In 13 chronic hemodialysis patients who required frequent arteriovenous recannulation, the technique of internal suture stabilization was used. To achieve maximum cannula-vessel stability, two nonabsorbable sutures were passed through the cannula wall at the proximal end of the silicone rubber outer cannula where it overrides the Teflon tip, and then secured to the underlying muscular fascia. None of the individuals who handled the cannulas daily were aware that the stabilization procedure had been performed.

Mean cannula survival in the nonstabilized group was 85.2 days and in the suture-stabilized group was 242.2 days, a highly significant difference. In addition, these patients have shown a marked reduction in the frequency and severity of cannula infection.
