维持性血液透析是终末期肾脏疾病患者维持生命的重要治疗手段,而动静脉内瘘为其首选长期血管通路,具有满意的血流量是保证患者透析充分性、生活质量乃至长期存活的关键~([1])。而具有过高血流量的动静脉内瘘可导致心输出量(cardiac output,CO)增加,加重心脏负担,甚至发生高输出量心力衰竭~([2]),必要时需采取手术干预措施~([3])。笔者报道应用人造血管 Maintenance hemodialysis is an important treatment for end-stage renal disease in patients with life-sustaining, and arteriovenous fistula is its preferred long-term vascular access, with satisfactory blood flow is the key to ensure adequate dialysis, quality of life and long-term survival ~ ( [1]). Arteriovenous fistulas with excessive blood flow can lead to increased cardiac output (CO), increased cardiac burden, and even high-output heart failure ~ ([2]) and require surgical intervention if necessary ([3]). I report the application of artificial blood vessels
