螺旋CT对区域性门静脉高压的诊断及临床价值

Diagnostic Value and Clinical Significance of Multi-slice CT in Regional Portal Hypertension

目的:探讨多层螺旋CT(MSCT)对区域性门静脉高压(RPH)的诊断及临床指导价值。方法:对21例区域性门静脉高压患者使用6排多层螺旋CT机行上下腹部CT增强扫描,分析脾静脉闭塞后侧支循环开放及曲张情况。结果:脾静脉局部突然中断、明显狭窄或不显影12例,主要的两个侧支循环通道有胃短静脉-胃底静脉丛-胃冠状静脉和胃网膜静脉-胃结肠干-肠系膜上静脉,在螺旋CT上表现出特征性的分布和走行。结论:MSCT增强多排螺旋CT能清晰显示RPH患者脾静脉闭塞后侧支循环开放及曲张情况,对于RPH的诊断和指导临床治疗具有重要的价值。

Objective：To investigate the value of multi- slice CT（MSCT） in clinical significance and imaging diagnosis of regional portal hypertension （ RPH ）. Methods ： A 6 - detector row spiral CT scanner was used to perform contrast enhanced abdominal scanning in 21 patients with RPH. Analysed splenic vein occlusion and collateral vessels opeuned varicose condition. Results：Splenic vein showed oeelusioned or interrupted in 12 eases. The two predominant collateral pathways of RPH were：short gastric veins -fundic veins-gastric coronary vein and gastroepiploie veins-gastrocolonic trunk-superior mesenteric vein. These collateral veins usually showed characteristic anatomic distributions and pathways on spiral CT. Conclusion：In patients with RPH, MSCT is very effective for displaying the splenic vein occlusion and collateral vessels open varicose condition , which is very significant in clinical practice.
