【摘要】 超声检查因其独有的优势成为胆道闭锁的首选检查方法。随着超声医生逐渐专业化和技术设备水平的提高,超声检查对胆道闭锁患儿的观察更趋细化,不断有学者就此展开研究并提出不同的异常影像改变。胆道闭锁在产前超声中能够显示的异常影像改变主要包括囊性胆道闭锁和胆囊不可探及等。产后超声诊断胆道闭锁应对多种影像学表现综合分析,包括胆囊是否存在,胆囊大小、形态、壁的改变,进食后胆囊收缩状态,三角征,肝被膜下血流及肝动脉扩张等表现。就胆道闭锁在产前、产后异常的超声表现及其诊断价值的研究进展作一综述。更多还原

【Abstract】 Ultrasound is the first choice for biliary atresia due to its unique advantages. With the increasing professionalization of ultrasound doctors and the improvement of technical equipment, ultrasound observation of children with biliary atresia has become more and more detailed, and scholars have continued to study on this and proposed different abnormal image changes. The abnormal image changes that biliary atresia can show in prenatal ultrasound include cystic biliary atresia and non-visualization of gallbladder.Ultrasound diagnosis of postnatal biliary atresia should comprehensively analyze multiple imaging manifestations, including the presence of the gallbladder, changes in the size, shape, and wall of the gallbladder, gallbladder contraction status after eating, triangle signs, subcapsular blood flow, and hepatic artery dilatation. This article reviews the advances in ultrasound findings and diagnostic value of biliary atresia before and after birth.更多还原
