RESUMEN
Decreased use of native arteriovenous fistulas and an increased reliance on synthetic grafts as permanent dialysis access have accompanied the growth of the dialysis population in the United States, but not at our institution. Possible reasons for this difference were studied in a cross-sectional analysis in August of 2000. There were 51 chronic dialysis patients, all of whom had their access placed by the same surgeon; 75% of them were dialyzed through an arteriovenous fistula, which compares well with the 23% prevalence at the national level. Among our patients, 57% were diabetic, 98% had a history of hypertension, 35% had amputations or arterial bypass surgery, 37% had coronary artery disease, 12% had suffered a stroke, 35% were active smokers, and 22% had a history of intravenous drug use. The high prevalence of arteriovenous fistulas, despite so many comorbid conditions, suggests that the presence of a skilled and experienced surgeon may be more predictive of better dialysis access than other factors.
