i'm a newbie here on behalf of my sis, who had her doppler done at melbourne radiology by Dr Julie Gregg recently. I read with great interest and am really encouraged that so many aussies are pushing for this testing and treatment, and hope that everyone who gets the procedure done gets continuing and lasting improvement
. I guess this is directed to those folks who have had inconclusive or discouraging doppler results, and whether there was still hope through further testing, MRV, venogram, etc. The head radiographer and Dr Gregg herself mentioned to us and our GP that the doppler results were normal, apart from a slight abnormality on the right jugular which is insignificant. After recieving the report, it seems there is an abnormality with the right IJV flow, and we are anxious to see whether this is worth investigating further. Our GP has no idea on this topic, had no real cardiovascular person he could refer us to and basically relayed what the radiographer told him. I have pasted the results below, and would greatly appreciate any comment from anybody as to whether the stenosis mentioned is worth investigating further, or whether the radiographer is spot-on in his analysis and we should just move on.. we are grateful for any advice and wish all aussie msers success in their ccsvi quest! many thanks.

Internal jugular vein stenosis with peak systolic velocities of 74cm/sec and prestenotic velocities of 20cm/sec correlate with a greater than 50% stenosis.
Reflux: (>0.88 sec): No
DCSA IJV (N>0): Supine – Erect CSA IJV Right: Normal Left: Normal
1. Bilaterally reduced flows in the internal jugular veins in the supine position however moreso on the right.
2. Mildly increased flows of the left internal jugular vein in the erect position and left vertebral vein is of uncertain significance.
3. Right internal jugular vein stenosis greater than 50%.
