Fig. 9.8  Aberrance of the celiac artery

2.3.1\ Scanning Method

The method is the same as that shown in Sect. 2.1.1.

2.3.2\ Section Structure

Ao, CA, SMA.

2.3.3\ Measurement Method and Normal Value

The diameter and color Doppler spectrum of the CA and SMA can be measured on this view. If the patient is fasted, the spectrum of the CA shows a two-phase pattern with a relatively low resistance index (RI). The spectrum of the SMA shows a relatively high RI.

2.3.4\ Clinical Application Value

The CA and SMA can arise together from the Ao; this occurs in fewer than 1% of the population. If the SMA arises from the CA, a severe stenosis of the CA may cause symptoms of mesenteric ischemia.
