摘要
目的探讨特发性门静脉高压症(IPH)的声像图特征,评价彩色多普勒对IPH的临床诊断价值。方法对25例IPH患者进行彩色多普勒超声检查,观察肝脏表面、内部回声、脾脏大小及肝内外门静脉系统等。结果25例患者中,25例均见门静脉肝内分支管壁增厚、回声增强、管腔狭窄甚至闭塞,15例实质回声增粗,门静脉海绵样变性22例,门静脉系统血栓5例,均为门静脉主干、脾静脉及肠系膜上静脉血栓,15例伴有胆道系统的异常。结论临床上不明原因的门脉高压及脾功能亢进患者均应进行彩色多普勒超声检查,肝内门静脉分支管壁增厚、管腔狭窄甚至闭塞的特征性改变及门静脉海绵样变性可提示IPH。
Objective To explore the characteristics of idiopathic portal hypertension （IPH） on color Doppler images and to assess the diagnostic value of color Doppler on IPH. Methods Color Doppler sonography was performed to assess the surface and interior echoes of liver, the size of spleen and portal vein system in twenty - five IPH patients. Results In 25 patients undergoing color Doppler examination , intrahepatic portal vein appeared thickened wall, enhanced echoes, stenosis or occlusion in all cases, and coarse liver parenchyma was found in 15 cases, portal vein system cavernous transformation in 22 cases, thrombosis in portal vein system in 5 cases which involved main portal vein, splenic vein and superior mesenteric vein. Fifteen patients had detectable biliary tract pathology by ultrasound examination. Conclusion Color Doppler plays an important role in the diagnosis of IPH. In clinical practice, patients with portal hypertension and hypersplenisa for unknown aetiology should receive color Doppler examination. As thickened enhanced wall, stenosis or occlusion of intrahepatic portal vein and cavernous transformation were appeared, the diagonsis of IPH would be suggested.
