So I went through surgery for my first fistula 2 weeks ago at Mayo Clinic with a very good Vascular surgeon. Went in for my 2 week check up today and they didn't hear anything - so I went for a sonogram today and sure enough....I could see the blood stopping at a certain point and a big bloodless vein staring me in the face.So what happens now? The tech was not permitted to tell me anything but it was very obvious.Does this happen?I'm sure I will hear from the surgeon tomorrow. Do I do this again? I was born with kidney disease and it runs in my family big time so I am thankful to hit 50 before having to treat it...but not a good start
