Özet: Alm: Hemodialysis tor the treatment of chronic renal failure.is the most common and classical technic. For providing effective and longterm dialysis it is essential to create an arteriovenous fistula which works optimal. The aim of this study was to assess the effect of adventitial dissection and hidrostatic dilatation on the maturation of arteriovenous fistula lor hemodialysis. Material and Method: Between May 1999 and June 2001, 60 patients with chronic renal failure have been enrolled at the Department of General Surgery of Ankara University. Mean age was 45.5, ranged 20-65. Twelve patients we re excluded because of technical or anatomical failure. 48 patients were divided into four groups: in group I patients were performed adventitial dissection and hydrostatic dilatation. in group il patients were performed only hydrosta tic dilatation. in group 111 patients were performed only adventitial dissection. in group iV patients were performed ne ither adventitial dissection nor hydrostatic dilatation. The diameter of artery, vein and blood flow of arteriovenous fistula were assessed on the postoperative first day by Doppler USG. The first day of hemodialysis was recorded. Results: No statistical significant difference was found between four groups lor diameter of artery, blood flow and first day of hemodialysis. There was no thrombosis in the early period but one patient in group I and one patient in group il developed thrombosis within 6 months after operation. Concluslon: Our findings indicate that adventitial dissection and hydrostatic dilatation are ineffective and unneces sary to provide early hemodialysis.
