A single treatment, using Far Infrared light improves blood flow conditions in arteriovenous fistula

November 1, 2017

Abstract

BACKGROUND: A native arteriovenous fistula (AVF) is recommended for angio access in patients on chronic hemodialysis

(HD). Fistula patency has been improved by exposure to Far Infrared light (FIR).

OBJECTIVE: To investigate whether a single FIR treatment could alter blood velocity, AVF diameter or inflammatory

markers.

METHODS:Thirty patients with a nativeAVF in the forearm were included. Each patientwas his/her own control. Ultrasound

(US) examinations were performed before and after a single FIR treatment.

RESULTS: A single FIR treatment resulted in a significant increase in blood velocity over the AV fistula from a mean of

2.1 ± 1.0 m/s to 2.3 ± 1.0 m/s (p = 0.02). The diameter of the arterialized vein became wider; 0,72 cm ± 0.02 to 0,80 cm ± 0.02,

(p = 0.006). The increase in fistula blood velocity correlated positively with base line serum- urate p = 0.004) and the increase

in venous diameter with the base line plasma orosomucoid concentration (p = 0.005).

CONCLUSIONS: This study shows that a single FIR treatment significantly increasedAVF blood velocity and vein diameter.

Thus, one FIR treatment can help maturation of AVF in the early postoperative course.

FIRAPY to Exhibit at 70th JSDT Annual Meeting in Yokohama

June 17, 2025
We are pleased to announce that FIRAPY will be exhibiting at the 70th Annual Meeting of the Japanese Society for Dialysis Therapy (JSDT) , to be held in OSAKA , Japan , from June 27-29, 2025 . 📍 Booth No.: ⑩-96 📅 June 27–29, 2025 📌 Osaka International Convention Center 🔗 Event Website (Japanese) FIRAPY is now adopted by over 200 dialysis facilities across Japan , where it has been used in daily clinical practice to support fistula function maintenance and foot care . With this extensive local experience, FIRAPY has become an important part of non-invasive treatment for Japanese HD patients. We look forward to sharing our latest clinical insights and field experiences at JSDT 2025. If you are attending, we warmly welcome you to stop by Booth ⑩-96 and learn more about how FIRAPY is making a difference in dialysis care. See you in Osaka!
