Using a convex array transducer, the advantages and shortcomings of transesophageal real-time two-dimensional Doppler echography (TE2DD) were assessed in a study of the vessels around the esophagus and the stomach in 67 adult patients with (n = 56) or without (n = 11) liver cirrhosis. In most cases, all but the upper- and lowermost margins of the azygos vein could be visualized. The more caudally the portion located, the smaller its diameter and flow velocity became. The average number of intercostal veins visualized by TE2DD was 4 per person. The observable esophagogastric varices seemed to be limited to deeply located ones around the esophagogastric junction. In five patients who had undergone distal splenorenal shunt, splenic venous flow, or shunt flow could be seen from the stomach over a length of about 5 cm. The azygos venous flow in cirrhotic patients was significantly greater than that of patients without cirrhosis. TE2DD appears to be very useful for evaluating flow in the cephalad collateral veins and other vessels around the esophagus and the stomach.
采用凸阵探头，在67例有（n = 56）或无（n = 11）肝硬化的成年患者中，对食管和胃周围血管进行研究，评估经食管实时二维多普勒超声检查（TE2DD）的优缺点。在大多数情况下，除奇静脉的最上和最下边缘外，其余部分均可显示。位置越靠尾端，其直径和流速越小。TE2DD观察到的肋间静脉平均每人4条。可见的食管胃静脉曲张似乎仅限于食管胃交界处周围较深部位的曲张静脉。在5例接受远端脾肾分流术的患者中，可在胃内约5 cm的长度范围内看到脾静脉血流或分流血流。肝硬化患者的奇静脉血流明显大于无肝硬化患者。TE2DD似乎对评估食管和胃周围头侧侧支静脉及其他血管的血流非常有用。
