Using advanced ultrasound to predict outcomes of vascular access in kidney disease patients

Using Ultrasound 2D Strain Speckle Tracking, 2D Shear Wave Elastography and Transonic Flowmeter as Diagnostic and Potential Predictor Tool for Arteriovenous Fistula Outcomes With End Stage Renal Failure.

Observational Imperial College London · NCT04141358

This study is testing whether advanced ultrasound measurements can help predict how well kidney disease patients will do after getting a special type of surgery to create a blood vessel for dialysis.

What this trial studies

This observational pilot study focuses on patients with end-stage renal disease (ESRD) who are referred for arteriovenous fistula (AVF) procedures. The research team will collect clinical data and perform advanced ultrasound measurements to assess factors such as blood flow, vessel diameter, and arterial stiffness before, during, and after the AVF surgery. The study aims to evaluate the relationship between these ultrasound parameters and the success of the AVF, providing insights into potential predictors of AVF outcomes. Data will be gathered over a 21-month period, including pre-operative assessments and post-operative evaluations at six weeks.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 90 with end-stage renal disease and a glomerular filtration rate of less than 30 ml/min/1.73m2.

Not a fit: Patients who are under 18 years old, over 90 years old, or do not have end-stage renal disease will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the prediction of AVF outcomes, leading to better vascular access strategies for patients undergoing dialysis.

How similar studies have performed: While there have been studies on vascular access and ultrasound applications, this specific approach using advanced ultrasound techniques for predicting AVF outcomes is relatively novel.
