Re: [ozmidwifery] vasa previa

Hi Janet,   I probably have seen about 10 unknown  vasa previa post birth.  All laboured without incident. Two of those were also ARM's by doctors speeding up the birth process, and only realised once the placenta was delivered   Very lucky doctors if you ask me! ----- Original Message ----- From: Janet Fraser To: ozmidwifery@acegraphics.com.au Sent: Tuesday, December 20, 2005 1:26 PM Subject: Re: [ozmidwifery] vasa previa 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
