摘要
目的 探讨CT在肿胀手综合征中的临床应用价值.方法 对49例应用自体动静脉内瘘并形成肿胀手综合征的维持性血液透析患者应用64排CT血管成像技术（CTA）检查,并采用容积重建（VR）、最大密度投影（MIP）、多平面重建（MPR）等方式进行图像三维重建,观察内瘘血管的流入道、流出道及吻合口有无狭窄,以及血管病变的部位、程度、范围及侧支循环情况.结果 49例中单纯吻合口狭窄3例（6.1%）;头静脉狭窄15例（30.6%）,其中轻度6例,中度4例,重度5例;锁骨下静脉狭窄18例（36.7%）,其中轻度8例,中度5例,重度5例;无名静脉重度狭窄1例（2.0%）;上腔静脉重度狭窄6例（12.2%）,闭塞6例（12.2%）.结论 当维持性血液透析患者发生肿胀手综合征时,首选CT血管成像技术,对诊断和进一步的临床干预都有很大的指导临床应用价值.
Objective To investigate the clinical value of CT angiography（CTA） in the assessment of swollen hand syndrome in patients on maintenance hemodialysis.Methods Forty-nine maintenance hemodialysis patients were studied with MS-CTA（GE 16）,followed by digital vascular reconstruction （autobone for bone removal,vessel analysis for caliber and length measurements,thin and curved MIP,MPR）.Results Fifteen cases had cephalic veinstenosis （six cases with mild stenosis,four cases with moderate stenosis and five cases with severe stenosis）,18 cases had subclavian vein （eight cases with mild stenosis,five cases with moderate stenosis,five cases with severe stenosis）,one case had innominate veins severe stenosis,one case had innominate veins thrombosis,6 cases had superior vena cava severe stenosis and 6 cases had superior vena cava obstruction.Conclusions CTA is the preferred technique in the assessment of swollen hand syndrome in patients on maintenance hemodialysis,not only for diagnosis but also for further clinical intervention has great guidance application value.
