亲体原位部分肝移植术后血流动力学的变化

目的 探讨亲体原位部分肝移植术后血流动力学的变化。方法 应用彩色多普勒血流显像仪检查10例正常人和7例亲体原位部分肝移植术前、后的肝血流动力学改变。结果 6例肝移植术后经过正常，门静脉、肝动脉、肝静脉的血流于术后1－5个月逐渐恢复正常。1例肝移植术后出现并发症。肝动脉血流速度低于28cm/s，血流呈扑动状，同时阻力指数增至0.78，提示肝动脉血栓形成。结论 彩色多普勒血流影像在肝移植术前、后可有效监测肝血流动力学变化，可早期发现一些致命的并发症，为临床早期处理提供准确依据，对保证肝移植成功有着重要的临床意义。

Changes of haemodynamics after relative orthotopic liver transplantation

To study the changes in haemodynamics of relative orthotopic liver transplantation. Methods The haemodynamical changes in 10 normal controls and 7 patients undergoing relative orthotopic liver transplantation before and after operation were examined by using color Doppler flow imaging (CDFI). Results The hemodynamic characteristics were regularly restored in 1-5 months after operation in 6 cases. The postoperative complications occurred in one case after liver transplantation. If the velocity of hepatic artery was less than 28 cm/s, blood flow fluttered and RI was increased to 0. 78, hepatic arterial thrombosis formed. Conclusions Hepatic haemodynamics can be monitored efficiently by CDFI before and after liver transplantation. The fatal complications can be discovered earlier. Color Doppler ultrasound is very useful for assuring the success of relative orthotopic liver transplantation.
