Summary

Arteriovenous fistulas (AVF) are considered essential and the primary vascular access for end-stage renal disease patients to receive hemodialysis (HD) treatment. The maturation failure rate of AVFs is approximately 23%. The aim of our study is to compare intraoperative fistula flow and measurements of vascular structures' diameters with postoperative fistula maturation, following the completion of the fistula operation, to reveal the relationship between them. Providing insights into the need for intraoperative intervention and/or postoperative fistula management based on these measurements is intended to contribute to the literature by offering predictions and perspectives.

  • Arteriovenous Fistula

Interventions

Doppler Ultrasonography Assessment

Preoperative data will be collected from the latest available data within the last month. Preoperative Doppler ultrasonography venous mapping for all patients will be performed by experienced Radiology Specialists. AVF flow measurement will be performed intraoperatively and at the 6th week postoperatively using Doppler ultrasonography (B-Mode and duplex ultrasound on the LOQIC; GE Healthcare Technologies, Milwaukee, Wisconsin, United States). For each patient, AVF flows will be recorded by taking at least 3 measurements of AVF flow, depth, and vascular diameters at 2, 5, 10, and 15 cm proximal to the AVF anastomosis, and arithmetic averages will be calculated. AVF flow will be expressed in "ml/min," and the vascular structure diameters and the distance of AVF from the skin will be indicated in "mm." AVF depth will be calculated as the distance from the skin to the anterior wall of the AVF.
