A major cause of morbidity for haemodialysis patients is vascular access failure and/or occlusion. It is commonly believed that increased frequency of dialysis sessions, among other factors, might lead to higher rates of fistula complications. To evaluate if patients on daily haemodialysis carry a higher risk of vascular access occlusion, we examined the raw incidence rate of access occlusion and the survival function of native vascular access in patients undergoing daily dialysis (DD - N. =24) as compared to patients on standard three times a week haemodialysis (TWD-N. =198). The number of thrombotic events in the first group was 2 (8%) whereas in the second group we observed 76 (38%) access problems (8%) (p<0.008). The mean vascular access survival before occlusion was 1307 days in TWD and 1388 days in DD. Our data clearly shows that daily dialysis should not be considered a risk factor for access occlusion.

Abstract
A major cause of morbidity for haemodialysis patients is vascular access failure and/or occlusion. It is commonly believed that increased frequency of dialysis sessions, among other factors, might lead to higher rates of fistula complications. To evaluate if patients on daily haemodialysis carry a higher risk of vascular access occlusion, we examined the raw incidence rate of access occlusion and the survival function of native vascular access in patients undergoing daily dialysis (DD - N. =24) as compared to patients on standard three times a week haemodialysis (TWD-N. =198). The number of thrombotic events in the first group was 2 (8%) whereas in the second group we observed 76 (38%) access problems (8%) (p<0.008). The mean vascular access survival before occlusion was 1307 days in TWD and 1388 days in DD. Our data clearly shows that daily dialysis should not be considered a risk factor for access occlusion.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
