摘要
【目的】通过对门静脉高压病人门静脉系统及其侧支循环的CT扫描,研究相关指标在预测胃底、食管静脉曲张破裂出血的敏感度、特异度以及可能预测出血的临界点。【方法】CT对门脉高压患者分组(出血组与未出血组)观察测量胃冠状静脉(vena coronaria ventriculi)直径、胃底-脾门区域内血管断面数量和总面积。计算以上指标在门静脉高压上消化道出血预测诊断中的敏感度(sensitivity)、特异度(specificity),预测出血的临界点(cut-off points)以及约登指数(Yonden value)。【结果】胃冠状静脉直径,脾门-胃底区域血管断面数量、脾门-胃底区域血管断面总面积等指标在门脉高压致上消化道出血组和未出血组之间差异有显著性,在预测出血时其敏感度、特异度以及约登指数有差异。【结论】胃冠状静脉直径,脾门-胃底区域血管断面数量、脾门-胃底区域血管断面总面积可以作为CT预测肝硬化门静脉高压可能合并上消化道出血的指标,其中脾门-胃底区域血管断面总面积作为一种新的CT检测指标具有较高的预测诊断价值。
[Objective]To observe and measure portal vein and varicose vein in esophagus and gastric fundus of the portal hypertension by CT, try to find a marker to predict the upper gastrointestinal hemorrhage. [Methods]The portal hypertension patients were divided into two groups , one group had the upper gastrointestinal hemorrhage, another had not. Their livers were observed by CT, measured the diameter of vena coronaria ventriculi, calculated the number of blood vessels and total area of these vessels in fundus of stomach,hilum of spleen region. The sensitivity, specificity,cut-off points, Yonden value of the test were got to predict the upper gastrointestinal hemorrhage. [Results]Surface of all livers was uneven, splenomegaly, lateral branch circulation of portal vein opened. The diameter of vena coronaria ventriculi, the number of blood vessels and total area of these vessels in fundus of stomach, hilum of spleen region had significant difference between the two groups. [Conclusion]The diameter of vena coronaria ventriculi, the number of blood vessels and total cross section area of these vessels in fundus of stomach,hilum＇ of spleen region can predict the upper gastrointestinal hemorrhage caused by portal hypertension with cirrhosis of liver. The total cross section area of these vessels in fundus of stomach,hilum of spleen region has predictable diagnostic value.
