摘　　要：目的 :深入探讨超声对肝移植术后肝动脉并发症的诊断价值。方法 :通过回顾 16 0例原位肝移植患者的彩色多普勒血流 (CDFI)资料 ,对其中发生肝动脉血栓及狭窄的 39例患者的 (CDFI)资料进行总结并与螺旋 CT、血管造影对照。结果 :高贞频可提高肝动脉二维超声的显示率。 CDFI对肝动脉的显示率达 94 .5 % ,PW对吻合口狭窄的诊断率为 85 .3%。 S/ D对肝动脉并发症的敏感性极高。发生动脉并发症的患者 S/ D全部小于 2。结论Objective:To investigate the value in the diagnosis of postoperative hepatic artery complications in liver transplantation with ultrasonography thoroughly.Methods:The Color Doppler Flow Imaging(CDFI)data of 39 cases of hepatic arterial thrombus and stenosis was summarized and these data with spiral CT and angiography by summarizing the CDFI data of 160 cases of orthotopic liver transplantation.Results:High vibration frequency could increase the visualization rate of hepatic arteries with two dimensional ultrasonography.The visualization rate of hepatic arteries with CDFI amounted to 94 5%.The diagnostic accordance rate of stricture of the anastomotic stoma with PW amounted to 85 3%.The sensitivity of hepatic artery complications with S/D was extremely high.S/D of those patients with artery complications was less than 2.Conclusions:Ultrasonography provides a noninvasive and high sensitive method of examination and diagnosed hepatic artery complication.
