Relationship between gallbladder wall-typing and the main portal vein, right portal vein hemodynamics in patients with liver cirrhosis with high-frequency ultrasound / 中国医学影像技术

Objective To investigate the relationship between gallbladder wall-typing and the main portal vein, right portal vein hemodynamics in patients with liver cirrhosis. Methods The main portal vein, right portal vein hemodynamics and the thickness of gallbladder wall were examined in 69 patients with cirrhosis and 30 normal subjects (control group) with two-dimensional ultrasound, color Doppler ultrasound and high-frequency ultrasound. According to the gallbladder wall-typing, 69 patients with liver cirrhosis were divided into not thickened, simple thickening and bilateral subgroups. The paremeters of hemodynamics and the thickness of gallbladder wall were compared among groups. Results There was statistical difference in thickness of gallbladder wall among all 3 subgroups. Statistical difference of the diameter of main portal vein (D_(pv)) was found among the subgroups (P0.05). There was positive correlation between the gallbladder wall thickness and D_(pv) (r=0.886, P<0.01). Conclusion The gallbladder wall-typing has no correlation with the right portal vein hemodynamics, but is related with the main portal vein hemodynamics. The bilateral and the thickness of gallbladder wall can indirectly reflect the hemodynamic changes of main portal vein. Obstruction to flow of cystic vein is not the main hemodynamic cause for the gallbladder wall changes in patients with liver cirrhosis and portal hypertension cause, indicating that there may be some intrinsic mechanisms of this phenomenon.

3.0 cm in diameters.Contrast-enhancement CT showed tumors with abundant blood vessel,1 case appeared as uniform enhancement and was difficult to distinguish between tumor body and internal carotid and external carotid because of the iso-density of them.On MRI,the flow void blood vessels inside the tumors could be identified and internal carotid and external carotid separated.MRA displayed all the relation between the tumors and carotid and its branches.DSA could demonstrate the supply arteries of the tumors.Conclusion Ultrasonics,CT,MRI and DSA have own definitely characteristic value in diagnosing carotid body tumor.
