Eddie, good luck to you. I hope this IR doctor uses the Zamboni Protocol.

That was fast. Let us know how you make out when you get the results. They can only to the jugulars with the ultrasound. Only the 3-D MRV color Doppler can see the Azygous vein in the chest wall behind the breast bone.

I hope that is the Doppler you get. Too bad you can't go straight to the Venagram, that way they can fix anything they see, during that procedure.
Best of luck to you.
