门静脉系统海绵样变性的超声诊断

Diagnosis of Cavernous Transformation of the Portal Vein System

目的探讨门静脉系统海绵样变性的超声显像特点。方法总结分析11例经血管造影证实的门静脉系统海绵样变性的超声表现。结果超声诊断符合率100%。二维超声病变区域表现为蜂窝状无回声暗区,CFI表现为暗淡血流充盈无回声暗区。结论超声可以显示门静脉系统及其属支的走行状态、血流充盈状态,便捷、无创、价廉,优于其他影像学方法。

Objective To explore the ultrasound image characteristics of cavernous transformation of portal vein system. Methotis Eleven cases with cavernous transformation of portal vein system were reviewed about the ultrasound image, all those were examined and proved by DSA. Results The ultrasound diagnostic rate is 100%. 2-D ultrasound showed network topology, CFI showed the network topology were filled with low speed vein blood flow. Conclusion Color Doppler ultrasonography demonstrates the anatomy and blood flow of portal vein system. It is convenient, noninvasive and cheap, and it is a better diagnostic method than the other radiology methods.
