| 摘 要： | 本文通过对３５例门脉高压并食管静脉曲张病人的彩色多普勒超声显像（ＣＤＦＩ）研究，并与３０例对照组比较，探讨经内窥镜食管静脉结扎术前后，门、奇静脉侧枝循环血流动力学变化的ＣＤＦＩ表现。ＣＤ－ＦＩ检查证实食管曲张静脉结扎术不仅消除粘膜下曲张的食管静脉，而且部分阻断侧枝循环，使胃和肝脏的血流增加。

| Abstract: | Color Doppler flow imaging(CDFI) was performed in 35 patients with portal hypertension and esophageal varix. Thirty subjects were served as control. After esophageal variceal ligation, CDFI observed that the portal superior vena cava collateral veins were partialy blocked. The esophageal varices disappeared. The esophageal wall thinned. Diameter of left gastric vein enlarged and blood flow velocity decreased. Azygos diameter was reduced and blood flow velocity was decreased. Although diameter of portal vein was not changed, the blood flow velocity slightly increased. The results suggest that ligation treatment can have the tendency to increase blood flow of liver and stomach, which might aggravate gastric mucosal lesion. |
