# Pull-through technique through antegrade radial artery puncture without sheath insertion in balloon-assisted radiocephalic arteriovenous fistulas maturation

## TL;DR

A new technique for improving blood vessel access in dialysis patients was tested and found to be as effective as traditional methods.

## Contribution

The pull-through technique through antegrade radial artery puncture without sheath insertion is proposed as an effective and safe alternative for AVF maturation.

## Key findings

- The success rate of the pull-through technique group was 86.7%, comparable to the control group's 89.1%.
- No significant differences were found in hematoma occurrence or primary patency rates between the two groups.
- The pull-through technique proved to be a safe and effective method for AVF maturation.

## Abstract

The aim of this study was to investigate the effectiveness and safety of the pull-through technique through antegrade radial artery puncture without sheath insertion in balloon-assisted radiocephalic AVF maturation.

We retrospective studied a total of 62 patients with immature radiocephalic AVF, who received balloon-assisted maturation in our hospital. 15 patients received pull-through technique through radial artery without sheath insertion and 47 patients received treatment through a regular venous approach.

The success rate of pull-through technique group and control group was 86.7% (13 out of 15), 89.1% (41 out of 46) respectively. There was no significant difference between two groups (P > 0.05). In our study, there were 2 patients in the pull-through technique group and 3 patients in the control group, which had hematoma in the vein puncture site (P = 0.59). There were also no differences in the primary patency rate between two groups at 6 months and 12 months (76.9% vs 70.7%, 38.4% vs 41.5%, respectively, P > 0.05).

The pull-through technique through antegrade radial artery without sheath insertion in promoting radiocephalic AVF maturation is effective and safe.
