区中医医院肾病科联合超声科开展
“经皮动静脉内瘘狭窄球囊扩张术”获成功
号外！号外！
区中中医院又一手术取得圆满成功！
让我们为参与这次手术的医务人员
送上热烈的掌声！
近日，区中医医院肾病科联合超声科开展“经皮动静脉内瘘狭窄球囊扩张术”，手术取得完满成功。
患者为60岁男性，平日里在区中医医院门诊血液透析中心进行规律血液透析治疗，治疗中因“发现血透中血流量不足1周”，立即转入我院肾病科住院，经检查后发现内瘘震颤明显减弱，被诊断为内瘘流出道狭窄。
▲头静脉血管节段狭窄
肾病科和超声科在对患者的病情进行探讨后，共同制定了治疗方案，确定为患者行“经皮动静脉内瘘狭窄球囊扩张术”。
手术过程中，医务人员在患者内瘘侧近心端顺行穿刺头静脉，在超声引导下，将导丝经血管鞘送入，并通过狭窄处，再沿导丝送入球囊导管，将球囊定位于狭窄处，扩张狭窄段血管，连续扩张2次。
▲球囊继续加压，血管狭窄部出现双凹征逐渐消失
超声实时观察球囊扩张状态，直至球囊压迹消失，最后超声显示狭窄段血管完全再通，手术取得成功。
▲术后头静脉血流量满足血液透析要求
动脉和静脉之间的通道被称为动静脉内瘘，是血液透析患者最好的长期血管通路。内瘘狭窄和闭塞是其常见并发症，会直接影响患者透析效果及生活质量，同时会间接影响患者的生存。
以往的手术通常采用外科手术方法处理动静脉内瘘狭窄，即手术切除狭窄段重新吻合血管或在其它部位建立内瘘，这对血管损伤大，且多次手术破坏血管资源，使可用于透析治疗穿刺的血管长度减少，甚至失去重建内瘘的可能性，所以很多患者及家属都不愿接受。
经皮动静脉内瘘狭窄球囊扩张术是治疗动静脉内瘘狭窄和闭塞的有效方法，具有操作简单、创伤小、不损害患者血管等优点，最大限度地保护了患者的血管资源，延长了内瘘的使用时间，保证患者的透析安全。
