The risk of variceal bleeding (VB) in patients with cirrhosis and esophageal varices may be determined by the portal pressure gradient. The value of Color Duplex Doppler Ultrasonography (CDDU) in the identification of patients at risk for variceal bleeding has been discussed in the literature. In patients with esophageal varices at risk for bleeding, CDDU did not detect patients who presented variceal bleeding during a mean follow-up of 7 months. However, patients with a low Congestion Index (< 0.05) and a mean upper portal vein velocity of > 9 were at lower risk for variceal bleeding. The Congestion Index was higher in patients with bleeding during the follow-up (0.09 vs. 0.057 (p = 0.03) and the mean portal vein velocity was lower in these patients (10.7 vs. 14).
肝硬化合并食管静脉曲张患者发生静脉曲张破裂出血（VB）的风险可能由门静脉压力梯度决定。彩色双功多普勒超声检查（CDDU）在识别静脉曲张破裂出血风险患者中的价值已在文献中进行了讨论。在有出血风险的食管静脉曲张患者中，在平均7个月的随访期间，CDDU未检测出发生静脉曲张破裂出血的患者。然而，充血指数低（<0.05）且门静脉平均流速>9的患者发生静脉曲张破裂出血的风险较低。随访期间出血患者的充血指数较高（0.09对0.057，p=0.03），这些患者的门静脉平均流速较低（10.7对14）。
