ABSTRACT
OBJECTIVE: The aim of this study is to compare the rate of primary patency and secondary patency achieved by ulnar-basilic arteriovenous fistula (UBAVF) and radiocephalic arteriovenous fistula (RCAVF) in the maintenance of hemodialysis access. METHODS: This retrospective analysis consists of 365 patients who had a forearm UBAVF or RCAVF between January 2012 and December 2015. Of these patients, 44 patients were treated with UBAVF, while 321 patients were treated with RCAVF. Demographics, primary patency, and secondary patency were documented and compared. RESULTS: Primary patency rates at 1 and 2 years were 77.2% and 63.9% in group UBAVF and 88.1% and 71.3% in group RCAVF, respectively. Secondary patency rates at 1 and 2 years were 93.0% and 78.8% in group UBAVF and 98.7% and 80.9% in group RCAVF, respectively. The Kaplan-Meier analysis showed that the primary and secondary patency rates were all without statistical difference between the 2 groups. CONCLUSION: Given the similar patency rate between UBAVF and RCAVF, the UBAVF could be considered as a reliable alternative when an RCAVF is not possible.

Objective To study the clinical use of the ulnar-basilic arteriovenous fistula as a long-term vascular access in patients with hemodialysis.Methods The clinical data of 36 patients with 1-year follow-up who had a wrist ulnar-basilic arteriovenous fistula formed in China-Japan Friendship Hospital from January 2013 and December 2014 were retrospectively analyzed.The outcomes for this study including the surgical results,complication rate of ulnar-basilic arteriovenous fistula,immediate patency rate,average maturation time,1-year primary patency rate and true patency rate were analyzed.Results Thirty-four cases patients got successful ulnar-basilic arteriovenous fistula formed with palpable vascular thrill.There were no death cases and no severe cardio-cerebrovascular complications.No infection,heart failure,distal swelling and ischemia occurred.The immediate patency of ulnar-basilic arteriovenous fistula was 94.4%(34/36),the average maturation time was (67±4) d,1-year primary patency rate was 63.9%(23/36),and true patency rate was 67.6%(24/36).Conclusion Ulnar-basilic arteriovenous fistula with adequate 1-year primary patency and low risk of infection and complications can be a viable alternative as the hemodialysis vascular access.
