...压组及对照组肝动脉、门静脉血流的有关参数：即空腹状态下门静脉、肝动脉血流速度及肝动脉搏动指数(HAPI)、肝动脉阻力指数(HARI)，并以试餐方式改变门脉血流速度，观察肝动脉血流速度相应的变化，比较肝动脉试餐前后血流速度相对差值，以了解彩超有关参数在反...

方法选用高频手术专用探头，于手术中门静脉、肝动脉吻合完成后立即测量肝动脉及门静脉血流速度，并计算快速充盈时间及阻力指数。
Methods Liver scanning was performed with a high frequency transducer to measure the velocity acceleration time and resistant index of portal vein and hepatic artery after finishing the anastomosis.
超声观察肝外胆管内径、管壁厚度、管腔内透声、肝动脉峰值流速(PS V)、阻力指数(RI)。
Focus on extrahepatic bile duct diameter, wall thickness, lumen transparent sound, hepatic artery peak flow velocity (PSV) and resistance index (RI).
结论肝移植术后低阻力指数与早期肝动脉并发症有明显相关性，而高阻力指数和舒张期无血流与肝动脉并发症无明显相关。
Conclusion Lower RI after liver transplantation is obviously relevant to hepatic artery complications, while higher RI and no blood flow in diastole is not obviously relevant.
