Background:

The autologous arteriovenous fistula (AVF) is the best vascular access modality for hemodialysis due to its long-term primary patency.

Objective:

To evaluate the preoperative ultrasonographic mapping and determine if performing this assists to reduce the maturation time, compared to those without it.

Material and methods:

A retrospective, descriptive and analytical study of the patients with fistula was carried out without prior ultrasonographic mapping being done with those patients who underwent AVF using ultrasound.

Results:

A total of 104 patients were analyzed, of which 51 corresponded to the preoperative USG group and 53 to the clinical group. No significant differences were observed between both groups. The group that underwent ultrasound, 35 (33.7%) matured and in the group with only physical examination, 35 (33.7%) matured. However, it was shown that patients who underwent a previous ultrasound matured earlier than those who did not.

Conclusions:

Preoperative ultrasound demonstrated to be an indispensable tool, since it allows a better planning and progress in the results of fistulas.
