目的探讨多层螺旋CT静脉成像在诊断肝硬化门静脉高压症方面的应用价值。方法选取2011年3月~2013年6月在湖南省邵阳县人民医院接受腹上区多层螺旋CT静脉成像检查的35例受检者作为研究对象,对受检者均采用GE Hispeed双排螺旋CT行CT扫描检查,根据病理证实分为健康对照组(n=12),代偿期肝硬化组(n=9),失代偿期肝硬化组(n=14),比较3组门静脉宽度(PV)、肝右静脉宽度(RHV)、PV/RHV及血管分支参数。结果正常组PV比代偿期肝硬化组及失代偿期肝硬化组小,差异均有统计学意义(均P<0.05);代偿期肝硬化组RHV比正常组及失代偿期肝硬化组大,差异均有统计学意义(均P<0.05);失代偿期肝硬化组PV/RHV比正常组及代偿期肝硬化组大,差异均有统计学意义(均P<0.05);正常组、代偿期肝硬化组及失代偿期肝硬化组在PV分支显示和RHV分支显示方面比较差异均有统计学意义(均P<0.05)。结论采用多层螺旋CT静脉成像能够准确测量门静脉宽度及肝右静脉宽度,清晰显示血管分支,在诊断肝硬化门静脉高压症方面具有很高的应用价值。
Objective To investigate the value of multislice CT venography in the diagnosis of portal hypertension in patients with cirrhosis. Methods From March 2011 to June 2013, 35 subjects who underwent multi-slice spiral CT venography in the abdominal region of Shaoyang County People’s Hospital of Hunan Province were selected as study subjects. All the subjects were treated with GE Hispeed double helix According to the pathological findings, CT scan was divided into healthy control group (n = 12), decompensated cirrhosis group (n = 9) and decompensated cirrhosis group (n = 14) (PV), right hepatic vein width (RHV), PV / RHV and vessel branch parameters. Results PV in normal group was smaller than that in decompensated cirrhosis group and decompensated cirrhosis group (all P <0.05). Compared with normal group and decompensated cirrhosis group, RHV in decompensated cirrhosis group (P <0.05). The PV / RHV in decompensated cirrhosis group was significantly higher than that in normal group and decompensated cirrhotic group (all P <0.05), and the differences were statistically significant ). There were significant differences in PV branch display and RHV branch display between normal group, compensated cirrhosis group and decompensated cirrhosis group (all P <0.05). Conclusions Multi-slice spiral CT venography can accurately measure the width of portal vein and the width of right hepatic vein, and clearly show the branches of blood vessels. It is of great value in diagnosing cirrhosis and portal hypertension.
