Abstract
PURPOSE
Access-related morbidity contributes substantially to the costs of hemodialysis. The aim of this study was to examine the outcomes of initial hemodialysis access surgery at a single center in Singapore and to analyze factors which might influence survival of the surgically-created access.
METHODS
Patients undergoing their first hemodialysis access operations between January 2003 and December 2007 were retrospectively identified. Primary and assisted primary patency rates were determined by the Kaplan-Meier method. Data on age, sex, diabetic status, and prior tunneled central venous catheter (CVC) use were analyzed against the outcome of arteriovenous fistulas (AVF).
RESULTS
During the study period, 410 primary upper limb access operations were performed: 297 forearm AVF (72.4%), 91 upper arm AVF (22.2%), and 22 arteriovenous grafts (AVG; 5.4%). Men comprised 55.4%, 271 (66.1%) had diabetes, and 316 patients (77.1%) came to surgery with pre-existing CVC. Sixty-two percent of forearm AVF and 67% of arm AVF were used successfully. Age, sex, diabetes, and prior use of a CVC did not significantly affect the ability to use an AVF. Only in the female diabetic subgroup was an earlier loss of primary assisted patency of AVF recorded.
CONCLUSIONS
In our Asian population, we have demonstrated AVF patency rates equivalent to those of international centers. We now face the challenge of achieving a higher rate of pre-emptive AVF placement with a subsequent reduction in CVC use.
