Determinants of patency of arteriovenous fistula in hemodialysis patients.

Determinants of patency of arteriovenous fistula in hemodialysis patients. Saudi J Kidney Dis Transpl. 2018 May-Jun;29(3):615-622 Authors: Zouaghi MK, Lammouchi MA, Hassen M, Rais L, Krid M, Smaoui W, Jebali H, Kheder R, Hamida FB, Moussa FB, Fatma LB, Beji S Abstract The arteriovenous fistula (AVF) is the vascular access of the first choice for hemodialysis (HD). Studies on patency of AVF and its affecting factors reveal a high risk for access failure. The aim of this study was to assess the primary and secondary AVF patency and their determinant factors. It was a retrospective, descriptive study conducted in the HD facility of the Nephrology Department in Rabta University Hospital. We included AVF created before December 2009 in end-stage renal disease (ESRD) patients. The end of the follow-up was fixed in December 2013. We included 126 AVFs created in 111 patients; 22.5% were aged >65 years, 39.6% were diabetic, 68.5% were hypertensive, and 26.1% had peripheral vascular disease. The primary patency rates were 78% at one year and 42% at five years. The secondary patency rates were 80% at one year and 69% at five years. Multivariate analysis revealed that the factors affecting the primary patency of AVF were: the use of jugular catheter for longer than three months (odds ratio (OR):1.91, P = 0.044) and a C-reactive protein >5 mg/L (OR: 1.7, P = 0.049). Aging (>65 years) (OR: 2.46, P = 0.042), referral time to a nephrologist...
