case_images: Spectral flow analysis of the radial artery revealed a significant increase in diastolic velocity in the segment proximal of the fistula ( Figure 1 ), with reduction of diastolic velocity to normal levels beyond the fistula.

case_images: A duplex scan showed that diastolic velocity in the segment proximal to the fistula had normalized ( Figure 3 ) and blood gas analysis results were as follows: pH 7.426; PCO2 34; PO2 64.6; bicarbonate 22; and oxygen saturation 93.3.
