attry and vein to liver concected HELP

I have high liver emzines( not fatty )and have had for sometime.  I am almost 7 years out from RNY.  My Dr. a (spealist I had to fight my regular Dr. for) says (after much testing and he is doing more) Anyway it looks like an arttry and vein have grown together due to mistake during surg.causeing too high of pressure on the liver which could explode if not fixed and can continue to ruin the liver at best.  Has this happened to anyone else and if so where can I read more on this?   I have searched the internet. and found nothing. My old e-mail is no longer any good here and I do not know how to change it so I will be checking back.  From time to time.  Thanks.  Cheryl

Don't know about the liver, but it might be an A-V fistula.  I had that after a kidney biopsy when the renal artery and renal vein grew together.
