Figure 7: Ultrasound findings indicate this recently created transposed basilic fistula is maturing well. The scale to the right of the image confirms that a 5-cm length is superficial enough for easy cannulation, lying 0.5 cm or less from the surface of the skin. The diameter measures 0.73 cm. With PSV of 189.9 cm/sec and EDV of 123.9 cm/sec, a volume-flow of 1792 mL/min has been calculated by a software package incorporated into the ultrasound equipment. These details are shown in the upper left hand corner.
