Patients who had portacaval shunts were examined both before and after surgery. In the majority of cases, it was possible to detect the portcaval shunt by actually demonstrating the site of anastomosis. There was dilatation of the vena cava just cephalad to the site of the anastomosis due to the increased volume of blood entering the vena from the portal system. Mesocaval shunts have also been detected. Splenorenal shunts, however, could not be demonstrated in this series. While gray scale B scan ultrasound was used to record the site of anastomosis and measure the vessel diameters, real time two-dimensional ultrasound provided dynamic information. Long term serial examination are being obtained to evaluate the continued patency of the shunts. Ultrasound appears to be a promising new noninvasive study for the evaluation of portcaval shunts.
接受门腔分流术的患者在手术前后均接受了检查。在大多数情况下，通过实际显示吻合部位可以检测到门腔分流。由于从门静脉系统进入腔静脉的血量增加，吻合部位上方的腔静脉出现扩张。也检测到了肠系膜上腔静脉分流。然而，在本系列中未能显示脾肾分流。虽然使用灰阶B超扫描记录吻合部位并测量血管直径，但实时二维超声提供了动态信息。正在进行长期系列检查以评估分流的持续通畅情况。超声似乎是一种很有前景的用于评估门腔分流的新型无创检查方法。
