Abstract:
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 (P<0.01), except between not thickened and simple thickening subgroup. Statistical difference of the velocity of the main portal vein (V_(pv)) was found between simple thickening subgroup and control group, as well as between bilateral subgroup and the control group (P<0.01). Statistical differences of quantity of blood flow in the main portal vein (Q_(pv)) were detected between bilateral subgroup and other 2 subgroups and control group (P<0.05). No statistical difference of diameter of right portal vein (D_(rpv)) and quantity of blood flow in the right portal vein (Q_(rpv)) was found among all groups and subgroups. The velocity of the right portal vein (V_(rpv)) of bilateral subgroup was statistically different with that of the control group and the simple thickening subgroup (P<0.05). No statistical difference of Q_(rpv)/Q_(pv) existed between the patients with liver cirrhosis and the normal subjects (P>0.05). 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.
