Ultrasonography can reveal most of the manifestations of portal hypertension complicating hepatosplenic schistosomiasis. However, direct demonstration of gastroesophageal varices by ultrasonography is still very difficult. An attempt was done to correlate sonographic features of portal hypertension with the degree of fibrosis to screen patients having varices and predicting their chance of bleeding. The results obtained were found to be consistent with the esophagogastric endoscopy and with history of hematemesis. Four parameters were used, size of spleen, degree of periportal fibrosis, presence of collaterals and portal vein diameter. A pilot field survey was also done adopting the same principle.
超声检查可显示肝脾型血吸虫病并发门静脉高压的大多数表现。然而，通过超声直接显示胃食管静脉曲张仍然非常困难。本研究试图将门静脉高压的超声特征与纤维化程度相关联，以筛查有静脉曲张的患者并预测其出血几率。研究结果与食管胃内镜检查结果及呕血病史相符。采用了四个参数，即脾脏大小、门静脉周围纤维化程度、侧支循环的存在情况和门静脉直径。还按照相同原则进行了一项试点现场调查。
