Plastic cannulas for hemodialysis have been used in Japan for many years; however, effect of early cannulation with plastic cannulas on arteriovenous fistula (AVF) patency is unknown. We studied if early cannulation with plastic cannulas would affect AVF patency.


ESRD patients who underwent primary AVF operations were divided into an early cannulation group with first cannulation time (FCT) within<10 days and a late cannulation group with FCT≥10 days.The Kaplan-Meier method and multivariable Cox regression models were used to investigate AVF patency.


122 patients were enrolled in the study (mean age,72.5 yr;64.8%male;52%diabetes mellitus;89%RCAVFs), median FCT was 6 days. Kaplan-Meier analysis showed that there was no statistically significant between-group difference in primary or secondary patency rates. Early cannulation was not found significantly associated with primary patency or secondary patency after age, gender, the presence of diabetes mellitus, hypertention and being on hemodialysis were adjusted.


Early cannulation with plastic cannulas might not affect AVF patency, maybe we can cannulate AVFs earlier than 10 days after AVF creation to avoid the use of central venous catheters.
