I think its a 3 months follow up if you have just ballooning and 6 months for stents ?
They should make it more clearer
My azygous vein might of been over looked both times I have been treated in Poland,
The reason I think this is because it was decided that my azygous was fine just from the MRV's not the needed venogram,
And there is also no images on both venograms showing them checking ?
When I last returned in May I said could they check my azygous again but they insisted it was fine,
So i'm left thinking maybe they have missed this but I cant afford to return and dont fancy anymore venogram radation this year
