目的 了解血吸虫病洲岛型疫区居民血吸虫病病情 ,探讨 B超在评估血吸虫病病情中的应用价值。方法 在江西省鄱阳湖区某血吸虫病疫区 ,对该村 439名 3～ 6 0岁居民进行病原学检查和 B超检查。结果 粪检感染率为 2 9.2 9% ,男女差别无显著性。肝实质 级以上比例男性为2 7.1% ,女性为 17.4% ;门静脉内径异常比例男性为 15 .8% ,女性为 2 .1% ;脾静脉内径异常比例男性为 2 6 .1% ,女性为 36 %。多项 B超指标异常比例随年龄增加而升高。结论 B超检查能直接评价血吸虫病引起的肝脾损伤。
Objective To understand the prevalence of schistosomiasis among schistosomiasis in Chau Island-type endemic areas and to explore the value of B-ultrasonography in assessing schistosomiasis. Methods In a schistosomiasis endemic area of Poyang Lake in Jiangxi Province, 439 residents aged 3 ~ 60 were enrolled in the etiological examination and B ultrasound examination. Results The fecal infection rate was 2 9.29%, no significant difference between men and women. The proportion of men above the parenchymal level was 21.1% for males and 17.4% for females; the abnormal proportion of portal vein was 15.8% for males and 2.1% for females; the abnormal proportion of splenic vein was 26.1% for males and 36 %. A number of abnormal B-index anomalies increased with age. Conclusion B-ultrasound can directly evaluate the liver-spleen injury caused by schistosomiasis.
