PURPOSE: To clarify the correlation between aberrant gastric venous drainage and a focal spared area at the posterior edge of segment IV in fatty liver by using color Doppler ultrasound (US). MATERIALS AND METHODS: Seventeen patients with fatty liver were examined with gray-scale, color Doppler, and power Doppler US. In one patient with a focal spared area, arteriography and computed tomography (CT) were performed during injection of contrast medium into the right gastric artery. RESULTS: Focal spared areas of fatty liver at segment IV were shown in five of 17 patients. In all five patients with a focal spared area, aberrant gastric venous drainage was observed with color Doppler US. Power Doppler US depicted aberrant gastric venous drainage more clearly than color Doppler US. On the other hand, no definite aberrant gastric venous drainage was seen in the 12 patients who had no focal spared area. In one patient who underwent selective arteriography of the right gastric artery and CT arteriography, aberrant gastric venous drainage into segment IV was directly demonstrated. CONCLUSION: Focal spared areas at segment IV in fatty liver correlate strongly with aberrant gastric venous drainage. Noninvasive imaging methods such as color and power Doppler US are useful for depicting these aberrant drainage veins.
