JVU 464-160

Pdf Summary

This study examined the role of preoperative ultrasound mapping in arteriovenous fistula (AVF) formation for hemodialysis. The researchers compared AVF outcomes between patients who underwent preoperative ultrasound mapping and those who did not. The study included 158 patients who received an AVF during the study period. The groups with and without ultrasound mapping were similar in terms of baseline characteristics. The early and mid-term AVF patency rates were comparable between the two groups, although there was a trend towards more favorable outcomes in the mapping group. However, this trend did not reach statistical significance. Cox regression analysis did not identify any factors as significant predictors of AVF survival.<br /><br />The findings of this study suggest that routine preoperative ultrasound mapping may not provide significant benefits in AVF formation for hemodialysis. The authors note that ultrasound mapping is safe and widely available, and further well-designed trials with sufficient power are needed to confirm its role in AVF creation. The study acknowledges its limitations, including its retrospective design and relatively small sample size. Despite these limitations, the study contributes to the ongoing debate on the use of ultrasound mapping in AVF formation.
