Ultrasound characteristics of side-to-end arteriovenous fistula at forearm in chronic renal failureforperiodical hemodialysis

SUMMARY

Objective: To assess ultrasound characteristics of radiocephalic fistula at 2 and 3weeksafter operation in chronic renal failure with periodical hemodialysis.

Methods: This study was conductedon 34 patients with indication of periodical hemodialysis due to chronic renal failure from April, 2016 to July, 2017 at Hemodialysis Department in Hue Central Hospital. These patients were operated to createside-to-end radiocephalic fistula at forearm and examed with ultrasound at week 2 and 3after operation.

Results: The mean age was 45,79 ± 14,59 (mean ± SD); 47,10% male and 52,90% female patient. Diabetes was presented in 5,88% of the patients. The mean diameter of vein was 4,96 ± 0,88 mm at week 2 and 5,40 ± 0,99 mm at week 3 (p < 0,05);venous flow volume was 531,33 ± 162,40 ml/p and 666,56 ± 260 ml/p at week 2 and 3, respectively (p < 0,05). The rate of mature fistula at week 3 after operation was 82,35%. Most of the fistula complication was stenosis at the arterio-venous anastomosis and the draining veins.

Conclusion: Ultrasound can assess the flow through arteriovenous fistula, detect several early complications which cause abnormal fistulas and help formanagement and treatmentof patients.
