【摘要】：目的分析总结189例肿胀手综合征患者的CT血管造影表现,探讨肿胀手综合征的中心静脉CTA特点。方法本组189例肿胀手综合征患者,男性84例,女性105例,年龄27~84岁,平均年龄(63.78±12.86)岁。本组病例均为维持性血液透析患者,血管透析通路建立时间5~184个月,平均(37.35±25.59)个月。CT血管造影图像经AW4.4工作站,应用最大密度投影、容积成像和曲面重建技术对图像数据进行处理和三维重建。结果 189例CT血管造影检查均获得了满意图像,血管狭窄病变73例,占38.6%(73/189),血管狭窄程度≥80%;血管闭塞病变116例,占61.4%(116/189)。104例在介入诊疗中,经数字减影血管造影(DSA)证实。结论肿胀手综合征是血液透析常见并发症,主要是因中心静脉狭窄或闭塞所致。CT血管造影可清晰显示中心静脉狭窄、闭塞的程度及部位,为临床治疗,特别是介入治疗提供准确的影像学信息,具有很高的临床应用价值。
[Abstract]:Objective to analyze and summarize the CT angiography findings of 189 patients with swollen hand syndrome and to explore the central venous CTA features of swelling hand syndrome. Methods 189 patients with swelling hand syndrome, including 84 males and 105 females, aged 2784 years, with an average age of (63.78 卤12.86) years. All the patients were maintainable hemodialysis patients. The time of establishing the vascular dialysis pathway was 5 ~ 184 months (mean 37.35 卤25.59) months. CT angiography was performed by AW4.4 workstation and the maximum density projection was used. Volume imaging and surface reconstruction are used to process and reconstruct the image data. Results satisfactory images were obtained in CT angiography. 73 cases (38.6%) had stenosis, and the degree of stenosis was more than 80%. There were 116 cases of vascular occlusive disease (111.4%), 104 cases were confirmed by digital subtraction angiography (DSA) in interventional diagnosis and treatment. Conclusion swelling hand syndrome is a common complication of hemodialysis, mainly caused by stenosis or occlusion of central vein. CT angiography can clearly show the degree and location of central vein stenosis and occlusion. Especially interventional therapy provides accurate imaging information and has high clinical application value.
