Introduction: Since Brescia and Cimino(1966) posted AV Fistula technique, there has been increase of long term survival of patients with End Stage Renal Disease (ESRD). AV fistula has its own set of indications, benefits, and complications. Purpose: To show AV Fistula creation outcomes, complications and its related comorbidities in Ben Mboi District Hospital, Ruteng Flores Indonesia Method: An analytical study design using a cross sectional approach was employed in this study. Using medical record data from 2019 to 2022, all men and women who received hemodialysis through AV Fistula were included. Bivariate analysis was carried out from baseline data such as age, sex, comorbidities, location of an av fistula (AVF), previous dialysis insertion with complications that arise using Chi-square. Results: Age, sex, hypertension and AV Fistula creation location has no significant correlation with complications such as failed to mature, thrombosis, infection, venous hypertension. Diabetes mellitus has a significant correlation with occurrence of failed to mature (p=0.012), thrombosis (p=0.014), venous hypertension (p=0.08). Obesity has a significant correlation with occurrence of failed to mature (p=0.000), thrombosis (p=0.000). Previous insertion of CDL in right subclavian vein has a significant correlation with occurrence of venous hypertension (p=0.000). Conclusion: Diabetes mellitus has a significant correlation with occurrence of complications such as failed to mature, thrombosis and venous hypertension. Obesity has a significant correlation with occurrence of failed to mature and thrombosis. History of CDL insertion in right subclavian vein has a significant correlation with venous hypertension.

“…[5][6][7][8] Although VA duplex ultrasonography (DUS) is currently a method that is acquiring a greater relevance, it is not available in all centers and there are several disadvantages dependant on the operator's experience and accuracy. 9 Classic ultrasound dilution (UD) methods allow detection of AVF risk through a simple method with computer-calculated results. In addition, it is operator-independent and limited training is required.…”

Hemodialysis vascular access flow measurements by the novel DMed NephroFlow® device: A comparative study with Transonic®

et al. 2022

Introduction: The current Spanish Clinical Guidelines on Vascular Access for Hemodialysis support the need for surveillance and monitoring of vascular access (VA) to avoid complications. Ultrasound dilution (UD) methods are accepted for the evaluation of VA flow and Transonic® has established the gold standard method for the measurement. The DMed NephroFlow (NIPRO®) device, based on UD method has recently been incorporated. We report a comparative study between the classic Transonic® versus the new NephroFlow® device. Material and methods: For two consecutive months, measurements of VA flow using both referred systems were performed in patients with a native arteriovenous fistula (AVF) or a graft (AVG) on hemodialysis (HD) in our unit. Both studies were undertaken according to the usual recommendations: VA flow of 250 ml/min, ultrafiltration rate without modifications, both needles in the same vein, and always in the first hour of the HD session. Results: Forty-five patients were included: 17 women and 28 men, mean age of 67 ± 12 years. Thirty patients were diabetic. The baseline meantime on HD was 51 ± 39 months (range: 3–163). Type of VA was: 17 patients radio-cephalic AVF, 17 brachiocephalic AVF, 7 brachiobasilic AVF, and 3 with a graft. The mean flow estimated by the Transonic® was 1222 ± 805 ml/min and the estimated flow by the NephroFlow® device was 1252 ± 975 ml/min. Good reliability between Transonic® and NephroFlow® was observed, with a reliability index of Cronbach’s Alpha of 0.927 and an Intraclass Correlation Index of 0.928. Conclusions: The NephroFlow® device seems comparable with the accepted gold standard UD method for estimating VA flow. More studies must be performed to verify these results. However, they should be considered for the surveillance and monitoring of VA flow, in agreement with the Spanish Guidelines.
