摘要 目的探讨多层螺旋CT血管成像在血液透析患者自体动静脉内瘘功能不全中的临床价值。方法采用16层螺旋CT对14例自体动静脉内瘘功能不全的患者进行血管成像检查。对扫描的图像进行后处理,分别采用曲面重建(CPR)、最大密度投影(MIP)和容积成像(VR)进行三维重建。观察自体动静脉内瘘血管的显示情况。结果14例患者中,单纯吻合口狭窄1例;流入动脉狭窄3例,其中多处狭窄2例;流出静脉狭窄6例,其中多处狭窄3例,伴有明显的静脉侧支循环1例;流入动脉及流出静脉同时狭窄1例;流入动脉、流出静脉及吻合均狭窄1例;仅有动脉粥样斑块但无明显狭窄2例。并依据此结果,对12例患者进行了动静脉内瘘手术,其中8例在原内瘘同侧近心端手术,均获满意效果。结论多层螺旋CT血管成像检查相对无创、空间分辨率高,可以多角度、多方位、立体地显示内瘘血管病变,为自体内瘘功能不全的患者提供了1种有效的检查方法。
