Beautiful veins. I had vein mapping and it was all for nothing (in my opinion). My first fistula in my left wrist didn't work due the the vein being "too small".
And my 2nd worked up until transplant (never used the fistula) and the vein got big, but never protruded due to the vein being too deep. He even moved the vein up, but apparently not 'up' enough. I'm thankful I never had to do dialysis, but the vein mapping was worthless due to the two problems I just mentioned. Good Luck!!
