Thanks, Kate. It seemed extreme to me but it's really hard to find studies on. This is in the international foundation's website. They have forums too. http://ivpf.org/ J ----- Original Message ----- From: Kate Reynolds To: ozmidwifery@acegraphics.com.au Sent: Tuesday, December 20, 2005 4:07 PM Subject: RE: [ozmidwifery] vasa previa Hi Janet, I’d be very surprised if the fatality rate is so high for undiagnosed vasa praevia. I have only ever seen one responsible for an FDIU at term when SROM’d at home, and I have seen many placentae (?30 - 40) post-birth with massive vessels running through the membranes without incident. In many of those seen,  the membranes tore all the way along side the edge of the vessel. I guess it’s a case of if we know about it, are we obliged to avoid any risk. I think the fatality stats are only relevant when the vessel actually tears but it would seem there are many that never rupture. I have also seen it successfully diagnosed once ruptured and saved by crash c/s on a couple of occasions (obviously in a tertiary referral delivery suite).   Cheers, Kate
