Investigation of affecting factors on early artery-venous fistulas failure in patients with less than 20 years old

Introduction: Patients with ESRD (End stage renal disease) are candidate for chronic dialysis. Some of them need to do hemodialysis which one of the ways is to contrive arterio-venous fistulas in extremity via surgery. After fistula maturated and appropriated for needling, we can do dialysis through fistulas. It is possible that fistulas destroy, before maturing. Material and Methods: In this study, patients under 20 years old with ESRD referred by nephrologists for hemodialysis and elected by vascular surgeon, included. Patients investigated for age, sex, body weight (BW), blood pressure (BP), vascular diameter, fistula location, kind of anastomosis, and surgery difficulty that performed by one vascular surgeon. Results: This study was included 30 patients mean age 13±4.6 years. Fistulas location was in snuffbox 17(56.7), antecubital 12 (40), forearm 1 (3.3). Kind of anastomosis was end to end in one patient and side to side in reminder. Early access failure happened in 4 (13.3) patients. Surgery difficulty in early access failure that reported through vascular surgeon was significantly different (p=.039). Conclusion: In our study, difficulty of surgery had been effective in early access failure. Age, sex, fistula location, vascular diameter, use of magnification, and body weight had not been effective in early artery-venous failure.
