LONG-TERM SURVIVAL OF VASCULAR ACCESSES IN A LARGE CHRONIC-HEMODIALYSIS POPULATION

Complications associated with vascular accesses account for approximat ely 30% of hospital admissions for chronic hemodialysis patients. Long -term patency of access was evaluated in 76 patients, without diabetes mellitus, who had been on dialysis for at least 3 years and 41 patien ts, with diabetes mellitus, who had been on dialysis for over 2 years. Fistulas functioned longer than grafts (58 vs. 22 months, p<0.01, in nondiabetics and 70 vs 22 months, p<0.01, in patients with diabetes). Declotting or revision of restored graft function for short periods of time (<6-10 months) and subsequent declotting was ineffective. Infect ions were uncommon in grafts (1 per 13.5 years of dialysis) and in fis tulas (1 in 200 years of dialysis).
