CE-MRA在腹部静脉病变中的应用及诊断价值

The applicable and clinical value of contrast enhanced MR angiography in the abdominal veins diseases

目的探讨腹部静脉病变的CE-MRA的表现及临床应用价值。方法回顾性分析47例腹部静脉病变的常规MRI和腹部静脉CE-MRA表现。结果门脉高压28例(肝硬化性22例,非肝硬化性6例),其中1例合并静脉瘤;静脉内瘤栓8例;肿瘤性静脉包绕4例;布-加氏综合征(Budd-chiarrisyndrome,BCS)2例,门静脉海绵状变性(非肿瘤性)2例,肝移植术后3例。CE-MRA清楚显示了门静脉、脾静脉、胃冠状静脉的增粗,食道胃底静脉的曲张;瘤栓所致的腔内低信号区;静脉被肿物推移受压的情况;门静脉、肝静脉、下腔静脉的狭窄、闭塞和侧枝循环的分布范围和程度。常规MRI显示了腹部脏器的原发病变。结论CE-MRA结合常规MRI检查对腹部静脉病变有一定的诊断价值,对临床治疗方案的选择有明确的指导意义。

Objective：To evaluate the applicable and clinical value of CE-MRA and MRI in the abdominal veins＇ diseases. Methods： 45 cases with abdominal diseases were examined by conventional MRI（cMRI） and contrast enhanced MR angiography in abdominal veins. Results：45 cases were as follows： portal hypertension （ n = 28）, venous carcinomatous thrombosis （ n = 8）, veins revolved by malignant tumer（ n = 4）, Budd-chiarri syndrome（ n = 2 ）, spongy portal vein（ n = 2 ）, follow-up after liver transplantation（ n = 3 ）. The enlarged portal veins and spleen veins as well as esophageal-gastric variees were dearly showed on CE-MRA. The MRA distinctly demonstrated the venous carcinomatous thrombosis, veins revolved by malignant tumor, nan＇owing and occlusion of portal/hepatic veins and inferior vena cava. cMRI displayed the primary diseases in the abdominal organs. Conclusion. CE-MRA and are useful and valuable technigue in the abdominal veins diseases. It is helpful for therapy.
