Function of color Doppler ultrasonography in monitoring the complications of arterialvenous fistula in elderly patients / 中华老年医学杂志

ABSTRACT

Objective To evaluate the clinical application of color Doppler ultrasound in monitoring the complications of arterialvenous fistula in elderly patients. Methods The 36 hemodialysis patients over the age of 60 were enrolled, including 27 cases of autologous arteriovenous fistula and 9 cases of artificial vascular graft arteriovenous fistula. The ideal vascular access could not be established in the 9 cases due to their own conditions. Color Doppler ultrasonography was used to test the function of arteriovenous fistula and to observe its complications. Results The arteriovenous fistula in 26 cases (72.2 %) was patent in 36 elderly hemodialysis patients. The 6 cases (22.2 % ) in 27 of autogenous arteriovenous fistula and 4 cases (44.4 % ) in 9 of artificial arteriovenous fistula had complications. Conclusions Ultrasound can clearly show the position, pathway, lumen and blood flow dynamics of the transplanted autologous or artificial blood vessels in arteriovenous fistula so as to evaluate the effects of blood dialysis in elderly patients and to detect the complications for clinical reference.
