血液透析血管通路功能障碍是血液透析患者发病和死亡的主要原因。这种血管通路功能障碍的最常见原因是吻合口周围区域(AV瘘)或移植物-静脉吻合口(PTFE移植物)处的静脉新生内膜增生导致的静脉狭窄。迄今为止,静脉新生内膜增生的有效治疗方法很少,部分原因是对静脉新生内膜增生的发病机制认识不足。因此,本文将(1)描述动静脉瘘和移植物中血液透析通路狭窄的病理学,(2)回顾和描述新生内膜增生形成发病机制的当前和新概念,(3)讨论治疗静脉新生内膜增生的当前和未来新疗法,(4)建议血液透析血管通路功能障碍领域的未来研究领域。
Hemodialysis vascular access dysfunction is a major cause of morbidity and mortality in hemodialysis patients. The most common cause of this vascular access dysfunction is venous stenosis as a result of venous neointimal hyperplasia within the peri-anastomotic region (AV fistula) or at the graft-vein anastomosis (PTFE grafts). There have been few effective treatments to-date for venous neointimal hyperplasia in part because of the poor understanding of the pathogenesis of venous neointimal hyperplasia. Therefore, this article will (1) describe the pathology of hemodialysis access stenosis in AV fistulas and grafts, (2) review and describe both current and novel concepts in the pathogenesis of neointimal hyperplasia formation, (3) discuss current and future novel therapies for treating venous neointimal hyperplasia, and (4) suggest future research areas in the field of hemodialysis vascular access dysfunction.
