|
Purpose : As the proportion of patients with diabetes and old age increases, the use of arteriovenous graft (AVG) is increasing. However, there are few data about the comparison of the patency rate of native arteriovenous fistula (AVF) to that of AVG in Korea. We compared the outcome of native AVF to that of AVG with analysis of the factors affecting the patency of the permanent vascular access in use.
Methods : A retrospective database of all vascular access related procedures performed from January 1, 2003 to December 31, 2003 was established. We evaluated the primary unassisted and cumulative access patency rate with analysis of patency-related factors. We also evaluated the primary failure rate of AVF and AVG.
Results : 196 new vascular access surgeries were performed during the period. 14 cases were excluded due to loss of follow-up. 142 native arteriovenous fistulas (78%) and 40 grafts (22%) were constructed. The primary failure rate was similar between AVF and AVG group. The primary unassisted
(78%, 72%, 68% vs. 62%, 41%, 22% at 1, 2, 3 year; p<0.001) and cumulative patency rate (93%, 88%, 85% vs. 84%, 74%, 73% at 1, 2, 3 year; p=0.087) were better in AVF group than in AVG group. The factors affecting the patency of vascular access were the type of vascular access and planned construction of permanent vascular access.
Conclusion : Patency of native AVF as the permanent vascular access was better than that of AVG. Planned construction of permanent vascular access improved the patency of the access. |
