ABSTRACT
Objective To investigate the relationship between CT signs of portal hypertension and histopathologic stage of chronic hepatic fibrosis and cirrhosis. Methods Tri-stage enhance volume CT scan of upper abdomen was performed in 84 participants, including 48 patients with hepatic fibrosis confirmed by liver pathologic biopsy which divided into S1 (12/48), S2 (14/48), S3 (9/48) and S4 (13/48),16 patients with typical cirrhosis, and 20 healthy subjects as a control group. Measured the caliber of left and right branch of portal vein, MPV, SV and SMV at MIP images respectively, observed the collateral circulation, ascites and the size of spleen and then studied comparatively these measured parameters of different histopathologic stage. One-Way ANOVA was performed in the comparison of the vascular diameter of portal system and the size of spleen(SNK was used in the comparison between the groups). x2 test ofR × Ctable was performed in the comparison of ascites and collateral circulation among groups, and the vessel of portal system which has the greatest impact on the pathological staging of hepatic fibrosis was investigated with Logistic regression analysis. Results The caliber of left branch of portal vein, right branch of portal vein. MPV. SV and SMV were (0.98±0.11). (1.00±0.12), (1.33±0.11). (0.75±0.10).(1.07±0. 12) em respctively, the size of spleen was (128. 55±30. 56) cm<'3>, and collateral circulation and ascites were not found in control group. SV enlarged gradually in test groups and showed S1 (0. 86±0. 12) cm, S2(0. 96±0. 11) cm, S3(1.07±0.08) cm, S4(1.09±0. 10) cm, typical cirrhosis (1.18±0. 19) cm respotively. The difference between each group of S1 to typical cirrhosis and control group was significant, and the same result was seen among S3 to S4, cirrhosis and S1 to S2. Logostic regression analysis showed that the standardized regression coefficient of SV was maximum (2. 719) and had statistical significance(P <0. 01). The incidence of collateral circulati on and ascites in patients with typical cirrhosiswas significant higher than that of normal liver and every stage of hepatic fibrosis (P < 0. 05). Conclusion CT scan may be helpful for the early detection of advanced hepatic fibrosis or early stage of liver cirrhosis for patients with chronic liver disease.
