28周时就诊，彩色血流和多普勒研究提示子宫内有一肿块，考虑为血管性肿瘤。由于这些发现与非免疫性胎儿水肿有关，处理措施包括脐血取样和对胎儿贫血进行血管内输血。该干预措施暂时纠正了水肿并显著延长了孕周。
结论
对与胎儿非免疫性水肿相关的子宫内肿瘤进行彩色血流图和多普勒血流研究，对诊断和处理均有帮助。
