Effect of anastomosis angle on the localization of disturbed flow in ‘side-to-end’ fistulae for haemodialysis access
Nephrology Dialysis Transplantation, 07/16/2012
Ene–Iordache B et al. – The authors have found that in ‘side–to–end’ radial–cephalic arteriovenous fistulas (AVFs) for haemodialysis, the anastomosis angle does impact on the local disturbed flow patterns. Among the four geometries the authors considered in this study, the smaller angle (30°) would be the preferred choice that minimizes the development of neointima. Clinicians should consider this at the time of AVF creation because the anastomosis angle is in part amenable to surgical manipulation.
