Background: Previous nonrandomized studies suggest that prophylactic repair of hemodialyisis arteriovenous (AV) graft stenosis reduces thrombosis rates and increases cumulative graft survival. The present study is a randomized trial comparing prophylactic repair of AV graft stenosis with repair at the time of thrombosis.
Methods: Sixty-four patients with elevated static venous pressure measured in an upper extremity AV graft were randomized to Intervention or Observation.
Background: Static venous pressure elevation has been shown to have both high sensitivity and high specificity for hemodialysis arteriovenous (AV) graft venous anastomosis stenosis. However, it is not known how well static venous pressure elevation predicts subsequent AV graft thrombosis.
Methods: Monthly static venous pressure measurements were made during two consecutive dialysis sessions in all patients with a functioning upper extremity AV graft in two hemodialysis units during a 16-month period.
