摘要: |
目的:本研究应用彩色多普勒高频超声评价自体动静脉内瘘吻合口处内膜增生与动静脉内瘘狭窄的关系。方法:动静脉内瘘口狭窄组患者共18例,动静脉内瘘口局部狭窄处峰值流速与流入道动脉峰值流速比值≥2.5,临床透析过程持续出现透析血流量不足情况。对照组18例,自体动静脉内瘘超声检查未见明显并发症,透析过程中无血流量不足情况。详细记录患者动脉内瘘吻合口内径、内瘘口处内膜厚度、动静脉内瘘血流量及瘘口处与流入道动脉峰值血流速度比值。结果:动静脉内瘘口狭窄组动静脉内瘘口处内径及动静脉内瘘血流量明显低于正常组(P<0.05),动静脉内瘘口狭窄组动静脉内瘘口处内膜厚度及血流速度比值明显高于正常组(P<0.05)。结论:动静脉内瘘口处狭窄患者局部内膜明显增厚,高频彩色多普勒超声可直观准确的评价动静脉内瘘吻合口处管腔变窄及局部内膜增生程度。 |
