摘要
目的探讨彩色多普勒血流显像技术(CDFI)监测对肝移植术后门静脉并发症的诊断价值。方法应用CDFI对504例原位肝移植患者进行术前和术后连续监测。术前监测内容包括门静脉主干直径、血流速度及有无门静脉栓塞等;术后监测内容包括门静脉供体段,受体段、吻合口的直径、管腔内回声、血流方向及血流速度等。结果术后当日门静脉平均血流速度为46．27 cm／s,最小流速为15．8 cm／s,最大流速为110．8 cm／s。358例(71．03％)血流速度>40 cm／s。30 d后,347例(68．85％)流速降至40 cm／s以下。64例(12．70％)出现离肝血流,1例(0．20％)出现完全离肝血流。门静脉并发症13例(2．58％),包括4例(0．79％)栓塞(3例血栓、1例瘤栓),9例(1．79％)吻合口周围狭窄。结论异常门静脉血流信号不一定均出现并发症,连续动态观察门静脉血流的变化更有价值,因此,CDFI技术对监测肝移植术后门静脉并发症的诊断具有重要作用。
Objective To explore the diagnostic value of color Doppler flow imaging （CDFI） in monitoring portal vein complications （PVC） following orthotopic liver transplantation （OLT）. Methods Five hundred and four patients received OLT and had CDFI examinations before and after their translplantations. CDFI monitoring parameters before the operation included portal vein diameter, blood flow velocity and the presence of thrombi within the portal vein. Monitoring parameters after the operation included portal vein diameters of donor and receiver sides, and the diameter of the mouth of anastomosis, inner side of blood vessel echo, the direction of blood flow and its speed. Results Of the 504 patients examined, the median velocity of the portal blood flow was 46.27 cm/s （range： 15.8 to 110.8） on the day of the operation. The blood flow speed of 358 cases （71.03%） was higher than 40cm/s. Of the 358 patients, 347 （68.85%） had a blood flow speed lower than 40cm/s one month after the operation. Sixty-four patients （12.70%） showed hepatofugat blood flow once, and only one case had a total hepatofugat blood flow. Thirteen patients （2.58%） had portal vein complications, including 4 cases with portal vein thrombosis and 9 with portal vein stenosis. Conclusion Not all abnormal portal vein blood flow signals will lead to complications. It is worthwhile to monitor the portal blood flows. CDFI plays an important role in the diagnosis of portal vein complications after orthotopic liver transplantation.
