lakes, notched, and dopplers - HELP!!

[fatnhap]

Hello all,

I am a new member and me say just how relieved I was to find a website like this. I'm over the moon after browsing through messages and now knowing that no question is ever silly and that we all share such similar concerns. I hope some of you will be able to help me out on this one. Went for a scan as my AFP level was a bit high. After a VERY thorough scan I was told that both uterine artery Dopplers appeared notched and that the placenta appears thick with lakes. They may as well have spoken to me in Chinese ... and then I was told not to worry!! I am 18 weeks pregnant and will be scanned again in 4 weeks. Any of you had this problem? What does it mean and what can it mean for the remainder of the pregnancy?

TIA,
Fatnhap
