Abstract
目的 探讨彩色多普勒超声在肝移植术后发生肝动脉狭窄及其围介入治疗中的监测作用.方法 回顾性分析71例原位肝移植病人的超声检查资料,其中发生肝动脉狭窄并进行介入治疗的5例,并与同期血管造影对照.结果 发生肝动脉狭窄病人彩色多普勒血流显像(CDFI)可见肝动脉纤细迂曲,多呈间断性星点闪烁状;近狭窄处肝动脉血流峰速(S1)升高(163.62±14.66)cm/s,远端动脉血流峰速(S2)降低(19.10±3.91)cm/s;阻力指数(RI)降低(0.38±0.07);收缩期血流加速时间(SAT)延长(98.00±9.41)ms;行经皮血管成形术,当狭窄部分、全部解除时,肝动脉各段血流峰速均相应不同程度向正常恢复,S1为(73.68±8.81)cm/s;S2为(37.18±4.80)cm/s,而阻力指数仍长时间维持降低(0.42±0.06),SAT长时间维持延长(98.20±6.80)ms.结论 彩色多普勒超声在肝移植术后发生肝动脉狭窄及其围介入治疗中具有较高监测价值。
