核素脾门静脉显像对门脉高压侧支循环的诊断及意义

Diagnosis of collateral vein circulation portal hypertension with splenoportoscintigraphy

目的 :探讨肝硬化门脉高压所致侧支循环的影像学特点和临床意义。方法 :以无肝硬化患者10例为对照 ,对 5 0例肝硬化门脉高压患者进行了核素脾门静脉显像。结果 :5 0例肝硬化患者中 37例显示有粗大清晰的侧支血管 ,另 13例虽未清楚显示侧支循环 ,但脾门轴静脉及心肝显影时相、脾门轴静脉形态均明显异常。结论 :脾门静脉显像是诊断门脉高压所致侧支循环异常血流动力学有价值的方法 ,值得临床推广应用。

Objective:To investigate the characteristics and clinical singnificance of nuclide image of collateral vein in portal hypertension. Methods: In contrast to 10 non cirrhotic volunteers, 50 cirrhotic patients with portal hypertension went through splenoportoscintigraphy. Results: 37 cases of 50 patients showed thick,clear collateral blood veins. Although the other 13 cases did not show clear collateral veins, the time of splenoportal circulation, the heart and liver images, and splenoportal circulation shape were all distinctively abnormal. Conclusions: Being a valuable technique in the diagnosis of abnormal blood circulation dynamics of the collateral vein caused by portal hypertension, splenoportoscintigraphy is well worth clinical popularization and application.
