Collateral Ligation in Failing Fistulas
Sponsor: Massachusetts General Hospital
Summary
Arteriovenous fistulas (AVFs) for hemodialysis often fail to become usable due to failure to mature (FTM). The most common cause is narrowing of the artery or vein (stenosis). Another potential cause is the presence of collateral or side branch veins that steal blood flow from the main fistula channel. Some believe that occluding these veins might help maturation of those failing AVFs. To evaluate if this actually works, patients with FTM will be randomly assigned to side branch vein ligation (or not), and rates of AVF maturation of the two groups will be compared.
