Fig. 9.23  Accessory renal artery

5.7.1\ Scanning Method

The patient should be in a lateral position. The coronal section of the kidney is shown, and the accessory renal artery is detected on the color Doppler flow image.

5.7.2\ Section Structure

Longitudinal view of the accessory renal artery, longitudinal section of the Ao, coronal section of the kidney.

5.7.3\ Measurement Method and Normal Value

The accessory renal artery is thinner than the main renal artery; the spectrum patterns are the same as those of the main renal artery.

5.7.4\ Clinical Application Value

The accessory renal artery can arise from the Ao or the main renal artery and can reach the kidney at the upper or lower pole of the kidney. The track of the accessory renal artery is not fixed and is sometimes hard to detect by ultrasound. The incidence of an accessory renal artery is as high as 41.8% (the left side is more common); a stenosis in the accessory renal artery can also lead to renal vascular hypertension.
