摘要
本文搜集连续100例正常成年男性、50例无明显侧支循坏血管的肝硬化门脉高压症(CPH)患者、50例伴有明显侧支循环血管的(CPH)患者,分别测量其门静脉主干(PV)宽径、肠系膜上动脉宽径(SMA)并计算PV/SMA的比值。经统计学分析,结果显示:正常成年男性的PV值为1.16±0.06cm,≤1.47cm;比值为1.72±0.27,≤2.25。当PC值≥1.87cm时,CPH在CT图像上常见有侧支循环血管。作者认为,本组测量结果可为CPH的CT诊断提供一项较实用的、客观的指标。
A series of consecutive male adults including one hundred normal adults, fifty cases with cirrhotic portal hypertension (CPH) without obvious gastroesophageal varices and another fifty cases of CPH with obvious gastroesophageal varices, are divided into the group A,B and C respectively. The diameter of the portal vein (PV) and the superior mesen-teric artery (SMA) were measured on CT film and the ratio of the diameter of PV to that of SMA were calculated in each case. The results showed that the normal average diameter of PV and the RATIO are 1.16±0.16cm, 1.72±0.27 and its maximum values are 1.47cm and 2.25 respectively. It is usually accompanied with the obvious gastroesophageal varices when the PV diameter is more than 1.87cm. We considered that the results can be taken as one of the useful and objective indexes to CT diagnosis of CPH.
