肝硬化门静脉高压症腹壁浅静脉腹部CT表现

Superficial collateral veins on abdominal CT in patients with cirrhosis and portal hypertension.

目的观察肝硬化门静脉高压患者腹壁浅静脉腹部CT的表现。方法30例经手术治疗的肝硬化门静脉高压患者作为肝硬化组,回顾术前的腹部CT片,计数前腹壁浅静脉数目,并测量肠系膜上静脉直径,术中测量门静脉压力;同时取30例非慢性肝病患者的腹部CT片作为对照,比较两组腹壁浅静脉在CT中的数目是否不同。结果肝硬化组腹壁浅静脉数目[(2.50±1.57)条]明显多于对照组[(1.40±0.89)条,P<0.01]。肝硬化组肠系膜上静脉增粗为(11.96±2.11)mm,门静脉压力平均(41.33±0.88)cmH2O。结论与正常人相比,肝硬化门静脉高压患者腹部CT检查腹壁浅静脉的数目明显增多,有助于门静脉高压的诊断。

Objective To observe the findings of superficial collateral veins on abdominal CT in patients with cirrhosis and portal hypertension. Methods 30 surgical patients with cirrhosis and portal hypertension were taken as cirrhosis group, whose abdominal CT was reviewed in order to determine abdominal superficial vein numbers in portal hypertension. Superior mesenterie vein diameter was measured and portal pressure was measured intraopera- tively. Meanwhile abdominal CT of 30 cases of non-chronic liver diseases was taken as controls. Results Abdominal superficial veins were significantly more in patients with cirrhosis than in the normal controls [ （ 2.50 ± 1.57 } vs. （ 1.40 ± 0.89 } , P 〈 0.01 ]. Superior mesenteric vein diameter was thickened （ 11.96 ± 2.11 } mm and portal pressure was higher （ 41.33 ± 0.88 ） cm H2O. Conclusion Superficial vein numbers in abdominal CT of portal hypertension and cirrhosis are significantly increased ,which will contribute to the diagnosis of portal hypertension.
