为研究食管静脉曲张与门静脉分流的关系，采用核素技术９９ｍ锝－甲氧异腈经单光子发射计算机断层扫描仪检测门－体分流程度。结果其心肝比值（Ｈ／Ｌ）对照组为０．１９９±０．１３６，肝硬化组为０．７８０±０．２００，Ｐ＜０．０１；分流率（ＳＩ）对照组为０．１８０±０．０７７，肝硬化组为０．４２０±０．０６３，Ｐ＜０．０１。３７例行胃镜检查的肝硬化患者的Ｈ／Ｌ、ＳＩ值与食管曲张静脉条数正相关，其相关系数Ｈ／Ｌ为ｒ＝０．６９７，Ｐ＜０．０５；ＳＩ为ｒ＝０．７２４，Ｐ＜０．０１。Ｈ／Ｌ、ＳＩ的均值按曲张静脉条数分组，１～２条组与≥３条组比较，差异有非常显著性意义，Ｐ＜０．０１；以食管静脉曲张程度分组，其Ｆ０、１与Ｆ２、３组组间差异显著，Ｐ＜０．０５；蓝色静脉曲张伴红色征与不伴红色征组比较Ｐ＜０．０１。出血组与未出血组比较，前者Ｈ／Ｌ、ＳＩ均值明显高于后组，Ｐ＜０．０５。研究认为核素门腔分流显像，其Ｈ／Ｌ、ＳＩ值可反映门－体分流程度、食管静脉曲张程度与门腔分流率的关系。
In order to study the relationship between esophageal varices and portal vein shunt, 99m technetium-methoxyisonitrile was used to detect the degree of portal-to-body shunt by single-photon emission computed tomography. Results The heart-liver ratio (H / L) was 0.199 ± 0.136 in the control group and 0.780 ± 0.200 in the cirrhosis group, P <0.01; the SI group was 0.180 ± 0.077, cirrhosis group was 0.420 ± 0.063, P <0.01.37 The correlation between H / L, SI and the number of esophageal varices in cirrhotic patients with gastroscopy was statistically significant H / L was r = 0.697, P <0.05; SI was r = 0.724, P <0.01. The mean values of H / L and SI were grouped according to the number of varicocele. The difference between groups 1 and 2 and ≥3 was significant (P <0.01) And F2,3 group, the difference was significant, P <0.05; blue varicose veins with red signs compared with non-red sign group P <0.01. Bleeding group and non-bleeding group, the former H / L, SI was significantly higher than the latter group, P <0.05. The study suggests that the radionuclide portosystemic shunt imaging, the H / L, SI value can reflect the degree of portal-body shunt, the degree of esophageal varices and the relationship between the rate of portal shunt.
