Why Transonic Surveillance is Important – What the Experts Say

“The Transonic Flow-QC Hemodialysis Monitor has benefited numerous dialysis-dependent patients by reducing and, in many cases, eliminating the agony of a clotted AV graft or fistula, thereby facilitating correction of access stenoses on an elective basis that prevents missed dialyses and the need for placing temporary catheters.” Depner T, MD, UC Davis

“QA-based surveillance combining Doppler ultrasound and ultrasound dilution reduces the frequency of thrombosis, is cost effective, and improves thrombosis free and secondary patency in autologous AV.”Aragoncillo I et al, “Adding access blood flow surveillance reduces thrombosis and improves arteriovenous fistula patency: a randomized controlled trial,” J Vasc Access. 2017 Apr 20:0. (Transonic Reference # HD11190)

“Vascular access blood flow monitoring along with preventative interventions should be the standard of care in chronic hemodialysis patients.” McCarley PB et al, “Vascular Access Blood Flow Monitoring Reduces Access Morbidity and Costs,” Kidney Int 2001; 60: 1164-7. (Transonic Reference # HD11190)

“Zero recirculation is a reality, thanks to ultrasound dilution’s ability to separate CPR from access recirculation.” MacDonald JT et al, “Identifying a New Reality: Zero Vascular Access Recirculation Using Ultrasound Dilution,” ANNA J 1996; 23(6): 603-8. (Transonic Reference # HD4T)

“Increased mortality was associated with systemic CI and oxygen delivery index at rest, as well as a drop of these parameters of the end of HD.” Artunc F et al, “Prognostic significance of hemodynamic parameters in hemodialysis patients,” JASN Abstracts 2016; 27: 571A Abstract # FR PO883 (Transonic Reference # HD11003A)

“Regular careful evaluations are necessary in patients with cardiac disease and AVFs. Patients with high flow fistulas (flow greater than 2L/min) and increasing LVEDV are recommended to have a flow reduction procedure on their AVF.”MacRae JM et al, “The Cardiovascular Effects of Arteriovenous Fistulas in Chronic Kidney Disease: A Cause for Concern?” Seminar in Dialysis 2006; 19: 349-352. (Transonic Reference # HD7337A)

“Noninvasive UD screening is very sensitive in detecting hemodynamically significant stenosis and can decrease AV access thrombosis rates.” Ashoor IF et al, “Arteriovenous Access Monitoring with Ultrasound Dilution in a Pediatric Hemodialysis Unit,î Blood Purif 2015; 39(1-3): 93-8. (Transonic Reference # HD10296)

“Hemodynamic monitoring identifies a significant number of HD patients with cardiac impairment who are at risk for increased mortality,” Haag S, Artunc F et al, “Systemic haemodynamics in haemodialysis: intradialytic changes and prognostic significance,”Nephrol Dial Transplant. 2018 Mar 26. (Transonic Reference # HD112305A)

“A thorough cardiac assessment should be performed in patients with CAD prior to placing an AVF. Regular careful evaluations are necessary in patients with cardiac disease and AVFs. Patients with high flow fistulas (flow greater than 2L/min) and increasing LVEDV are recommended to have a flow reduction procedure on their AVF.” MacRae JM et al, “The Cardiovascular Effects of Arteriovenous Fistulas in Chronic Kidney Disease: A Cause for Concern?” Seminar in Dialysis 2006; 19: 349-352.
