Seventy-one children with portal hypertension and a portocaval anastomosis were studied by ultrasound. The patency of the shunt may be inferred when it directly visualised. There are four indirect signs of patency: (1) decrease of the thickness of the lesser omentum; (2) decrease of the gastro-oesophageal collaterals; (3) decrease of the portal vein size; and (4) increase of the diameter of the inferior vena cava, as compared to pre-operative ultrasound.
对71例患有门静脉高压并接受门腔静脉吻合术的儿童进行了超声检查。当分流直接可视化时，可以推断分流的通畅情况。有四个通畅的间接征象：（1）小网膜厚度减小；（2）胃食管侧支减少；（3）门静脉尺寸减小；（4）与术前超声相比，下腔静脉直径增加。
