Abstract

BACKGROUND:

Some hemodialysis patients develop arteriovenous (AV) fistulas with high flows. This volume overload can result in high-output cardiac failure. To date, predisposing access flow rates are unknown.

METHODS:

A retrospective study of all kidney-transplant recipients at the Medical University of Innsbruck (MUI) from 2005 to 2010 included 797 patients with the following criteria: previous hemodialysis with a native AV fistula or a graft, sufficient function of the kidney transplant up to the time of the data analysis, and follow-up care at the MUI.

RESULTS:

Twenty-nine of the 113 patients (25.7%) needed an AV fistula closure, mostly because of symptoms of cardiac failure. The mean shunt flow in the intervention group was 2197.2 mL/min, whereas the mean shunt flow in the non-intervention group was only 850.9 mL/min. Shunt closures were most frequently made in patients with upper-arm shunts (41.7%).

CONCLUSION:

The necessity of shunt closure is not a rarity. Patients who underwent an AV fistula ligature had high access flows with about 2200 mL/min. As the symptoms of cardiac failure greatly improved after shunt closure, patients with high access flow may benefit from such an intervention.
