69例门静脉高压患者在三维动态增强磁共振血管成像显示侧支循环分布的分析

目的探讨三维动态增强MR血管成像所显示门静脉高压患者侧支循环的分布情况。方法选取我院检查的69例门静脉高压患者，并进行门静脉系统的3DDCEMRA检查，对减影后的影像学资料及MIP重建图像进行分析，统计侧支循环的分布情况。结果69例门静脉高压患者中，食管和食管周围静脉曲张45例，胃底静脉曲张47例，奇／半奇静脉曲张35例；胃左静脉曲张34例，胃后静脉曲张11例，胃-肾分流13例；脾周静脉曲张14例，脾-肾分流者4例；附脐静脉曲张21例；性腺静脉曲张17例。结论3DDCEMRA不仅能发现门静脉高压患者的曲张的侧支循环，还可以明确血管起止、走行和毗邻关系。

Analysis of 3D-DCE-MRA for displaying collateral circulation in 69 patients suffering portal hypertension

Objective To explore the distributions of the collateral circulation in portal hypertension patients displayed by 3D-DCE-MRA. Methods 69 patients with portal hypertension who had undergone hepatic portal vein 3D-DCE-MRA in our department were selected. These image data were analyzed after subtracting and MIP reconstructing. Then added up the distribution of collateral circulation. Results Among the 69 cases, there were 45 cases with esophageal varix, 47cases with gastric fundus varix, 35 cases with azygos or hemiazygos varix, 34 cases with left gastric varix, 11 cases with posterior gastric varix, 13 cases with gastric renal shunt, 14 cases with renal varix, 4 cases with spleen renal shunt, 21 cases with paraumbilical veins rarix, and 17 cases with gonad varix. Conclusion 3D-DCE-MRA not only can discover the varix collateral circulation, but also is able to display the veins from origin to the end and the relations between the veins and their surrounding structure more clearly.
