Long-term indwelling central venous catheters (CVCs) may cause complications, such as central venous disease (CVD). CVD eliminates the possibility of establishing new arteriovenous access. We herein describe a case in which an arteriovenous graft (AVG) is implanted through the peripheral veins and blood flows back to the patent azygos vein, secondary to superior vena cava stenosis. This shows that if the CVD is correctable or the collateral circulation is an alternative vascular pathway that allows blood to return back to the right atrium, the internal fistula flow is well-balanced with the collateral circulation and there are no clinical symptoms of CVD, an arteriovenous access can be established for the operation. This provides a viable, long-term vascular access option for hemodialysis patients with central venous resource depletion.
长期留置的中心静脉导管（CVC）可能会引起并发症，如中心静脉疾病（CVD）。CVD 消除了建立新的动静脉通路的可能性。我们在此描述了一例因上腔静脉狭窄，导致通过外周静脉植入动静脉移植物（AVG），血流回流至通畅的奇静脉的病例。这表明，如果 CVD 是可纠正的，或者侧支循环是允许血液回流到右心房的另一种血管通路，那么内瘘流量与侧支循环平衡，并且没有 CVD 的临床症状，就可以为手术建立动静脉通路。这为中心静脉资源枯竭的血液透析患者提供了一种可行的、长期的血管通路选择。
