经膈门-体侧支循环的影像学表现及临床意义

目的:进一步了解横膈的静脉引流及其在门静脉高压和下腔静脉阻塞时的侧支循环,心包膈静脉曲张及纵隔其他侧支旁路的影像学表现及临床意义。方法:查阅国内外有关经膈门—体侧支循环的影像学文献,并加以总结。结果:经膈门—体侧支循环并不罕见,应常规包括在纵隔及纵隔旁占位性病变的鉴别诊断中。结论:影像学检查尤其是CT检查在经膈门—体侧支循环的诊断及鉴别诊断中具有重要意义。

Imaging Findings and Clinical Significance of Transdiaphragmatic Portosystemic Shunt

Objective:To further understand diaphragmatic venous drainage and shunt in patients with portal hypertension and inferior vena cava obstruction,imagingf indings and clinical significance of the pericardiacophrenic vein and mediastinal collateral veins.Methods:Inquiring and summarizing literatures about the pericardiacophrenic vein and mediastinal collateral veins.Results:transdiaphragmatic portosystemic shunt was not unusual,It should be included in the differential diagnosis of mediastinal and paramediastinal diseases.Conclusions:Imaging examination,particularly CT plays a significant role in diagnosis and differential diagnosis of transdiaphragmatic portosystemic shunt.
