摘要
目的探讨彩色多普勒超声判断肝硬化门静脉高压症(PHT)侧支循环形成情况在PHT临床分型及术式选择中的意义。方法对40例不同Child分级PHT患者(有食管胃底静脉曲张者28例),应用彩色多普勒超声检测门静脉血流方向及侧支循环形成情况。结果40例中向肝血流者30例(75%),双向血流者6例(15%),离肝血流者4例(10%)。自发性侧支循环形成27例(67.5%)。ChildA、B、C级侧支循环形成比例分别为11/20、6/8、10/12,差异无显著性(P>0.05)。食管胃底静脉曲张组侧支循环形成率为78.6%(22/28),无静脉曲张组侧支循环形成率为41.7%(5/12),二者之间差异有显著性(P<0.05)。结论彩色多普勒超声是观察肝门静脉血流量的良好方法,根据其判断侧支循环形成情况对PHT的临床分型和根据其分型选择不同手术方式具有重要意义。
Objective ： To investigate the collateral formation in portal hypertension patients by color Doppler ultrasound and study its significance in PHI classification. Methods ： 40 cases of patients with portal hypertension including 28 cases with esophageal varices, were studied portal vein flow direction, ascites, and collateral formation by color Doppler untrosound, compared with 20 healthy controls. Results ： In 40 cases, 30（75 % ）cases had prograde portal flow, 6 cases （15%） had hi-direction portal flow, and 4 cases （10%） had hepatofugal portal flow. Spontaneous collaters were formed in 27 cases . collateral formations were found in 11 cases from 20 Child A,6 cases from 8 Child B and 10 cases from 12 Child C . The difference was no statistical significance （ P 〉0.05）. There was a significant difference of collateral formation between esophageal varices group and none varices group（78. 6% vs 41.7%）. Conclusion： Color Doppler ultrasound is a good method in the measurement of portal blood flow. It plays an impartant role in the dinical classification and operation approaehe selection of portal hypertension patients by determining the collateral formation.
