Abstract： 目的探讨彩色多普勒超声(CDFI)在胰肾联合移植(SPK)术后的应用价值.方法用CDFI定期连续观测18例SPK患者术后移植胰腺及移植肾的声像图特征和动静脉血流变化,同时将移植胰腺与患者自身胰腺相比较.结果18例SPK患者术后早期移植胰腺均出现体积增大,形态饱满,内部回声减低,与自体胰腺相比较,差异有统计学意义(P＜0.05);移植胰的胰头及胰尾部增大较明显,多在数10 d至1个月后逐渐恢复正常.其中出现并发症5例(5/18,28%).急性排斥反应2例(2/18,11%).超声图像特征为:移植肾体积增大,实质增厚,各级动脉血流阻力指数(RI)增高(均在0.80～1.0之间);移植胰腺周围出现局限性积液暗区,移植物腹腔干动脉RI波动在0.67～0.78之间.1例移植胰胰腺炎声像图特征为:移植胰腺体积明显增大,内部实质回声不均,胰周积液不断增多,移植物腹腔干动脉RI＜0.7,移植肾声像图正常.CDFI诊断右侧髂外静脉及属支部分栓塞1例(1/18,6%);移植物腹腔干动脉血栓栓塞1例(1/18,6%).结论CDFI在胰肾联合移植中具有重要的应用价值.
