Of the 283, 932 patients with end stage renal disease (ESRD) receiving replacement therapy in the US in 1996, 62% were being treated with haemodialysis. Improved survival of haemodialysis patients coupled with the inability to provide enough renal transplants for the growing ESRD population has resulted in an increase in the average length of time patients spend on dialysis. Vascular accesses are, therefore, required to function for longer periods of time. Maintenance of a reliable access to the circulation has been described as the Achilles' heel of modern haemodialysis. Preserving access function and long-term patency are essential for efficient dialysis delivery.
1996年在美国接受替代治疗的283,932例终末期肾病（ESRD）患者中，62%接受血液透析治疗。血液透析患者生存率的提高，加上无法为不断增加的ESRD患者群体提供足够的肾移植，导致患者透析的平均时间增加。因此，血管通路需要具备更长时间的功能。维持可靠的血液循环通路被认为是现代血液透析的薄弱环节。保持通路功能和长期通畅对于高效透析至关重要。
