PURPOSE: We investigated the characteristics of @entity1 who received long-term hemodialysis/hemodiafiltration ( @entity2033 /HDF) treatment for over 30 years at our group of hospitals and type of vascular access (VA) used. SUBJECTS AND METHODS: As of August 2014, 950 @entity1 were receiving @entity2033 /HDF treatment at one of our hospitals. Of those, we investigated 41 (4.3%) undergoing long-term treatment in regard to their characteristics and VA type. The items subjected to analysis were sex, primary illness, age at time of dialysis initiation, present age, duration (years) of @entity2033 /HDF, type of @entity2548 ( @entity2548 ) and @entity2758 ( @entity2758 ), history of surgery and @entity2548 persistence rate. RESULTS: The subjects consisted of 22 @entity1 and 19 @entity1 , and their mean @entity2033 /HDF duration was 33.4    2.8 years. For primary illness, the majority (n = 31) had chronic @entity631 . The age at time of dialysis initiation was 31.7    7.76 years and present age was 64.5    7.65 years. They had received 3.8 VA surgeries. For present VA type, 23 @entity1 (56.0%) had an @entity2548 and 13 (31.7%) an @entity2758 , while 4 @entity2548 @entity1 (9.7%) had a history of @entity2758 use. One @entity1 (2.4%) had a superficialized artery. The mean @entity2033 /HDF duration of the 13 @entity2758 @entity1 was 7 years and the longest was 18 years. @entity2548 persistence rate estimated by the Kaplan-Meier method was 75% at 30 years after dialysis initiation. CONCLUSIONS: The present results suggest that the ratio of @entity1 with @entity2758 increased with prolonged @entity2033 /HDF treatment. @entity2758 has a higher probability of complications and lower patency as compared to @entity2548 , thus careful management is needed. On the other hand, @entity2758 contributes more to a good long prognosis, as it offers efficient dialysis. In cases of @entity455 due to long-term hemodialysis, it is inevitable to change from @entity2548 to @entity2758 , thus the ratio of @entity2758 @entity1 is expected to increase in cases of long-term @entity2033 /HDF.
