1、·36中华腔镜泌尿外科杂志(电子版)2014年6月第8卷第3期ChinJEndourolok-~(ElectronicEdition),June2014.Vo1.8.No.3临床研究多层螺旋CT血管造影在血管压迫所致肾盂输尿管连接部梗阻中的诊断价值胡辉军李国照陈娇霞段小慧沈君【摘要】目的探讨多层螺旋CT血管造影(CTA)对血管压迫所致肾盂输尿管连接部梗阻(UPJO)中的诊断价值。方法分析手术证实的16例血管压迫所致UPJO患者的CT血管造影图像,观察有无肾脏血管变异,肾盂输尿管连接部周围有无骑跨血
2、管、血管的起源、大小及其与UPJO间的关系。结果16例UPJO中,肾动脉解剖变异12例,。肾静脉解剖变异3例。CTA16例见19支血管压迫,其中动脉血管15支,静脉血管4支。单支血管压迫13例,双支血管压迫3例,包括副。肾动脉12例,迷走动脉3例,性腺静脉2例,副肾静脉2例。均与手术病理相吻合。结论多层螺旋CTA不但能够了解肾脏血管解剖及变异,并且在血管压迫所致UPJO的诊断及手术治疗方面具有重要价值。【关键词】肾盂输尿管连接部梗阻;体层摄影术;X线计算机;血管造影;异位血管Diagnosticv
