A common problem in the management of hemodialysis patients is central venous occlusive disease. There has been extensive literature on the treatment of this important and prevalent problem. Treatment options to date include percutaneous balloon angioplasty, bare metal stents and surgical bypass. Unfortunately, all the available treatment options have poor long-term patency, requiring repetitive intervention. More recently, covered stents have been mentioned in the literature for the treatment of central venous stenosis and obstruction. There is very little data to date on this technology, and further randomized controlled trials will be needed to compare the efficacy of percutaneous balloon angioplasty, bare metal stents and covered stents. It appears prevention of this difficult problem is paramount, by limiting venous access or intervention of the central venous system.
血液透析患者管理中的一个常见问题是中心静脉闭塞性疾病。关于这个重要且普遍存在的问题的治疗，已有大量文献。迄今为止的治疗选择包括经皮球囊血管成形术、裸金属支架和外科搭桥术。不幸的是，所有现有的治疗选择长期通畅性都很差，需要重复干预。最近，文献中提到了覆膜支架用于治疗中心静脉狭窄和阻塞。迄今为止，关于这项技术的数据非常少，需要进一步的随机对照试验来比较经皮球囊血管成形术、裸金属支架和覆膜支架的疗效。通过限制静脉通路或对中心静脉系统进行干预，预防这个难题似乎至关重要。
