肝炎后肝硬化胃底静脉曲张超声与胃镜检查对比评价

目的 探讨经腹彩色多普勒超声诊断胃底静脉曲张的应用价值.方法 使用彩色多普勒超声及电子胃镜检查46例肝炎后肝硬化胃底静脉曲张患者,观察粘膜层血流情况及测量曲张静脉直径,并与胃镜进行对照分析.结果 46例胃底静脉曲张患者,40例同时并存食管静脉曲张,6例为孤立性胃底静脉曲张.二维灰阶超声显示胃底部粘膜层增厚,彩色多普勒可在增厚的粘膜层内检测到血流信号,并显示血管的形态特征.超声测量曲张静脉直径与胃镜检查结果呈正相关,相关系数分别为：轻度r=0.61,中度r=0.78,重度r=0.91.结论 经腹彩色多普勒超声可诊断胃底静脉曲张,并能进行比较准确的分度,具有较高的临床实用价值.

Comparative assessement of value of ultrasonography and gastroscopy in diagnosis of gastric fundal varies of hepatic Liver cirrhosis

Objective To assess the value of ultrasonography and gastroscopy in diagnosis of gastric dundal varices in cirrhosis of hepatitis patients.Methods There 46 cirrhosis cases with gastric fundal carices were examined wtj color Doppler flow image and telegastroscopy.The diameter of vein was measured and blood flow signal was determined.Results There fundal varices and esophageal varices were observed in 40 cases.Single fundal varices was observed in 6 cases.Two dimentional curve showed that there was thickened mucosa.Blood flow signal in thickened mucosa was detected and the shape of blood vessels was dispayed.The diameter of vein detected by ultrasonography is positively correlated with that of gastroscopy(with the correlation coefficient of small,intermediate and large sizes of r=0.61,r=0.78 and r=0.91,respectively).Conclusion Transabdominal clolor Doppler flow image is valuable for diagnosis of fundal varicosis.
