Abstract

This paper proposes a signal processing method for evaluating arteriovenous shunt (AVS) stenosis in hemodialysis patients. AVSs are surgically created pathological or physiological fistulas serving as access routes for end-stage renal disease patients. The distinct and periodic bruit of vascular shunts is clearly audible over the access routes. Thus, a bruit spectral analysis could be considered a valuable noninvasive method for quantifying the severity of vessel stenosis. We intend to determine a more precise relationship of phonography to stenotic lesions and the flow velocities; therefore, we must conduct an additional in vitro study to simplify the relationships. To achieve this goal, we must set up a specific mock to simplify the blood flow condition and analyze the stenotic lesions-to-flow relationship.
